S-Alkyl-, aryl- and -aralkyl-O-alkyl-dithiocarbonates are used as collectors in flotation of complex sulfide ores, especially copper, molybdenum, lead, zinc and nickel sulfide

摘要

S-(1-8 carbon (C)-Alkyl-, aryl- and -aralkyl)-O-(1-18 C alkyl)-dithiocarbonates (I) are used as collectors in the flotation of complex sulfide ores. S-(1-8 carbon (C)-Alkyl-, aryl- and -aralkyl)-O-(1-18C alkyl)-dithiocarbonates of formula (I) are used as collectors in the flotation of complex sulfide ores: R1-O-C(=S)-S-R (I) R11-18C alkyl; R : 1-18C alkyl, aryl or aralkyl.
