Description
Technical field
The invention belongs to mineral manufacture field, is related under a kind of low alkali from copper zinc indium altogether association polymetallic ore reclaim rich indium
The method of marmatite.
Background technology
Indium as a kind of strategic rare precious metal resource, computer, the energy, electronics, communication, photoelectricity, medicine, health,
The fields such as national defense and military, Aero-Space, nuclear industry and modern information industry have obtained extremely being widely applied.The indium resource of China
Reserves occupy first place in the world, but individually indium mineral deposit is less, the main association of indium in the non-ferrous metal deposits such as copper-lead zinc-tin, such as Yunnan
The common association polymetallic ore of copper zinc-tin, Dachang, Guangxi cassiterite polymetallic sulphide ore, the Mengzi Yunnan Bai Niu factories lead in all imperial mining area of mountain of papers
All it is associated with abundant indium resource in zinc-silver multi-metal sulfide altogether.In these multi-metal sulfide beds, the main preservation of indium in
In marmatite, rich indium marmatite is formed, be enriched with zinc in ore dressing process.
Compared with common zincblende, because iron atom and phosphide atom instead of in zinc blend lattice in rich indium marmatite
Zinc atom, hydrone and hydroxide ion easily adsorb on surface iron atoms and phosphide atom, cause rich indium marmatite
Natural buoyancy is reduced, and is suppressed by stronger under highly alkaline conditions, and conventional activating agent copper sulphate is difficult to efficient work
Change, cause indium and zinc recovery in ore dressing process to reduce.Further, since rich indium marmatite is more and chalcopyrite, galena, Huang Tie
The mineral intergrowth such as ore deposit and cassiterite, to improve the grade and concentrate indium content of zinc concentrate in ore dressing process, sorting is more in pH>12 height
Carry out in alkali environment, easily poor to the part floatability rich indium marmatite of high alkali environment and fine-particle minerals produce and suppress to make
With the recovery of impact zinc indium.Therefore, the high efficiente callback of rich indium marmatite, always ore dressing how are realized under the conditions of low alkali
The focus and difficult point of worker's research.
The rate of recovery of main metal and rare precious metal in complicated association polymetallic ore altogether is improved, two aspects need to be mainly resolved
Problem, one be improve mog, increase mineral between dissociation degree；Two is to reduce pH values of pulp, though high pH conditions are conducive to
The raising of concentrate grade, but pH is higher, and the rate of recovery of rare precious metal is lower.It is many by changing medicine during actual ore floatation
Agent system and flotation flowsheet are improving main metal and the altogether rate of recovery of association rare precious metal.Such as Qin Wenqing has invented a kind of iron content
The method for floating of zincblende, magnetic iron ore type complex lead-zinc silver sulphide ore（ZL200610136736.7）, by controlling flotation electricity
Change part bar, the branch for carrying out the easily floating galena of coarse grain and silver mineral under higher pulp potential and low ph condition first floats
Choosing, then carries out again the conventional flotation of the difficult floating lead minerals of particulate under the conditions of relatively low pulp potential and high pH, floats the mine tailing after lead
PH values of pulp is adjusted to more than 12 flotation for carrying out marmatite again with lime.Although the method lead silver recovery effect is preferably, iron
The flotation of zincblende is in pH>Carry out in 12 high alkali environment, recovering effect is poor, zinc recovery is relatively low.
Used as a kind of main carriers mineral of indium, there is larger difference in its flotation behavior to rich indium marmatite with common zincblende
It is different, while the quality of zinc recovering effect also directly influences the recovering effect of indium.As in Dachang, Guangxi cassiterite polymetallic sulphide ore
Indium is distributed widely in marmatite, marmatite averagely 421g/t containing indium, and scene is main using " gravity treatment-flotation-gravity treatment " stream
Journey reclaiming the metals such as lead zinc-tin antimony, but because the mineral such as marmatite, cassiterite disseminated grain size is more carefully difficult to dissociate, with gravity treatment work
Skill is that leading beneficiation flowsheet is poor to the recovering effect of indium and fine-particle minerals, through research of technique for many years, zinc indium recovery
Only it is respectively 84.13% and 61.35%.Therefore, how by the leather of mineral processing circuit, System of Flotation Reagent and preparation equipment
Newly, the recovery rate in ore-dressing of rich indium marmatite is improved, it is significant for the indium resource supply for ensureing China.
The content of the invention
The present invention provides a kind of method for reclaiming rich indium marmatite under low alkali from copper zinc indium altogether association polymetallic ore, should
