Abstract
The invention discloses a composite collecting agent for bulk floatation of copper sulfide molybdenum ores. The collecting agent is a stable oily product which is formed by mixing 50%-70% of thiocarbamic acid ester, 2%-10% of thiophosphoric acid ester, 10%-30% of mixed non-polar hydrocarbon oil and 10%-20% of terpene alcohol. The collecting agent has the advantages that the thiocarbamic acid ester has the selective chelation on the exposing active points, such as copper and molybdenum, on the surfaces of minerals, the thiophosphoric acid ester has the selective adsorption function on the copper-containing minerals, the non-polar hydrocarbon oil can be adsorbed on the surface of the copper sulfide molybdenum ores through the Van der Waals force, and the terpene alcohol is a solution medium and has good air bubble property, so under the synergistic effect of the thiocarbamic acid ester, the thiophosphoric acid ester, the mixed non-polar hydrocarbon oil and the terpene alcohol, a good ore selection index can be obtained, and the agent mechanism is simplified; the collecting agent is used at the ore slurry temperature of 5-35 DEG C, and the usage amount is between 80-160g/t according to the change of the contents of usable minerals in the ores.
Description
Technical field
The invention belongs to floating agent technical field, be specifically related to a kind of composite collector of bulk flotation copper sulfide molybdenum ore.
Background technology
Copper sulfide molybdenum ore is the important sources that the mankind obtain copper metal and molybdenum.The fields such as copper is widely used in electrically, light industry, machine-building, building industry, national defense industry, copper is only second to aluminium in the consumption of China YouSe metal material.Molybdenum has the advantages such as high strength, high-melting-point, corrosion-resistant, resistance to barreling, Chang Zuowei produces the additive of various steel alloy, or with tungsten, nickel, cobalt, the senior alloy of the composition such as zirconium, titanium, vanadium, rhenium, to improve its elevated temperature strength, wearability and anti-corrosion property, be widely used in the fields such as aviation, machine-building, national defense industry.The beneficiation method of copper sulfide molybdenum ore, based on floatation, generally uses alkyl xanthate, hydrocarbon ils, ester class etc. as collecting agent.Selective strong during the single use of these collecting agents, required large usage quantity, the preparation in production practices and to add step comparatively loaded down with trivial details.For the copper sulfide molybdenum ore of character complexity, conventional dose system is difficult to obtain good sorting index.Its selective weak and less stable of the more alkyl xanthate of current use, heat, water and acid all can be decomposed, dithiophosphates is only second to a kind of sulfide mineral collector that xanthate is widely used, its collecting ability is more weak, there is foaming characteristic, excessive use can cause foam volume too much, affects floatation process and concentrate quality.Ester class collecting agent is all more stable under alkalescence and acid ore pulp environment, selectivity ratios alkyl xanthate and dithiophosphates good, but its collecting ability is weak, and price is higher.Based on the problems referred to above, propose the present invention.
Summary of the invention
Of the present inventionly be the composite collector that a kind of bulk flotation copper sulfide molybdenum ore is provided.
The object of the present invention is achieved like this: described collecting agent is thiocarbamate, thiophosphate, the nonpolar hydrocarbon ils of mixing, terpenol, is mixed to get stable oil product respectively by 50% ~ 70%, 2% ~ 10%, 10% ~ 30%, 10% ~ 20%.
The copper exposed mineral surfaces due to thiocarbamate in the present invention, molybdenum isoreactivity point have selective chelation, thiophosphate has selective absorption to copper-bearing mineral, nonpolar hydrocarbon ils can be adsorbed in copper sulfide molybdenum ore surface by Van der Waals force, and terpenol is solvent medium and has good foams performance concurrently.The synergy of four can obtain good mineral processing index, simplifies regime of agent simultaneously.This collecting agent uses under the slurry temperature of 5 DEG C to 35 DEG C, and according to the change of valuable mineral content in ore, its consumption is between 80 ~ 160g/t.
