Pulp density is an important process factor in the flotation process, which affects the following techno-economic indicators. 1. Recovery rate. In the flotation of various minerals, there is a clear regularity between pulp density and recovery. When the pulp is very thin

Danafloat

While lime is often used in base sulphide mineral flotation, because excess lime also tends to depress gold flotation, a balance must be maintained between good base metal metallurgy and gold recoveries. Natural pH is recommended for gold flotation. Alternatively using soda ash for pH adjustment can reduce gold depression. Where gold is associated with pyrite in base
