Clay minerals have different negative effects on the froth flotation process such as low adsorption of collectors on valuable minerals, increased pulp viscosity, and the reduction in recovery and grade concentrates of copper sulfides. This study aims

Process water used in mineral processing operations corresponds to water recovered from the thickeners and tailings dams, containing residual reagents such as hydrolyzed polyacrylamides (HPAMs). These polymers depress the flotation of different miner

Polyacrylamides (PAM) are used as flocculants in the copper-molybdenum mining industry to improve the settling rate of flotation tailings. These types of reagents are recirculated to flotation in the water that is recovered from the thickeners, and a

Flocculants type polyacrylamide (PAM) plays an important role in mineral processing circuits. It is common practice to reuse water from the thickening stages to other unit operations such as grinding and flotation. In the case of molybdenite flotatio

The effect of a carboxylated polyacrylamide (PAM) of 11.9% of degree of anionicity on molybdenite flotation was previously reported. In this work the depressing effect of a polyacrylamide of 8.15% of degree of anionicity (LPAM) on molybdenite flotati
