| titleOfInvention | Method of gold recovery from gold-containing materials |
| abstract | FIELD: gold hydrometallurgy. SUBSTANCE: method is used in recovery of gold from wastes, secondary materials and electronic scrap with the help of aqua regia. In treatment of gold-containing materials in pickling baths, formed gas-air mixture is subjected to successive passage through alkaline liquor, layer of steel chips in scrubber sprayed with circulating water, and then to catalytic final cleaning. As a result, air is cleaned from hydrogen chloride to maximum allowable concentration and from nitrogen oxides to their residual content not exceeding 0.003 vol.%. EFFECT: provided prolonged efficient operation of cleaning equipment. 2 cl, 1 ex |
