A concise flow diagram of the copper flotation process can be shown in Fig. 1.Raw ore is firstly conveyed to the ball milling. Next, the ball milling breaks the feeding ore into pulp slurry with a suitable particle size (minerals size should be under 200 mesh, i.e., less than 0.074 mm).Eligible slurry from ball milling is then fed into an agitated tank, …Web

The SX/EW Process. The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal.
