【Abstract】 The trial investigation and application of KM-109 in flotation separation of multi-metallic sulfide ores of copper and tin are described. The results show that only by substituting KM-109 for originally-used conventional reagents, the copper grade of concentrate and recovery of copper can be increased by 1.12% and 3.73% respectively without changing the existing process flowsheet.更多还原
