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.
