5 Tips to Buy Caustic Soda

5 tips to buy caustic soda:

In a competitive world which there are hundreds of manufacturers, suppliers and exporters of caustic soda, importers and end-users have a difficult job to consider all the important factors of a good purchase, and make the best choice. In this article, we want to share some useful information about the ways how an importer can make a better decision to buy caustic soda considering these tips;

1- Choose the right supplier:

Regardless of the fact that the supplier is a manufacturer or a trader, it should be able to give you the most competitive and smoothest services. Your right caustic soda supplier should be able to offer you reasonable rates, and deliver the cargo on the due time. Your caustic soda supplier should also be able to offer you smooth shipping services with economical rates. Sometimes, the goods’ price is ok, but the freight charge is deal breaker. So, your supplier should be reliable in the market and get the most competitive rates from the top key players in shipping industry of the country.

Last and most important point is that your supplier must be honest and fulfill all the commitments they promise.

For example, imagine you have invested a considerable amount to buy caustic soda, or have guaranteed to a tender contract to supply caustic soda for a private or governmental sector in your country. Your supplier gives you the proforma invoice, and promise to deliver the cargo within one week after they receive the payment from you. You pay the amount, but receive the cargo only after a delay of 20 days. In this way, no money or product quality can compensate for your credit loss in front of your local customers. So, a reliable and honest supplier should be the most important factor for you to buy caustic soda.

2- Don’t get carried away with unbelievable caustic soda prices:

It is always a nice dream to find a price which is below the range of market price, and make a huge profit. But, the English say “we are not that rich to buy cheap things.”

Sometimes you may face with unbelievable prices from a caustic soda manufacturer or trader. Good for you, congrats! But, before proceeding to pay and place the order, we highly recommend to check the below possibilities;

  • The cargo may have been kept at the warehouse for a long time. It may have lost the purity, or shape. You may pay for caustic soda flakes, but once you receive the cargo at your destination, you see that you have bought caustic soda lumps which are stuck to each other like a mass of stone-shape, and there are not any flakes!!
  • The manufacturer may use salt, low quality caustic soda lye and other impurities for producing caustic soda flakes in order to reduce their production costs. In this case, the specifications may not match your requirement at all.

Sometimes, a manufacturer or trader may offer those unbelievable prices to promote its product and brand, and the quality of the cargo may also be ok. But, it is necessary to check the cargo quality and specifications to prevent any risk for the amount you are going to pay to such supplier.

3- Consider the supply capacity:

Basically, there are two types of caustic soda manufacturers; chlor-alkali plants and factories that buy caustic soda lye and make it flakes.

Most of those chlor-alkali plants have bigger production capacities. So, if you want to place bulk orders like 500 MT and above, and would like to receive the whole quantity in a short time, these factories can be your suitable choice.

The second type of manufacturers may have smaller production capacity, but they care about their customers more and seem to be more flexible about the price, quality, payment term and customer-care services comparing to those giant chlor-alkali plants in order to keep the relationship with their customers and make them satisfied to buy from them.

So, depending on your quantity requirement, you should note the production capacity and delivery time of the supplier you are going to buy from.

4- Try to buy caustic soda on CFR/CPT basis:

As a foreign customer located in another country thousands of miles away from the supplier’s location, it is very difficult to take the cargo on EXW or FOB basis, and arrange the shipment on your own. Especially, as there are some limitations for shipping from Iran, you may get confused which shipping company can do the job for your shipment, how you should arrange the shipping documentation, which port is better and closer to your final destination, which shipping line has shorter transit time for your destination, and etc. all these factors are fundamental in logistics in order to prevent any risk and control your import costs to buy caustic soda.

So, it is an important necessity to buy caustic soda from a supplier who is expert in international transportation, and can deliver the cargo to your destination in a smooth way with cost-effective rates.

5- Check the supplier’s accountability in the market:

Once the market gets booming for a specific product in a country, so many people may decide to rent a workshop and start producing that product. They may not have any professional experience in manufacturing that product. So, there are so many risks to buy from a new-established manufacturer.

Our suggestion is that regardless of the adverts and claims the new manufacturer may do, you should check its accountability in the market, its product quality and specification, and also check their packing quality before placing any order with them. Checking the details before paying any money will keep you on the safe side.

You can have a better choice to buy from a caustic soda supplier which has many years of experience in the same field in the local market and knows all the territory manufacturers in details, have strong buiness relationship with giant governmental  chlor-alkali plants and reliable caustic soda producing workshops. So, that supplier can keep your back, and arrange your caustic soda orders in the smoothest way on regular basis.

