Russia’s gold mining industry will see a twofold growth in domestic production of calcium hypochlorite.
The enterprise of PAO Khimprom, based in the Chuvash Republic, plans to increase production of this essential chemical agent. The role of calcium hypochlorite, an inorganic compound that comes in a form of a white granular solid resistant to dry atmosphere, is highly important.
The reagent reacts with hydrochloric acid to form calcium chloride, which when reacting with gold forms water-soluble auric chloride; the method of precipitating gold from solution is rather simple and called chloride leaching.
Calcium hypochlorite is also used in paper and fabric production for bleaching, and for sewage water disinfection.
Launching the second stage of the calcium hypochlorite production in Chuvashia will satisfy demands for the chemical reagent in the Russian market, which requires about 30,000 tons annually.
