Abstract:
The present invention discloses polythiol compositions containing monothiotricyclodecenes, dithiotricyclodecanes, and intermolecular sulfide compounds, as well as mining chemical collector compositions containing such polythiol compositions. Flotation processes for recovering metals, such as copper and molybdenum, from ores using the mining chemical collector compositions also are disclosed.
