Hydrochloric Acid use in Mining: 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 wash cycle
-Acid soak cycle
-Acid Rinse Cycle
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.
The major Hydrochloric Acid uses 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,
- Processing of leathers in the tanning industry.
