Description
Technical field
The present invention relates to flotation from plumbous many metals of zinc antimony raw ore and reclaim antimony lead and associated silver; The present invention be more particularly directed to a kind of combined capturing and collecting agent and adopt combined capturing and collecting agent to improve the method for antimony lead and associated silver flotation recovery rate.
Background technology
Sangri mining area is positioned at Tibet Autonomous Region Longzi County, is the plumbous zinc multi-metal complex sulphide ore of the ultra-large type base that Tibet Autonomous Region finds up to now; In this region, plumbous many metals of zinc raw ore embedding cloth is related to complexity, and granule size thickness inequality 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 explanation phenomenon in various degree 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, the main feature of poor, thin, the assorted tcrude ore resource that is 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., and therefore effectively improving antimony, the plumbum floatation rate of recovery is the Important Action that associated silver is reclaimed in strengthening.Lot of experiments is studied with practice and is shown, 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 can not infinitely strengthen collector dosage strengthening collecting effect 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 and cannot remain on more than 45%, so not only affects Business Economic Benefit, also increase Product transport cost, directly had influence on the economic benefit of downstream smelting enterprise simultaneously.
For example application number is 201010614789.1, publication number is the Chinese invention patent " a kind of method that improves argillization high-sulfur jamesonite Floatation Concentrate Grade " of CN102218375A, this patent discloses a kind of method that improves argillization high-sulfur jamesonite Floatation Concentrate Grade, the method need to, by adding the specific inhibitors such as tannin extract, improve lead-antimony concentrate grade; Cause floatation process step complexity, and cost of investment is high; And the lead floatingly selecting 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%.
For example 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, this patent discloses the method for floating of the complicated jamesonite of a kind of microfine, comprise that carbon plumbously separates, plumbous mud separates, plumbous sulphur content from; The method need to adopt special separating technology to obtain product; Special separating technology causes flotation cost of investment high, and the lead floatingly selecting 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%.
