<p>In an ore-treatment process for the recovery of metal concentrates from mineral ores containing one or more metals in the form of their sulphides and/or oxides, the crushed ore is subjected to a froth flotation process in aqueous medium using, as collector, an ortho hydroxy phenyl oxime of formula <IMAGE> where R is hydrogen or a hydrocarbyl group, R<1> is an electron-donating group, especially an alkyl group, and R<11> is hydrogen or an alkyl, cycloalkyl or aralkyl group. The process is especially suitable for treatment of copper-containing ores but may also be applied to ores containing zinc, platinum, molybdenum, nickel, lead, antimony, arsenic, silver, gold, cobalt, tin and uranium.</p> |
