The ore particle size is crushed to 10-12mm or less by three-stage-crushing with single closed circuit stage process to reduce the load of the grinding system. High recovery rate; During the process, because leaching and adsorption take place simultaneously, so the gold dissolves quickly and the recovery rate of soluble gold is greatly improved.
Gold beneficiation processing. Roasting: Where gold is trapped in sulfides such as pyrite, roasting of the concentrate is required to convert the sulfides to oxides (called calcine), with sulfur in the sulfides liberated as sulfur dioxide. Oxidation is necessary for the subsequent gold leaching and recovery processes to operate effectively.
