Abstract:

According to the flotation for low grade oxidation metal ore and oxysalt metal ore,we put forward a sulfuration technique of polysulfide ions.The research shows that there is more oxidizing and chelating power for main group metal and sub-group metal which exclude alkali and alkaline earth metal than for single sulfides ions in magma,with S52-and S42- as the polysulfide ions curing agen which is the main sulfides ion portion,ulteriorly the ions form polysulfide ions complex.In the acid,neutral and alkaline solution,the polysulfide ions complex will adhere to the target ore and the mineral surface tightly that they shape the extrusion cladding of polysulfide ions sulfide,creating necessary and sufficient conditions for recycling the low grade oxidation metal ore and oxysalt metal ore efficiently.

Key words: polysulfide ions, sulfide, extrusion cladding, sulfuration technology
