Gold mineral flotation normally adopts one stage grinding-flotation process, but stages grinding and flotation for ore with uneven distribution. Grinding fineness of gold. For the gold wrapped in sulfide minerals, sulfide ore reaches monomer dissociation but for the gold with gangue, grinding fineness should reach gold monomer dissociation.Read More
Flotation process maximizes the enrichment of gold into sulfide minerals. The tailings can be directly discharged. Flotation in gold mine has low beneficiation cost. [Application] Gold Flotation Process is use to process fine gold, sulfide gold-containing quartz ore, multi metal gold-containing sulfide ore and carbon-containing ore.
