Beneficiation agents what are the commonly used types
The emergence of mineral processing reagents is the inevitable outcome of human development progress. It have solved the problem in people daily life for a long time many of the problems, and greatly improved the work efficiency of people, will be referred to a better level of people's lives. Below is we introduce you to the commonly used types of the mineral processing reagents.
A, flotation reagents
1, butyl xanthate: light yellow, soluble in water, ten months shelf life, content of 84.5% or more, free alkali < 0.5 sufficient alkali (no response) it is made of sodium alkali, carbon disulfide, butanol reaction synthesis, used in weak alkaline pulp, collecting ability is stronger, is applied to all kinds of non-ferrous metal sulfide ore flotation.
2, isoamyl xanthate: yellow, soluble in water, the shelf life for 10 months, content of 79% or more, free alkali < 0.5, it is made of sodium alkali, carbon disulfide, synthesis of isoamyl alcohol response, powerful collector, is suitable for the need to collecting power, without the need for selective flotation of non-ferrous metals (such as copper oxide is difficult to choose the mineral).
3, ethyl xanthate: light yellow, soluble in water, the content is 82%, the period of validity for ten months, it is made of sodium alkali, carbon disulfide, ethanol is synthesized, collecting ability is weak, strong selectivity, suitable for easy floating or complex metal sulphide ore flotation.
4, b sulfur nitrogen: gray crystals, soluble in water, the content is 95%, valid for one year, it is synthesized from diethylamine and carbon bisulfide reaction, than xanthate, black powder collecting ability, fast flotation, the dosage, can be used in the high alkaline pulp, applicable to such as lead, antimony, copper sulphide ore flotation.
5, ding ammonium aerofloat: white powder, very soluble in water, the content is 95%, valid for two years, it is made of butanol, phosphorus pentasulfide, ammonium reaction synthesis gas, chemical stability strong, can obtain good collecting effect in acid pulp, galena, nickel, antimony collecting ability is stronger, especially metal sulfide ore containing platinum, gold, silver and other pesticides, favorable platinum, gold,
Second, the foaming agent
No. 2 oil (pinitol oil) content is 39%, light yellow oily liquid, valid for two years, it is composed of fusel oil and alcohol oil blending, suitable for all kinds of non-ferrous metals and coal flotation.
Third, adjust the agent
1, sodium sulphide: a variety of purposes
(1) inhibitors (2) to take off the reagent 3) activator
2, sodium sulfite,
(1) reducing agent (2) inhibitors: inhibition of sphalerite and pyrite
3, zinc sulfate, zinc blende inhibitors, must be Shared with alkali have inhibition.
4, copper sulfate, activator
5, sodium carbonate: adjust the pulp acidity of silver recovery, ammonium butyl foamability, foam thick big brittle.
6, 25 black: black aqueous solution, slightly soluble in water, the content is 53%, valid for two years, it is made of cresol, phosphorus pentasulfide reaction synthesis, is suitable for the flotation of copper, lead sulfide ore, slightly soluble in water so to add in the ball mill or adjust the groove.
7, Z200: amber oily liquid, slightly soluble in water, the content is 95%, shelf life two years, it is composed of isopropyl xanthate, fat, good selectivity, and is suitable for the need of high concentrate quality of non-ferrous metal.
