Физико-Химические И Технологические Особенности Процесса Сократительной Пирометаллургической Селекции Упорного Сырья Золота

Abstract

Based on a critical analysis of existing gold production technologies, the report substantiates the possibility of effective use of high-temperature process of pyrometallurgical selection (RPS-process) of particularly ref types of gold-bearing raw materials. The RPSprocess was studied and tested in laboratory, pilot plant and industrial scale in relation to various in the form of refractory ores and gold concentrates. In this experiment, was shown experimentally that high gold extraction from refractory ores (96-99 %) and gold concentrates from various deposits (95-98 %) into gold-containing mattes, with output from 5 to 10 % of the weight of the processed raw materials.

Optimization of converting process for matte of oxidized nickel ores and sulfide copper ores joint smelting based on thermodynamic simulation

“…Решением указанной проблемы может стать развитие технологий, основанных на принципе совместной переработки руд из месторождений различающихся геолого-промышленных типов [11][12][13][14].…”
