More than 40%.China turns into International Lead, zinc major producing country and country of consumption.At the same time, industry is thrown in technological progress, industry
The diversification of money main body, enterprise implement go-global strategy etc. all achieve prominent achievement, in recent years, due to lead, zinc smelting
Enterprise's production capacity overdistension is refined, causes raw materials requirement amount to surge.China is changed into net importer from lead, zinc raw material net exporter.
Particularly large-scale key smelting enterprise is to the interdependency more and more higher of external lead, zinc concentrate, and there is lack of raw materials has become system for lead zinc
The about bottleneck of Lead for China Zn Cr coating sustainable development.
From the point of view of the consumption in China, Lead for China, the zinc deficiency and excess coming years will appear from the situation that supply falls short of demand.
With lasting increase of the China to the demand of non-ferrous metal, it is available for the high-quality Pb-Zn deposits of exploitation fewer and fewer, only
The complicated mine of recovery lean ore, oxide ore, structure construction can progressively be exploited.Traditional beneficiation method is difficult processing to such raw ore
And recovery, the wasting of resources is caused, is badly in need of handling such ore using the flow and regime of agent of optimization.
The content of the invention
The deficiency of actual and existing flotation technology is exploited for complex lead zinc ores, the present invention is mainly just to provide one kind and carried
The method of high complex lead zinc ores flotation recovery rate.Mainly following methods and the step taken：
(1) by raw ore ore, the target mineral monomer cleavage of the embedding cloth of coarse grain is ground to by primary grinding；
(2) by cleavage and the lead-zinc sulfide ore thing of the fast embedding cloth of coarse grain of ascent rate, according to roughing froth pulp
Grade and flexibly determine directly to go out concentrate product containing miscellaneous situation, be also into and selected a certain sort section；
(3) the slow lead-zinc sulfide ore of ascent rate and part and the oxide ore order of sulphide ore adhesion are entered into selected stream
Journey；
(4) the thin and traditional sulfide flotation medicament of those disseminated grain sizes effectively the oxygen of flotation recovery, sulphur can not be mixed
Ore deposit is reclaimed by the method for administering drug combinations (adding oxide ore and sulfide flotation medicament simultaneously in proportion)；
(5) froth pulp of step (4) is entered into cleaning technological flowasheet after secondary grinding；
(6) secondary grinding of step (5) is divided according to difference of the raw ore fine-grained disseminated grain partial target mineral between individual grade
Regrinded for open circuit and regrind two kinds with closed circuit.
The floatation process method of the present invention, compared to existing traditional handicraft, has following major advantage：
(1) ore different to disseminated grain size in same ore, by ore grinding twice, progressively cleavage can both reduce ore grinding energy
Consumption, and can prevent overground and argillization；
(2) concentration times of different foam product are determined according to the difference of flotation speed, middling cycle amount can be reduced, carried
High-recovery；
(3) by scanning combine add oxide ore flotation medicament, can partially recycled oxide ore, can synthetical recovery oxidation
Sulphide ore and oxide ore of the rate in 15% or so lead zine ores.
(4) lead zinc recovery can be greatly improved 5-10 percentage points by the method for floating of this technique, produce good economy
Benefit.
