Abstract
In the froth flotation of e.g. mineral ores and coals, the frother agent used is an alkyl, aryl or mixed alkyl-aryl polyoxyethylene ether alcohol or ether or an ether alcohol derived from the condensation of polyoxyetheylene and polyoxypropylene. Preferably the agent is also a detergent and/or wetting agent capable of removing oily layers from collector-coated particles. Examples of the agents are alkyl polyoxyethylene ether alcohols of formula H(CH2)x(OCH2CH2)yOH or alkyl-aryl polyoxyethylene ether alcohols of formula H(CH2)xC6H4(OCH2CH2)yCH, where y is 10 or more di-alkyl polyoxyethylene ethers of formula H(CH2)y(C2H4O)x(CH2)yH where X = 4-30, y = 2-18, and y is less than X, polyoxypropylene-polyoxyethylene ether alcohols of formula H(C3H6O)x(C2H4O)yOH where x = 2-30 and y = 2-60 polyoxyethylene - polyoxypropylene-polyoxyethylene ether alcohols of formula H(C2H4O)x(C3H6O)y(C2H4O)xOH, and polyoxypropylene-polyoxyethylene-polyoxypropylene ether alcohols of formula H(C3H6O)x(C2H4O)y(C3H6O)xOH. Collector agents referred to are xanthates, dithiophosphates, diothiocarbamates, and sales of alkyl sulphates: it is stated that the frother agents are also effective collector acting agents in the flotation of solids possessing low surface energy, particularly coals. The examples relate to the concentration of copper ores containing chalcocite and melachite, lead-zinc ores, and a mixture containing galena.
