Parametric Optimization in Rougher Flotation Performance

Flotation experiments were conducted in a Denver type agitated flotation cell at the rougher stage. The experimental results showed that increasing the pH (from 8 to 10) at low agitation rate (1000 rpm) enhanced the recovery from 80.36% to 85.22%, while at high agitation rate (1200 rpm), a slight declination occurred in the recovery.

Parametric Optimization in Rougher Flotation

The dominant challenge of current copper beneficiation plants is the low recoverability of oxide copper-bearing minerals associated with sulfide type ones. Furthermore, applying commonly used conventional methodologies does not allow the interactional effects of critical parameters in the flotation processes to be investigated, which is mostly overlooked in the literature.

Flotation of Copper oxide ore - Fodamon Machinery

The floatability of copper oxide ores is generally worse than that of copper sulfide ores, and is greatly influenced by the existing form of copper in minerals and gangue composition. For example, when copper is in the form of carbonate (malachite, blue copper ore), the flotability is relatively good, while the flotability of silicate (silica malachite) is poor, free copper
