5. RECOMMENDED USE
Pre‑elution treatment of activated carbon in gold mining
The mining industry relies heavily on the acid leaching of certain minerals from ore deposits, an economical method of recovering valuable minerals from otherwise inaccessible bodies of ore.
Hydrochloric Acid can be used in the following stages at the mine:
- Acid Washing
- Acid Wash Cycle
- Acid Soak Cycle
- Acid Rinse Cycle
6. CARBON ACID WASHING
Carbon fouling is the buildup of organic and inorganic substances on carbon, which detrimentally affects carbon adsorption by reducing carbon activity.-- Hydrochloric Acid washing removes inorganic foulants from the carbon.
Acid washing is also critical in the AARL process to ensure elution efficiency.
Our standard grades are : 31%, 33% & 35% which are widely used based on specific application.
Hydrochloric acid is consumed in many mining operations for ore treatment, extraction, separation, purification, and water treatment. Significant quantities are used in the recovery of molybdenum and gold. Hydrochloric acid is used to convert high-grade scheelite concentrate (CaWO4) and crude sodium tungstate to tungstic acid, which in turn, can be used to produce tungsten metal and chemicals. Hydrochloric acid is also used in uranium and zirconium processing, solution mining of borate ores, as a pH regulator in the froth flotation of potash ores, and in rare earth extraction from bastnasite.
Hydrochloric Acid is a colourless, pungent solution of hydrogen chloride in water. It is highly corrosive mineral acid with wide range of uses in industry.
7. THE MAJOR USES OF HCL ARE:
- Large scale production of vinyl chloride for PVC plastic
- Prickling/cleaning iron and steel components before galvanizing
- Regeneration of ion exchangers
- Activated Carbon regeneration in gold mining
- Production of MDI/TDI for polyurethane

It is a colourless liquid that when undiluted is also called glacial acetic acid. It has a distinctive sour taste and pungent smell.
Acetic acid uses: Additive in industrial explosives in Mining.
Other uses include use of acetic acid in the production of vinyl acetate monomer, acetic anhydride and ester production.
Chemical gassing agents -In the case of emulsion explosives, using Acetic acid can accelerate the gassing process. The chemically gassed emulsions may take 40 – 50 minutes for completion of gassing within the blast holes, particularly when the emulsion is colder.
In cases where acetic acid is used, it is added to the emulsion prior to gassing, the desired amount of acid is mixed in the emulsion, before adding the gasser.
A gassing solution comprising sodium nitrite in water together with the selected enol compound and acetic acid is introduced into the emulsion explosive at the blast hole by entraining the gassing solution into a stream of the emulsion explosive using pumps.
The solution pH is an important parameter in the gassing of emulsion explosives due to the high cost associated with acid addition therefore a pH value should preferably be maintained at 4.1 or below.

4.Environmental impact
- Acetic acid biodegrades readily under both aerobic and anaerobic conditions.
- Acetic acid does not absorb light with wavelengths >290 nm(4), and is not expected to be susceptible to direct photolysis by sunlight(SRC).
- Incase of spillage neutralize spill with soda ash or lime.
