Flotation Reagents - suppliers, manufacturers, exporters



DENOL-30 is used as a silver promoters in Lead, Zinc Floatation.

Properties Suppliers

GEMPOLYM is widely used as a flocculant to produce liquid solid separation. It is also used in flotation. It acts as a depressant for talc or insoluble gangue mined along with the valuable minerals. It increases the permeability of the filter cake, resulting in an increased filtration rate. It flocculates in an acid environment.

Dithiophosphate BA Technical 95%

Dithiophosphate BA is an excellent collector with frothing performance in flotation of nonferrous metallic minerals. It exhibits specific properties for separating silver, copper, lead and activated zinc sulfide minerals and difficult polymetallic ores. The collective performance of Dithiophosphate BA is weak for the pyrite and magnetizing pyrite, but is strong for the galena in the weak base ore pulp. It is also useful in the flotation of nickel and antimony sulfide minerals and is especially useful in the flotation of nickel sulfide mineral with low flotability, mixture of sulfide-oxide nickel ores and middlings of sulfide with gangue. Dithiophosphate BA is also helpful in recovery of platinum, gold and silver.
The reagent has exhibited weak frothing property. Xanthate with the product instead of floating gold, the gold recovery and concentrate grade and a greater high.

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