    摘要: A process for the recovery of minerals from an ore or concentrate containing the same wherein the minerals are recovered in a froth from an aqueous pulp containing the ore or concentrate and wherein one or more mineral flotation agents are employed in the aqueous pulp to control the type of minerals in the froth is provided. The mineral flotation agents used in carrying out the process comprise compounds formed by the addition of hydrogen sulfide to dicyclopentadiene. In one embodiment, the mineral flotation agents used in carrying out the process comprise tricyclodecenyl mercaptans having one or both of the following structures: ##STR1##
