Abstract

See full text

A process to treat metal or mineral ores is disclosed. The metal or mineral ore is a metallic sulphide ore including copper, gold, platinum, silver, nickel, molybdenum, arsenic sulphides, cobalt, zinc, lead, tin, antimony, or combinations thereof with a collector composition including a dimeric fatty nitrile. The dimeric fatty nitrile is prepared by a process including reacting a dimer fatty acid with ammonia at a temperature between about 200° C. and about 400° C. to form a dimeric amide and removing water from the dimeric amide to form the dimeric nitrile. The present disclosure also provides a collector composition containing the dimeric fatty nitrile and at least one further collector or frother compound.
