Description
Technical field
A kind of separation system that molybdenum bismuth is reclaimed in multi-metal sulfide is the utility model is related to, it uses non-cyanide flotation to select
Ore deposit regime of agent, belongs to technical field of beneficiation.
Background technology
Cyanide is inhibitor important in nonferrous metal sulfide mineral flotation, and the Exemplary inhibitors of zincblende, its energy
Effectively suppress pyrite, zincblende and chalcopyrite.A small amount of cyanide can suppress pyrite, and dosage is slightly larger just to be suppressed to dodge zinc
Ore deposit, dosage is some larger, can suppress copper sulfide mineral, but does not have inhibitory action to galena, so, lead-zinc, copper-lead,
The separation of the mineral such as copper-zinc, zinc-sulphur, cyanide are once widely used as selective depressant always.
But cyanide has severe toxicity, in view of the requirement of environmental mining protection, is carrying out find cyanide generation in recent years always
The research of articles for use simultaneously achieves many progress, mainly in terms of the minerals separations such as lead-zinc, copper-zinc, zinc-sulphur, and for molybdenum-
It is less in terms of bismuth separation, because current cyanide substitute is required for first adjusting ore pulp with lime, thus it have impact on returning for molybdenum
Receive index.
The separation of tungsten mines multi-metal sulfide uses cyanide as inhibitor, due to the complexity of separation process,
Still have to be continuing with cyanide as inhibitor.According to《State Council is on further strengthening the work that eliminates the backward production facilities