Caustic Soda Manufacturers in China

Caustic Soda Manufacturers in China

China is a leading manufacturer and exporter of caustic soda in the world. In the last decade, they have exported caustic soda to so many countries with interesting prices for importers. But, during last few years, the Chinese government has imposed some economic and environmental restrictions and regulations for local chemicals manufacturers. These limitations have caused some differences in caustic soda prices in China. We could see that in 2017, shutdown of caustic soda plants in China caused a drastic increase in caustic soda global prices, and global importers were looking for other alternatives than China. As per the new environmental and economic road map of Chinese government, it seems the same situation will continue.


Tejaras Co. as a leading manufacturer and exporter of caustic soda flakes from Iran can be a great alternative for caustic soda flakes and caustic soda lye requirements around the world.

State-of-the-art manufacturing facilities of detergent chemicals and raw materials in top governmental plants, has made us able to supply highest quality detergent chemicals and raw materials at most competitive prices.

Caustic Soda

Caustic soda in 2 types are used in detergent industry; caustic soda liquid 48-50% and caustic soda flakes 98-99%. Caustic soda ( sodium hydroxide ) is one of the most important raw materials in manufacture of detergent chemicals. It is used in saponification, the process that converts vegetable oils into soap. Caustic soda is also used to produce anionic surfactants which are largely used in detergent chemicals and cleaning products.

Linear Alkyl Benzene Sulfonic Acid ( LABSA 96-97% )

LABSA, sulfonic acid also known as acid slurry is one of other major detergent chemicals we export. LABSA is the most common anionic surfactant for synthetic detergent powder. There are some important factors that detergent manufacturers prefer sulfonic acid to other anionic surfactants. We can point out good solubility in water, high detergency and foaming, and economical prices among those important factors.

Soda ash light ( sodium carbonate )

soda ash also known as washing soda is also among major detergent chemicals. Soda ash is used as the builder ( washing auxiliary ) in detergent industry. Its main application is to be used as a solvent which can remove a wide range of stains. Also, soda ash can be dissolved in water in order to create a pre-soaking solution for tough stains like coffee, tea, blood, grease, and oil.

Sodium Lauryl Ether Sulfate ( SLES 70% )

SLES, sodium lauryl ether sulfate, also known as Texapon is one of other major detergent chemicals we supply and export. SLES is widely used in liquid detergent such as shampoo, hand washing liquid, dishwashing detergent, and bubble bath liquid.

Sodium hypochlorite

Sodium hypochlorite is the most powerful home bleach. Using sodium hypochlorite aids detergent products in the removal of stains and soil. Once sodium hypochlorite is used in the wash, it acts as a disinfectant on bacteria and viruses and generally whitens most natural-fiber fabrics like cotton.

Mining Chemicals – Chemicals Used in Mining

Mining Chemicals – Chemicals Used in Mining

In this post you will study some of the most widely traded and used mining chemicals.

Mine Explosives and Drilling Chemicals:
    • Acetic Acid: Additive in industrial explosives
    • Sodium Nitrate: Initiator in industrial explosives
    • Sodium Nitrite: Initiator in industrial explosives
    • Sodium Perchlorate: Initiator in industrial explosives
    • AN Prills : base in industrial explosives
Flotation in Mining – Collectors and Modifiers:

There are many possible ways of categorizing sulfide collectors; e.g. copper collectors, lead collectors, soluble collectors, oily collectors, thiol collectors, etc. The terms “collector” and “promoter” are often used synonymously. Other reagents, which assist the adsorption of a collector on the mineral surface, are referred to as “activators”, and their use is also discussed below.


Most widely used Xanthate in the flotation process in mining:

  • Potassium Amyl Xanthate (PAX): Strong, unselective collector
  • Sodium Ethyl Xanthate (SEX): Weak, highly selective collector
  • Sodium Isobutyl Xanthate (SIBX): Good general purpose collector
  • Sodium Isopropyl Xanthate (SIPX): Selective collector with higher recovery than SEX
Modifying Agents:

a huge number of reagents usually referred to as “Modifying agents” are used in the flotation of sulfide ores. This is especially true in the case of complex ores, where two or more valuable minerals have to be separated from each other, e.g. Pb/Zn ores, Cu/Zn ores Cu/Pb/Zn ores, Cu/Mo ores, Cu/Ni ores etc.

