[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.
Gold mineral flotation normally adopts one stage grinding-flotation process, but stages grinding and flotation for ore with uneven distribution.
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.
Flotation for large density and coarse particle needs thick pulp, whereas for small density and fine particle, need dilute pulp.
In addition to the grinding fineness, process conditions of gold flotation also includes slurry concentration, reagent dosage, aeration quantity and flotation time.
A manganese ore project of Xinhai its main ore is Rhodochrosite and Ca rhodochrosite then Calcite. Gangue including quartz chalcedony carbonaceous and clay etc. Xinhai contracts the whole designation of the mineral production line and adopts the Process of rough separate the high-intensity magnetic ore and concentrate the medium intensity magnetic ore which guarantee the ore grade can reach 38 and the recovery rate reach 74.
Xinhai can provide the whole EPC service of mineral design and research equipment manufacture installation and commissioning personnel training according to the property of the raw ore. Xinhai has already achieved many designation and reformation of the manganese ore project a project of aboard is a great success. That raw ore including high phosphorus high silicon and low iron lean manganese carbonate 20 manganese ore contained.Rhodochrosite is the main manganese ore apatite is the main harmful element quartz and clay is the main gangue minerals. The magnetic separation production line of the manganese ore reach desired effects and the concentration grade reach 35 and the recovery rate reach 76.
