Precious metal beneficiation

Gold ore generally metallic gold or copper, lead and zinc sulfide ores associated form, conventional beneficiation technology reselection gold, flotation beneficiation process. Using the grinding-roughing-sweeping-selection test procedure, a gold concentrate with a gold grade of 80.73 g/t and a recovery rate of 89.4% can be obtained.

Gold mines generally exist in the form of elemental gold or associated with sulfide ore such as copper, lead and zinc. Commonly used gold beneficiation techniques include re-election and flotation. In the ore dressing test study of Shiqiao Gold Mine in Pingdu County, Shandong Province with a crude ore content of 4.31g/t, the grinding-roughing-sweeping-selection test procedure was used to obtain a gold grade of 80.73g/t. 89.4% gold concentrate. For gold mines with high arsenic and high sulfur, a combined process of metallurgy and metallurgy is required. For example, in the ore dressing test of the high-arsenic and high-sulfur gold ore with a crude ore content of 2.56 g/t and arsenic 0.9%, the grinding-flotation-oxidation roasting-cyanide leaching process is used to obtain a gold recovery rate of 83.35%. Technical indicators.

Silver is mainly in the form of sulphur-silver-silver ore, silver-silver ore and silver sulphur-salt minerals. It is a refractory mineral and often uses re-election and flotation. In the experimental study of the Inner Mongolian Chagan Bragan silver mine with a raw ore grade of 464g/t, we used heap leaching-slag slag coarse grinding magnetic separation-magnetic concentrate chlorine salt roasting-calcining fine grinding cyanide-precious zinc In the replacement process, a technical indicator of a silver recovery rate of 82.44% can be obtained.
