Introduction to Mineral Processing or Beneficiation
iv. Froth Flotation – separations based on the surface chemistry properties of a mineral. The natural or modified surface property of the mineral determines its ability to attach to an air bubble and float to the surface. 5.1 Sorting. Sorting by hand has the longest history of all the mineral beneficiation methods and is rarely used today.

Limestone Deposits vs. Beneficiation
Limestone for portland cement must be beneficiated to produce uniform raw material for the kiln. Careful quarrying and selective recovery are factors in this process, but the chief aspects of beneficiation are "in plant" processes, such as crushing and screening, washing, grinding, flotation, and heavy-media separation. Numerous technical and eco-