These modifying agents cover a variety of functions; for example, pH modifiers, depressants, activators and dispersants.

pH Modifiers:

Most minerals exhibit an optimum pH range for a given collector. While some minerals can often be floated at the natural pH of the ores, in most cases the pH has to be adjusted for maximum recovery and selectivity. The most widely used reagents for alkaline circuits are lime and soda ash.

For acid circuit flotation, the most commonly used reagent is sulfuric acid. These three modifiers are generally the most cost-effective ones. Other pH modifiers are also used rarely when difficult separations are required.

Common pH Modifiers:
  • Sodium Cyanide /NaCN: Strong sulphide depressant for iron and zinc sulphides (e.g. pyrite, pyrrhotite, marcasite, arsenopyrite, sphalerite).
  • Caustic soda/ Sodium Hydroxide /NaOH : Used to raise pH
  • Soda ash /Sodium Carbonate / Na2CO3 : Used to raise pH
  • Sulphuric Acid / H2SO4 : Used when flotation needs to be at a lower pH.
Inorganic Depressants:

The principal ones used and their typical applications are as follows:

  • Sodium Cyanide: Depression of iron sulfide minerals such as pyrite, pyrrhotite and arsenopyrite. Depression of Zn minerals during Pb flotation from Pb/Zn ores.
  • Sodium Ferro cyanide: Depression of Cu and Fe sulfide in Cu/Mo separation.
  • Zinc Sulfate: Used alone, or in combination with cyanide, for depression of Zn minerals in the flotation of Pb/Zn, Cu/Zn, and Cu/Pb/Zn ores.
  • Sodium Metabisulphite/SMBS: Depression of Zn sulphide (sphalerite) and Fe sulphide (e.g. pyrite, pyrrhotite) minerals.
  • Hydrate Lime: Depressant for pyrite during copper and zinc flotation and in other sulphide ores where pyrite is a problem.
  • Citric Acid: Organic Acid gangue depressant for ores containing oxide minerals
    Sodium sulfide & Hydrosulfide (NaHS): Used for the depression of Cu and Fe sulfide minerals in Cu/Mo separation.
  • Nokes Reagent: Used for the depression of Cu and Fe sulfide minerals in Cu/Mo separation.
  • DETA (Diethylene triamine): Used for the depression of pyrrhotite in Cu/Ni ores.
  • Permanganates & other oxidizing agents: Can be useful in the separation of pyrite from arsenopyrite
  • Yellow Dextrin, Starches: Used in the depression of weathered silicates and carbonaceous matter.
  • Carboxymethyl cellulose /CMC: Used in the depression of magnesium silicates such as talc and pyroxene. Especially useful in the flotation of PGM and Ni ores.
  • Guar gum: Depression of silicate gangue (e.g. talc, serpentine, lizardite, antigorite).




Certain minerals do not float well with the use of only a collector, but require prior activation. The most commonly used activators are:

  • Copper Sulphate /CuSO4: Activation of Zn sulfide and Fe sulfide minerals such as pyrite and pyrrhotite when the latter contain values such as Au, Ni and PGM elements.
  • Lead (Pb) Nitrate or 
Pb Acetate: Used for the activation of antimony sulfide minerals such as stibnite and to reactivate copper sulphides depressed with cyanide.
  • Sodium Sulphide (Na2S) /Sodium Hydrosulphide (NaHS): Commonly used prior to collector addition for the activation of Cu, Pb, and Zn minerals. The choice of whether to use Na2S or NaHS depends on the pH required in flotation, as Na2S is more alkaline and also, whichever works best (test to verify). Typically made up to 15-25 % solution strength.
  • NaCN/ Sodium Cyanide: Acts as a surface cleaning agent or “activator” to improve the flotation of PbS.

Many ores contain significant quantities of clay minerals and other “primary slimes”. These can have an adverse effect on flotation metallurgy. This can be due to a combination of factors such as, (a) increasing pulp viscosity, which adversely affects air bubble distribution, and froth drainage/mobility; (b) slimes can form a coating on the surface of valuable minerals thereby inhibiting their flotation.
The usual practice for minimizing the aforementioned effect of “slimes” is to conduct the flotation at lower percent solids to reduce the pulp viscosity. However, this also reduces the effective residence time in the flotation circuit. Consequently the use of both inorganic and organic dispersing and viscosity reducing agents is commonly practiced. Sodium silicate, soda ash, various poly- phosphate.
