ARTICLE ANNOTATION

quote
The article deals with the development of a technological scheme of a phased technology of flotation of hard-to-rich and persistent gold-bearing ores. The results of laboratory tests of difficult-to-enrich gold-arsenic polymetallic ores of Uzbekistan deposits are substantiated. On the basis of the taken several crushed samples of different size, used in the enrichment by flotation method, without changing the reagent flow rate, the optimal technological scheme for the extraction of high-quality gold-containing concentrate. As a result of the laboratory work, a composition of unreacted useful components sent to the tails was obtained and more qualitative gold-containing concentrate was drained.The most acceptable result of the laboratory work was the enrichment of ore according to the selective scheme to obtain 45.38% g / t of gold, 3.97% arsenic, 23.83% sulfur, 4.74% alumina preserving enrichment, while the breakdown of gold for enrichment is 93.5%, and the breakdown of silver for enrichment as a satellite element-34.6%. The obtained results were achieved only in laboratory conditions, if at present the technological scheme recommended in the article for gold extraction ore is implemented at the gold recovery plant in our Republic, then it is possible to achieve the separation of gold for enrichment above 90% and reduce the number of harmful additives.
