Description
Technical field
The present invention relates to flotation from plumbous zinc antimony many metals raw ore and reclaim antimony lead and associated silver; The present invention be more particularly directed to a kind of method adopting combined capturing and collecting agent to improve antimony lead and associated silver flotation recovery rate.
Background technology
Sangri then mining area is positioned at Tibet Autonomous Region Longzi County, is the plumbous zinc multi-metal complex sulphide ore base of ultra-large type that Tibet Autonomous Region finds up to now; In this region, the embedding cloth relation of plumbous zinc many metals raw ore is complicated, and granule size thickness is uneven, belongs to complex refractory ore.In ore, main antimony mineral is boulangerite, jamesonite, and galena, stibnite are few; Zinc mineral is mainly zincblende; Silver mineral is mainly silver-colored antimony tetrahedrite.Jamesonite, boulangerite have corrosion in various degree to hand over phenomenon to galena, zincblende, pyrite, monomer dissociation difficulty, therefore current output lead antimony compound refined mine and zinc concentrate.
Along with mineral resources are exploited in a large number, poor, thin, assorted is the main feature of the tcrude ore resource of current exploitation.In this raw ore, jamesonite is compared with galena, have the advantages that disseminated grain size is thin, floatability is poor, and silver mineral is except main silver-colored antimony tetrahedrite, the main carriers mineral of other associated silver are boulangerite, jamesonite and galena etc., therefore effectively improve antimony, the plumbum floatation rate of recovery is the Important Action that associated silver is reclaimed in strengthening.Lot of experiments Researching and practicing shows, in this raw ore, boulangerite, jamesonite are to flotation pH value sensitivity, and experimental study is consistent with production practices to be shown, this raw ore of flotation is more suitable under the condition of neutral pH=7.0 ~ 7.5, and plumbous antimony flotation recovery rate is higher
;owing to containing a certain amount of zinc mineral in raw ore, therefore collector dosage strengthening collecting effect can not infinitely be strengthened in preferential floating plumbous antimony operation, say again, if excessive collecting agent pours in the selected operation of plumbous antimony, its lead-antimony concentrate grade is by uncontrollable, and lead adds antimony grade cannot remain on more than 45%, so not only affect Business Economic Benefit, too increase Product transport cost, directly have influence on the economic benefit of downstream smelting enterprise simultaneously.
Such as application number is 201010614789.1, publication number is the Chinese invention patent " a kind of method improving argillization high-sulfur jamesonite Floatation Concentrate Grade " of CN102218375A, which disclose a kind of method improving argillization high-sulfur jamesonite Floatation Concentrate Grade, the method needs, by adding the specific inhibitors such as tannin extract, to improve lead-antimony concentrate grade; Cause floatation process step complicated, and cost of investment is high; And the lead floatingly selected adds that antimony grade is the highest can only arrive 48.03%, lead adds that antimony recovery is the highest can only arrive 77.34%.
Such as application number is 201310413919.9 again, publication number is the Chinese invention patent " method for floating of the complicated jamesonite of a kind of microfine " of CN103433142A, which disclose the method for floating of the complicated jamesonite of a kind of microfine, comprise that carbon lead is separated, plumbous mud is separated, plumbous sulphur content from; The method needs to adopt special separating technology to obtain product; Special separating technology causes flotation cost of investment high, and the lead floatingly selected adds that antimony grade is the highest can only arrive 43.5%, and lead adds that antimony recovery is the highest can only arrive 66.12%.
