Abstract
A method for sorting high-slime copper-lead oxide polymetallic ores comprises the steps of preparing flotation ore pulp, performing mixed roughing on copper and lead, performing separation flotation on copper minerals and lead minerals, performing concentration on lead rough concentrates and the like. The invention has the beneficial effects that: the mixed roughing of copper and lead minerals is carried out under the condition of low alkalinity, so that the problems of large floating amount of slime, low enrichment ratio of rough concentrate and low recovery rate of lead minerals caused by high alkalinity of mixed roughing operation are solved; the process of separating copper and lead minerals from the copper-lead mixed rough concentrate directly and separating tailings and then separating lead effectively improves the copper-lead separation efficiency, avoids the problem that the copper and lead minerals are not easy to float upwards in the mixed concentration process, and effectively solves the problem that the slime deteriorates the copper-lead separation and mineralization environment in the closed flotation circulation process of the high-slime copper-lead oxide ore.
Description
Technical field
The present invention relates to mineral floating separating technology technical field, specifically a kind of high mud oxidation copper-lead polymetallic ore method for separating.
Background technology
Common high mud cupric oxide lead ore possesses two features：First ore in broken grinding process easy argillization, clay content is big in flotation pulp, in flotation pulp, -0.074mm grade accounts for 80%, and wherein -0.010mm grade accounts for more than 35%, and argillization is serious；Secondly in ore, oxidation copper content is high, copper mine species are more, mainly includes malachite, chrysocolla, vitreous copper, and copper oxygenation efficiency is 50% ~ 70%；Lead minerals based on galena, Lead oxidation rate 20% ~ 40%.If the efficiently concentrating of copper mineral and lead minerals all cannot being realized in this cupric oxide lead ore using conventional vulcanized sodium, bichromate or sulphite process and separating.The problem existing is embodied in：1 inhibitor amount ranges narrower it is difficult to control, and suppress lead minerals when copper oxide mineral be also easier to be suppressed；2 heavy metal ion are not degradable, and environmental pollution is serious；Add a large amount of floating agents, reagent cost is larger in 3 copper minerals and lead minerals separation process；In 4 concentrate, copper, lead mutually contain severe overweight, and cupric oxide lead minerals is difficult to effectively sort.
Content of the invention
The technical problem to be solved is to provide high mud to aoxidize copper-lead polymetallic ore method for separating, cannot realize the efficiently concentrating of copper mineral and lead minerals and detached problem in this cupric oxide lead ore to solve prior art.
The present invention solve technical problem technical scheme be：A kind of high mud aoxidizes copper-lead polymetallic ore method for separating, and methods described comprises the steps.
