Adopting mixed flotation-concentrate regrinding process can reduce the grinding cost, and be easy to manage. Application of new non-toxic flotation reagents is efficient and environmental protection.
Coarse concentrate regrinding and re-separating improves the concentrate index; Determine concentrate regrinding and re-separating process according to the ore properties; To reduce energy consumption by 30%, recovery rate is increased by more than 10%.
Wolframite consists of the quartz dyke type ores and veinlet tungsten ores. Dissemination size of ores is relatively coarse, so it is easy to separation.
Scheelite dressing can use gravity, magnetic and flotation separation. The types and properties of the ore decide the separation methods and processes. Basing on good floatability of scheelite, the flotation is selected.
