In general, the flotation performance of these composites was very good, with high silver recoveries achieved using Potassium Amyl Xanthate (PAX) as the primary mineral collector.
The optimized rougher flotation conditions (Table-3) were: pH of pulp 8.5; grind size of ore 80% passing 100 mesh; the amount of lead nitrate as stibnite activator 300 g/ton; amyl xanthate as a stibnite collector 120 g/ton; pine oil as a frother 30 g/ton; sodium silicate as a gangue depressor 200 g/ton and sodium cyanide as a pyrite depressor 50 g/ton.
Experimental Treatment of Equine Sarcoid Using a Xanthate Compound and Recombinant Human Tumour Necrosis Factor Alpha.
But excess [Na.sub.2]S could depress the flotation because sulfide ions hold a strong reducing capacity [22], thus the potential of mineral/water interface should be reduced, with which the generation of copper xanthate species on the sulfidized mineral surface will be affected.

Cellulose xanthate has numerous applications in various industries, among which mention can be made of its application in floating metals in the extracted mineral rocks.
There are also studies on corrosion protection of aluminum alloy using coatings containing hydrotalcite-bearing organic anions such as benzotriazolate, ethyl xanthate, and oxalate.
Abstract: Mass spectra of reconstructed ion chromatogram (MRIC) technique are used to follow up the grafting copolymerization of 1-vinyl-2-pyrrolidinone (VP) 1-vinyl-3-anisylidine-2-pyrrolidinone (VAP) and ethylmethacrylate (EMA) and cellulose extracted from kenaf using xanthate method.
