Description
Technical field
The invention belongs to ore dressing metallurgical technology fields, and in particular to a kind of pyrite composite inhibitor and its application.
Background technique
Pyrite is almost present in all nonferrous metal sulfide mineral mineral deposits, and the general character that high-sulfur polymetallic ore mountain all suffers from is asked
Topic is the FLOTATION SEPARATION of valuable metal mineral and pyrite, and the quality of separating effect directly affects the grade of main metal concentrate and returns
Yield.
Industrial production is applied and studies more pyrite inhibitor at present, especially in the floatation process of lead zinc sulfide separation
The inhibitor of middle pyrite can be divided into inorganic inhibitor, reductant-oxidant and organic inhibitor three categories.
First, lime, cyanide, vulcanized sodium and other dissolvable sulfides, sulfur dioxide, bichromate, potassium permanganate,
Calcium hypochlorite etc. is all to be using more inorganic inhibitor.Lime is the suppression for the pyrite that current application is most wide, dosage is most
Preparation, be widely used in lead sulphur content from, shallow crust structures, molybdenum sulphur content is from even coal sulfur separating process.Because its is from a wealth of sources, cost
It is the primary selection of the System of Flotation Reagent of sulphide ore containing pyrite that low, floating operation, which requires low characteristic all the time,.Although stone
Ash can effectively inhibit pyrite, but there is also a series of problems in producing, and it is big to be mainly manifested in lime consumption, and must cream processed make
Production technology complicates, and foam is viscous, and entrainment sludge influences concentrate quality more, and the easy fouling of lime, consolidation, blocking pipeline are unfavorable for
Production operation and index are stablized；Secondly, after pyrite is inhibited by lime, difficulty of swimming；In person, lime in ore gold, silver,
The noble metals such as molybdenum have different degrees of inhibiting effect, are unfavorable for the synthetical recovery of rare precious metal.Cyanide is sulfide mineral
Effective inhibitor, since cyanide is extremely toxic substance, and soluble noble metal, no cyanogen, few cyanogen process are current China's lead zinc
The direction of ore dressing development.All there are the drawbacks such as rejection ability or poor selectivity in other inorganic inhibitors.
Second, reductant-oxidant is the suppression realized under oxidation or reducing atmosphere by adjusting pulp potential to sulphide ore
System.Many studies have shown that H under certain condition202, potassium permanganate, potassium bichromate, the oxidants such as bleaching powder can inhibit yellow iron
Mine, inhibiting mechanism are to adjust pulp potential by oxidant pyrite surface oxidation is made to generate hydrophilic substance under oxidizing atmosphere
To inhibit pyrite.SO2, sulphite, vulcanized sodium, the reducing agents such as sodium dithionite can inhibit pyrite, act on machine
Reason is to adjust pulp potential by reducing agent to desorb mineral surfaces xanthate under reducing atmosphere to inhibit pyrite.This kind of inhibition
The amount of the being conference of the shortcomings that agent generates inhibition to galena, zincblende and pyrite, measures few inhibiting effect and insufficient, selectivity
Difference, it is more difficult to use.
Third, organic inhibitor, micromolecular inhibitor mainly have organic carboxyl acid class, nitrogenous class, thiol containing type small by classification
Molecule organic inhibitor；Macromolecular organic inhibitor rejection ability is strong, and the solid type functional group of parent is more, and source is wide, and price is low, nothing
Poison, in production with good application prospect.Sodium humate, polysaccharide kind of starch, sodium lignin sulfonate and polysaccharide xanthates
Class belongs to macromolecular organic inhibitor, and what application was most at present is sodium humate.Either still big point of micromolecular inhibitor
Sub- inhibitor, for the pyrite in different mineral deposits, inhibitory effect differs greatly, at the same there is also selectivity it is not obvious enough or
It is that there is inhibitor effect to the main metal such as lead zinc.In conjunction with the advantage and disadvantage of all kinds of inhibitor, research and develop it is nontoxic, readily soluble,
Affordable and adaptable composite inhibitor and its application method are significant.
Summary of the invention
The first object of the present invention is to provide a kind of pyrite composite inhibitor；Second is designed to provide the Huang
The application of iron ore composite inhibitor.
The first object of the present invention is achieved in that the pyrite composite inhibitor is dimethyl disulfide for amino
Two or more composition in sodium formate, sodium thiosulfate, disodium ethylene diamine tetraacetate and sodium sulfite.
The second object of the present invention is achieved in that the pyrite composite inhibitor for separating the mixing of lead sulphur
Application in concentrate lead sulphur.
The present invention has following exemplary advantage：（1）Composite inhibitor and its application method of the invention inhibits pyrite
Effect is obvious, and small to main metal inhibiting effect, separating effect is significant.（2）Composite inhibitor of the invention is soluble easily in water, configuration,
Addition and flow control are accurate, in process of production, are easy to stablize process and technical indicator.（3）Composite inhibitor of the invention
Dosage is small, performance is stable, pollution-free, it can be achieved that full substitution to lime.
