Description
Technical field
The invention belongs to mineral separation technical field, specially a kind of to separate recovery sudden strain of a muscle zinc in mine tailing from lead sulfide mixed concentrate
The method of ore deposit.
Background technology
Zinc has important function in national economy as important non-ferrous metal, is mainly used in zinc-plated industry, zinc can and
Many non-ferrous metals formation alloys, the wherein alloy of the composition such as zinc and aluminum, copper, are widely used in die casting；Zinc and copper, stannum, lead group
Into pyrite, for machinery manufacturing industry；Zine plate containing elements such as a small amount of lead cadmiums can be made into zinc-manganse dioxide dry cell negative pole, stamp zine plate,
There are powder corrosion photograph making sheet and offseting printing plate etc.；Zinc fertilizer（Zinc sulfate, zinc chloride）There are promotion plant cell breathing, carbon hydrate
Metabolism of thing etc. is acted on；Zinc powder, Griffith's zinc white., zinc yellow can make pigment.Zinc Oxide can be additionally used in the industry such as medicine, rubber, paint；
For gold is replaced from cyaniding solution in metallurgical industry, the impurity such as copper, cadmium are removed with the net liquid of zinc powder in hydrometallurgy；Zinc is also
Available quantity extracts noble metal in lead bullion etc..
Lead-zinc mine tailings are the main ore types for extracting lead zinc, and ore type is typically complex, except containing lead
Zinc ore beyond the region of objective existence, while all pyrites containing high level, generally using the mixed choosing of lead sulfur separate-select again zinc, diffeential floatation lead-
The mixed choosing of zinc sulfur is separated, after first lead zinc again the principle technological process such as full selective flotation flowsheet of sulfur reclaiming valuable metal therein,
Wherein separate in the mixed choosing of lead sulfur-select zinc technology flow process again, due to sphalerite it is generally embedding with galena and pyrite particulate on a small quantity
Together, therefore in the technological process, zinc can be enriched with the mixed concentrate selection of lead sulfur separates mine tailing, caused for cloth or symbiosis
Part sphalerite is lost in the mixed choosing of lead sulfur and separates in mine tailing.When mining industry is depressed, this part valuable metal is comprehensively utilized, to carrying
The economic benefit of high mining company is more and more important, therefore develops a kind of efficient recycling lead sulfide mixed concentrate separation
In mine tailing, the method for sphalerite seems very meaningful.
The content of the invention
It is an object of the invention to provide a kind of separate the method that sphalerite is reclaimed in mine tailing from lead sulfide mixed concentrate, specifically
Comprise the following steps：
（1）Lead sulfide mixed concentrate separation mine tailing is added water and is sized mixing to mass percent concentration 25%～32%.
（2）In step（1）Sulfur inhibitor Calx is added in the slurry for obtaining, consumption is 1500～2500g/t, adjusts ore deposit
The pH value of slurry is 11～12；After Calx acts on 3～4min, then add activator copper sulfate, consumption is 200～400g/t；Activation
After agent acts on 3～4min, add collecting agent aniline, consumption is 100～150g/t；It is subsequently adding foaming agent, consumption is 35～
45g/t, inflates after 1～2min of effect and scrapes foam, obtain rougher concentration and rougher tailings.
（3）In step（2）Sulfur inhibitor 600～1000g/t of Calx, work are sequentially added in the rougher tailings ore pulp for obtaining
Agent 50～100g/t of copper sulfate, collecting agent 50～70g/t of aniline, frother dosages are 15～25g/t, carry out once purging selection,
Scavenger concentrate and once purging selection mine tailing are obtained, once purging selection concentrate is back to roughly selects operation formation closed cycle.
（4）In step（3）Activator 30～50g/t of copper sulfate is sequentially added in the once purging selection mine tailing ore pulp for obtaining, is caught
Receive 20～30g/t of agent aniline carry out it is secondary scan, frother dosages are that 5～15g/t obtains secondary scavenger concentrate and secondary scans
Mine tailing, secondary scavenger concentrate are back to once purging selection operation and form closed cycle.
（5）By step（2）The rougher concentration for obtaining is milled to ﹣ 0.043mm grain size contents and accounts for more than 90%, is subsequently adding sulfur suppression
Preparation Calx does primary cleaning, and consumption is 400～600g/t, obtains primary cleaning concentrate and primary cleaning chats.
（6）By step（5）The primary cleaning concentrate for obtaining adds sulfur inhibitor Calx to carry out recleaning and obtains secondary fine
Concentrate selection and recleaning chats, the addition of Calx is 200～400g/t；Sulfur inhibitor is added in recleaning concentrate pulp
Calx carries out triple cleaning and obtains triple cleaning concentrate and triple cleaning chats, and the addition of Calx is 200～300g/t, at different levels
Chats order backtracking forms closed cycle, and triple cleaning concentrate is the zinc concentrate for obtaining.
During lead sulfide mixed concentrate of the present invention separates mine tailing, zinc grade is 1.62%-3.02%.
Once purging selection operation of the present invention, it is secondary scan operation, primary cleaning operation, recleaning operation, three times it is smart
It is elected to be the action time of collecting agent and inhibitor in industry and roughly selects identical in operation.
The principle of the present invention：The present invention is separated in mine tailing from lead sulfide mixed concentrate using the technique of flotation and reclaims sphalerite,
It is critical that sphalerite and paragenous mineral（Galena and pyrite）Dissociation, activation sphalerite effectively suppress pyrite simultaneously,
Sphalerite can be floated recovery, reduce the content of sulfur in zinc concentrate, reach the purpose of high efficiente callback.
Foaming agent of the present invention is conventional foaming agent, such as 730A, HCCL, MIBC etc.；Inhibitor, activator, collecting
The dosing mg/t such as agent, foaming agent refers to the medicament of dry ore deposit amount addition m g per ton in selected ore pulp.
Beneficial effects of the present invention：Present invention process is simple, operation facility, invests little, and the response rate is high（The recovery of zinc concentrate
Rate is 80.68%-87.42%, and Zinc in Zinc Concentrates grade is 41.44%-48.16%）, the economic effect of bargh can be effectively improved
Benefit.Meanwhile, the high efficient separation technology of secondary resource disclosed by the invention can be promoted the use of in Pb-Zn deposits select factory, for raising
The level of comprehensive utilization of China's metal, alleviates the pressure of resource, the energy and environment, for promotion china natural resources economizing type, environment
Friendly social construction is also significant.
