Pollution of water resources by acid mine drainage (AMD) has been an issue of primary concern in recent decades. This is rooted to the fact that AMD negatively affects the environment and its suitability to foster life. As such, efforts to recover, valorise and beneficiate minerals acquired from AMD treatment process have been ongoing, albeit …

The below Cement Rock Beneficiation Process flowsheet represents a simplified flow diagram of a cement plant in which beneficiation of raw materials is employed. Using a crude feed of limestone and/or clay, the flowsheet produces raw clay by multi-stage cycloning, and "Sub-A" Flotation upgrades the impure limestone.

Beneficiation of the lithium minerals was initially done by hand picking of coarsely crushed run-of-mine but current production involves DMS. In the first stage of DMS, petalite concentrate is recovered in the float fraction. The sinks fraction is reprocessed at a higher media density to yield a spodumene concentrate.
