Реферат | The results of gold extraction of refractory ores, contained finely impreguated gold and silver in sulphides have been presented. The technological schemes, included thermal chemical (final roasting) or hydro-metallurgical (autoclave and bacterial leaching) methods of sulphide oxidation, previous to cyanide gold extraction have been developed. The technology of heap leaching of primary pyritous-arsenic pyritous ores with obtaining high indice of gold extraction from products of heap bacteria leaching has been proposed. |
Ключевые слова | Bacterial leaching, refractory ores, gold, sulphide decomposition, technological scheme. |
