Dithiophosphate BS Technical 49%~53%

Dithiosphate BS(Sodium dibutyl dithiophosphate) is gold and silver, copper, zinc sulphide ore flotation effective, basic circuit in the collector on pyrite weak force, the only weak foaming product selectivity Copper sulfide, lead sulfide, nickel sulfide and other multi-Refractory metal mineral flotation has a good effect, widely used in copper mines and associated gold, silver and precious metal mines in the flotation of nonferrous metal.

 Some commercially important xanthate salts include:
sodium ethyl xanthate CH3CH2OCS2Na,
potassium ethyl xanthate, CH3CH2OCS2K,
sodium isopropyl xanthate
sodium isobutyl xanthate
potassium amyl xanthate

Sodium Isopropyl Xanthate Technical

Sodium Isobutyl Xanthate (SIBX) is typically used when the collector needs to be stronger than SEX without compromising too much on selectivity, for instance in some copper-gold, copper-zinc and nickel operations. It is therefore used for flotation of almost all sulphide minerals where high selectivity is not required. It can be successfully applied at flotation of sulphide minerals containing gold, silver or native gold in the process of selective flotation of zinc mineral, after activating of sphalerite or mormolite by copper sulphate.

In some cases, it substitutes PAX (Potassium Amyl Xanthate).

Xanthates in mining

Xanthates have been the workhorse of sulfide mineral flotation since the 1920’s (Harris 1989), and they represent the largest volume of any sulfide mineral collector. Xanthate collectors are salts consisting of a non-polar hydrocarbon group, which provides the hydrophobicity to a sulphide mineral, pointing outward from the mineral to the solution, and a polar group that adsorbs onto the sulphide mineral surface.

Used as an herbicide, fortifying agent for certain oils, and flotation reagent for base and precious metal ores;  Used as a rubber curing agent and antioxidant, pesticide and fungicide, and high-pressure lubricant additive; Also used for analytical procedures, for froth flotation in soils contaminated with mercury, and in the past as an intermediate for saccharin.

Sodium Isoamyl Xanthate(SIAX) is a powerful collector. It is widely used in the flotation processes of nonferrous metallic minerals where a strong but a non-selective collector is desired. It is a good collector for the flotation of oxide minerals, eg.: Oxidized sulfide, copper and lead ores. Copper-nickel sulfide and auriferous pyrite etc also require potassium amyl xanthate as flotation collector.

Sodium Butyl Xanthate Technical 90%,84.5%

Sodium Butyl Xanthate(SBX) is a yellowish or pale grey powder or pellet with a pungent odour, soluble in water and alcohol, It can form insoluble compounds with various of metallic ions.

Sodium Butyl Xanthate(SBX) is a very powerful collector with strong selectivity, widely used in the flotation treatment of sulfide multimetallic ores, especially used in the flotation of natural circuit for copper ores and pyrite, like chalcopyrite, sphalerite, pyrite etc. It is also used in flotation of nickel ores, especially for the flotation treatment of Cu-Ni compound sulfide ore as well as gold mine associated with pyrite. It can also get satisfactory results when used in lead oxide copper ores.

Commonly used in the process of rough flotation and scavenging flotation.
Under the proper conditions, it can be used in the selective flotation of copper sulfide minerals from iron sulfide minerals and in the flotation of sphalerite after activation with copper sulphate.
