Description
Technical field
The invention belongs to mineral manufacture field, and in particular to a kind of separating flotation inhibitor of non-molybdenum sulfide mineral, especially
It is a kind of separating flotation inhibitor of the high miscellaneous non-molybdenum sulfide mineral of system and its preparation method and application.
Background technology
Molybdenum is not only the necessary additive of steel alloy, and is indispensable raw material in chemical fertilizer, medicine and human body.This
Outside, molybdenum alloy also has the particularity of anticorrosion antiwear, is usually used in the rail of high-speed railway, the bearing of locomotive, space flight, military weapon etc.
Deng.Molybdenum in China reserves occupy second place of the world, but more than 80% molybdenum ore grade it is relatively low and with the metal such as copper, lead, zinc, tin, tungsten
Mineral intergrowth and association.Floatation is the conventional method of molybdenum extraction, in the FLOTATION SEPARATION mistake of complicated copper, lead, zinc polymetal sulphide ore
Cheng Zhong, because the floatability of molybdenite is preferable, generally use inhibitor suppresses the mode of other metal sulfides by molybdenum ore thing
Separated with other metal sulfides.Contain the difficulties such as a large amount of oily matters, heavy metal ion or clay mineral and select bar in sulphide ore surface
During part, efficiently separating for different metal sulfide mineral can be realized by adding some inhibitor, to obtain molybdenum concntrate product.Therefore,
The depressing agent of suitable non-molybdenum sulphide ore is found, is the key point for realizing molybdenum high efficiente callback.
Have now been found that tens kinds of medicaments have inhibitory action to metal sulfides such as copper-sulphide ores.Chinese patent
(CN106583057A) it is that esterification occurs with chitosan using TGA to prepare thio chitosan mixture as suppression
Agent.Copper mine inhibitor disclosed in Chinese patent (CN106733212A) be received by polyhydroxy xanthic acid, phosphoric acid is received and carboxymethyl three
Thiocarbonate mixes.Chinese patent (CN106179766A) discloses a kind of molybdenum lead separation inhibitor and preparation method thereof
With application, the preparation of the inhibitor is that the Water-soluble Organic Substances containing multiple hydrophilic radicals and carbon disulfide are had into bar in alkali
Reacted and obtained under part.These new inhibitor are developed in existing theoretical foundation and not yet realize work
Industry application.They fail commercialized reason, it may be possible to because industrial significance is bad or prepares expensive.
This is due to that molybdenum ore exists in the form of association or mineral intergrowth mostly in industrial production, and flotation system is sufficiently complex, altogether
Up to tens of kinds of organic substance caused by impure mineral, foreign ion and the ore dressing deposited.And many novel inhibitors all only for
What simple system was researched and developed, the high complexity of actual production flotation system is not considered, it is easy to causes it should in industrial production
With middle failure.
Therefore, widely used still having based on the inorganic matters such as vulcanized sodium, cyanide, nox industrial at present
The inhibitor of wide spectrum meaning.And subject matter existing for these inhibitor is that toxicity is big, waste water is not degradable, recycling water utilization is stranded
