The commonly used collectors for flotation sulfide ore are: Scientific name dithiophosphoric carbonate, of formula is rocssme, wherein r is a hydrocarbon group, me is an alkali metal ion. r is an ethyl group, a butyl group or the like, and is referred to as an ethyl xanthate or a butyl xanthate, etc., respectively. compression fittings 's ring has double anneal,It is much better for seal.compression fittings,Connex compression fittings,Plumbing compression fittings compression fittings,Connex compression fittings,Plumbing compression fittings Taizhou Runde Company , https://www.nerausmotor.com
1. Xanthate includes xanthate and xanthate.
1) Xanthate (xanthogenate). Its structural formula: 
Xanthate is a pale yellow powder. When it contains impurities, the color becomes darker and the specific gravity is 1.3 to 1.7. It has a pungent odor and is easily soluble in water.
The ability of xanthate to collect is related to the length and heterogeneity of hydrocarbon chains in non-polar groups in the molecule.
2) Xanthate ester, the general formula is rocssrËŠ. Commonly used are: ethyl nitrile ester, butyl yellow nitrile ester and the like. It is often used as a sulphide ore collector for copper , lead and molybdenum .
2. Sulfur nitrogens Commonly used ethyl nitrogen, butyl sulfur nitrogen, sulfur nitrogen esters and the like.
The molecular formula of ethyl sulphide is (c 2 h 5 ) 2 ncssna, which is a white powder. It is often light yellow in the industry because it contains a small amount of xanthate. It is easily soluble in water and easily decomposes in an acidic medium. It chalcopyrite, galena collector has a strong ability to capture weak pyrite receive capability.
The formula of thiazolidine is rncssrËŠ. Commonly used diethyl thiazide is a brown oily liquid, hardly soluble in water, soluble in organic solvents, and foaming properties.
3. Thiaminate Sulfur carbamate is a non-ionic collector, slightly soluble in water, amber oily liquid. It is a collector with good selectivity in the flotation of sulfide ore. It has a strong catching effect on chalcopyrite and chalcopyrite and does not capture pyrite.
4. Black drug class i.e. dihydrocarbyl dithiophosphoric phosphate, the formula: r 2 o 2 pssme
Black medicine has foaming properties, and it is not suitable for xanthate, but it is more selective than xanthate, and it is not easy to decompose in acidic medium, and its properties are stable.
1) No. 25 black medicine, namely cresol black medicine (c 2 h 4 ch 8 o) 2 pssh. At room temperature, cresol black medicine is black or dark green viscous liquid, specific gravity is about 1.2, has hydrogen sulfide odor, slightly soluble in water, foaming, corrosive to skin, easy to oxidize and contact with oxygen .
2) butyl ammonium black drug, that is, dibutyl ammonium dithiophosphate, the molecular formula is (c 4 h 9 o) 2 pssnh 4 . White powder, soluble in water, blackened after deliquescence, foaming, suitable for flotation of gold, copper, zinc and other sulfide ore.
3) Amine black drug, the general formula is (rnh) 2pssh. It is used in the production of cyclohexylamine and aniline black powder, white powder, has the smell of hydrogen sulfide, is insoluble in water, and is easily soluble in water-soluble alkali and alcohol solution. Poor stability to light and heat, easy to deteriorate. The amine black medicine has strong ability to capture lead sulfide, has good selectivity, and the foam is not sticky, and the dosage is larger.
4) Sodium type black medicine, the main component is sodium dihexyl dithiophosphate, which is used for flotation of sphalerite, and the lead metal ore collection ability is poor.
5) 208 black medicine, the harvesting ability is stronger than that of sodium black medicine. It is used for flotation of gold, silver and copper mines. It is more effective for collecting fine gold. It is also a copper ore, copper blue and porphyrite. Effective collector.
5. Mercaptans The formula is rsh, which is industrially applied with benzothiazole thiol and benzoimidazole sulphur.
Benzothiazole thiol has a strong ability to capture lead oxide and rivite. In the flotation of sulfide ore, the ability to capture ore is the strongest, followed by sphalerite and the weakest for chalcopyrite. Benzimidazole thiol is mainly used for copper oxide and refractory copper sulfide ore flotation.
6. Thiourea derivatives Diphenyl thiourea (ie, white medicine), the lead of the other party is capable of collecting and collecting, and the ability to collect pyrite is weak.
