According to the zinc ore characteristics, Xinhai adopted pre-desliming, zinc sulfide flotation and zinc oxide flotation process. Finally, the production indexes were stable and the recovery rate of zinc reached 69.56 . .
Flotation is the conventional method for processing porphyry copper deposits, one of the most economically important sources of copper (Cu) worldwide. The rapidly decreasing grade of this type of Cu ore in recent years, however, presents serious problems with fine particle recovery using conventional flotation circuits.This process has seen significant productivity cadmium and cobalt also occur in the ore in higher quantities. The life of the mine has been lengthened with the discovery of further ore prior to flotation. This means that 70 of the total ore reports to flotation at the designed head grades. Higher.
Stabilization With improved flotation controls, the flotation circuit can be operated with tighter safety margins – i.e. the process can be run closer to the minimum grade limit. Optimization Improved process conditions (less turbulence, consistent drainage and entrainment, constant mass pull, and so on) enable higher recovery with.Jun 12, 2017 Base metals such as copper, lead, and zinc are mainly extracted from sulfide ores. Mostly these base metals tend to exist together in an ore. Flotation process is widely used to separate these minerals in sulfide ores . A wide range of chemical reagents are used in the flotation process to separate the different minerals.
Mar 15, 2019 In the flotation of oxided ore, fatty acids and its sodium soaps, alkyl sulfonates, alkyl sulfates, phosphates and arsenates are commonly used collectors. In addition, kerosene and diesel are generally used as oil flotation collectors for gold recovery chemicals.
