Utilization of waste coal flotation concentrate for

In this work, the process of copper matte smelting with the utilization of a fine-grained coal-bearing material (the so-called coal flotation concentrate) as fuel is presented. This material is obtained by the process of coal sludge utilization, and, currently, it constitutes an undeveloped waste due to environmental restrictions.

Effect of Collector & Frother Concentration on Copper

2018-5-26  A high frother concentration produces an excessive amount of froth in the flotation cell. This increases the froth overflow and flotation rate, but, unfortunately it also decreases the concentrate grade. Collector concentration has a significant effect (either linear or non-linear) on all three quantitative response variables.
