"There is no disease in the world. If you can prescribe the right medicine, you will have the principle of "chou", and so is the ore.
For hard rock mineral nature under various complex conditions occurrence, if can do it "right" (the use of advanced technology and beneficiation agents), can greatly improve the recovery rate of ore.
What are the mineral processing chemicals?
The agent referred to herein refers to a chemical additive added to improve the efficiency of the beneficiation process during the beneficiation process. Currently in the field of mineral processing, pharmaceutical processing refers to the main collector, foaming agents, inhibitors, flocculants, agents to adjust, and in hydrometallurgical extraction agent used, and extracted with a matrix modifiers, diluents, etc., each involving Hundreds of inorganic or organic compounds.
Taking flotation reagents as an example, with the poverty, miscellaneous and refinement of resources, the difficulty of mineral flotation is increasing day by day. In order to improve the separation precision of complex symbiotic minerals, flotation reagents are required to have good selectivity. Fine, mud minerals and the quality requirements of concentrates have also prompted the emergence and development of grinding aids and filter aids. The development of filter aids (also known as dehydrators) is particularly rapid. At the same time, the status of environmental protection and ecological environment is increasing, and the requirements for non-toxic and low-toxicity of mineral processing chemicals are also raised.
Mineral processing agent use
Take the following agents as an example:
♦ Ethyl sulfide
Uses: Ethyl sulfide is mainly used as a collector for Cu, Pb, Sb and other metal sulfides. Its collection performance is similar to that of xanthate and black medicine, but it has a strong ability to capture ethyl sulphate compared with xanthate. , fast flotation speed, dosage, high selectivity. It can also be used for metal smelting and purification as well as a promoter in the rubber industry.
♦ Isooctyl thioglycolate
Purposes: as a thermal stabilizer raw materials, mainly for the manufacture of methyl, butyl, octyl tin mercaptide and antimony mercaptide.
♦ Butyl ammonium black medicine
Uses: Butyl ammonium black medicine is an excellent collector and foaming agent for non-ferrous metal ore. It has a special sorting effect on copper , lead , silver and activated zinc sulfide ore and refractory polymetallic ore. It COLLECTING of pyrite and pyrrhotite in weak weak alkaline pulp, and the galena collector strong ability.
♦ Copper sulfate
Uses: Used as a modifier for sphalerite, stibnite, and pyrite flotation.
♦ Sodium ethyl xanthate (potassium)
Uses: It is used as collector of non-ferrous metal easy-floating sulfide ore and complex sulfide ore flotation. It has the best selectivity among yellow medicine series products and is used with vulcanizing agent. It is suitable for flotation of copper and lead oxide ore.
♦ trioctyl phosphate
Uses: It is used as the main solvent in the hydrogen peroxide production process, which can improve product quality, reduce cost and reduce environmental pollution. It can also be used as flame retardant plasticizer for vinyl resin, fiber resin and synthetic rubber, with low low temperature performance. In adipates.
♦ HBF-1 activity of coal sludge flotation agent
Uses: It is compounded by GF oil and other surfactants; it has high selectivity and excellent foaming, fast flotation speed and low dosage; adapt to different coal quality and can be oriented at gas-liquid interface Adsorption and alignment, increase the stability of the bubble, rich in foam layer; it will achieve the best flotation effect when combined with HBB-1 and HBB-2 coal slurry collector.
