<p>A process involving the use of a new and improved class of frothing agents in the froth flotation of ores such as the sulfide ores of copper, molybdenum, lead, nickel and zinc, as well as for separating coal fines by flotation. The class comprises the non-hydroxylated ether derivatives of dialkylene glycols such as ethylene glycol and propylene glycol. Especially good results are obtained when these frothers are employed in the treatment of complex copper-molybdenum ores.</p> |
