بيت /Reduction Of Flotation Waste From Copper Slag By Zinc
· Copper mineral concentrated after flotation. ... Previously, the compound was tested in a lab setting with minerals containing copper and zinc, and in continuous operation at a miniplant with ores containing copper. It has also been tested for the recovery of copper from waste streams, including mineral tailings and waste slag from metal refineries. Serna and his team now plan to investigate ...

Tailings from flotation of copper slag are a second RCRA special waste. Traditionally, reverberatory furnaces have been the most common furnaces used for smelting, however, they are being replaced by electric or flash furnaces, which are more energy efficient. Reverberatroy furnaces also produce large volumes of low concentration SO2 gas, which is difficult to use in sulfur recovery. The gases ...

· The copper flotation waste (slag) generated from the copper industry is a byproduct from the copper smelting industry [5–8]. The toxicity of the waste is determined by leaching tests and depending on the characteristics of the waste; the spent abrasive must be disposed of as solid or hazardous waste. Owing to the environmental impact of the process and waste management .
