Sodium hydrosulfide also finds applications as a flotation agent
in the mining industry.
In the past, most researches about the recycle and utilization of the copper slag were conducted to optimize the flotation agents
, processes, and procedures in the flotation process of copper recycling [9-11].
The solution chemistry of the various flotation agents
in concentrated electrolyte solutions has never been adequately studied.
Work in progress relates to gold ore processing, the separation of flotation agents
and the treatment of leachates.
