Study on intense concentration of gold ore
Cui Yafeng (Henan Provincial Research Institute of Metallurgy)
For concentrating gold intensely, not only the gold occurrence and it'sproperty, but also the features of it's associated minerals should go through full Consideration. As far as gold-bearing ore from quartz vein barren of sulfide and gold-containing oxidized ore from limonite, the preferential process to treat them must be advanced, reliable, rational and economized based on their natures. According to testing, an excelent result was achieved by use respectively of branched flotation, mixed reagent with optimal formula/flotation at variant speed, both butyl xanthate and Sodium hydroximate and stage-grinding-fiolation circuit.
