Improving Flocculation Performance of Copper Flotation
However, the tailing slurry containing roughly 40–60% solids is discharged as a result of the process (Bleiwas, 2012). The primary environmental issues with copper mines are the disposal and dewatering of these tailings. Impurities such as heavy metals, chemical reagents, and fine particles are present in flotation slurries.
