Results obtained from this work show that chitosan polymer has a promising future as a biodegradable alternative to sodium cyanide for the purpose of depressing pyrite in sulfide minerals flotation 1 Introduction Froth flotation has found extensive use in the mineral processing industry especially in treating low grade or
The most popular method of separation is the froth floatation method, which was specifically designed for sulfides as opposed to smelting which is more suitable for larger veins of metal ore Another more modern method uses microorganisms to separate the metals from the sulfur
The sulfide ores are usually processed using the method of pyrometallurgy a process of extraction and purification of metals which involves the application of heat in four major steps: 1 froth flotation to separate the copper minerals from the gangue, 2 thickening stage ,
This invention is directed to the use of non-sulfur containing compounds as collectors in the froth flotation of certain mineral sulfide and metallic compounds These non-sulfur-containing compounds may be from natural sources, such as vegetable oils, or synthesized commercial sourc These non-sulfide collectors can be used singularly, in combinations, and in mixtures with known commercial .
