Process Introduction

Flotation is widely used in gold processing. In China, 80% rock gold is processed by flotation. 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

Process Description

1.Gold mineral flotation normally adopts one stage grinding-flotation process, but stages grinding and flotation for ore with uneven distribution.
2.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. Grinding fineness of minerals is determined by test.
3.Flotation for large density and coarse particle needs thick pulp, whereas for small density and fine particle, need dilute pulp
4.In addition to the grinding fineness, process conditions of gold flotation also includes slurry concentration, reagent dosage, aeration quantity, flotation time
