Ore Flotation Method
View pageUS Patent:
45307580, Jul 23, 1985
Filed:
Feb 13, 1984
Appl. No.:
6/578990
Inventors:

Kim N. Unger - Tucson AZ
Assignee:
Thiotech, Inc. - Tucson AZ
International Classification:
B03D 114
US Classification:
209166
Abstract:
The method of recovering copper from a copper-bearing ore which comprises froth flotation of the ore in alkaline circuit and in the presence of a phosphorodithio compound of the formula ##STR1## wherein X is hydrogen, alkali metal, or the ammonium radical and R is alkyl-substituted phenyl of from 6 to 14 carbon atoms having from 1 to 3 alkyl substituents and from 1 to 6 carbon atoms in each alkyl substituent. Sodium O,O-bis(isopropylphenyl) phosphorodithioate and O,O-bis(isopropylphenyl) phosphorodithoic acid are illustrative. The method is particularly useful with sulfide minerals, especially with copper sulfides and molybdenum sulfides.
