Potassium Amyl Xanthate, What is Potassium Amyl

Xanthate is the common name for chemical reagents used in the flotation of base and precious metals, which is the standard method for separating valuable minerals, such as gold, copper, lead or zinc minerals, from non-valuable minerals, such as limestone or quartz (gangue).

01/12/2017  Potassium amyl xanthate (PAX) and sodium isobutyl xanthate (SIBX) are commonly used collectors in both the bulk and selective froth flotation of sulfide ores. These thiol xanthate collectors are conventionally mixed together as well as with more selective thiol collectors such as dithiophosphates (DTP) and dithiocarbamates (DTC), in order to improve selectivity. With deteriorating nickel sulfide

Potassium Amyl Xanthate - Flotation Reagent

Potassium amyl xanthate is a strong 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.

01/01/1976  The long-term tests using potassium ethyl, sodium isopropyl, sodium ethyl, and potassium amyl xanthate indicated that in the flow-through system, the toxicity of the chemicals was in the order of 100 fold greater compared with the static bioassay results. INTRODUCTION The toxicity studies presented here were done in con- junction with a comprehensive study on mine wastes and waste handling procedures for gold mines in the Yellowknife area, N.W.T. The toxicity
