The Mineral Processing Flowsheets shown on the following pages are based on actual data obtained from successful operating plants. Metallurgical data are shown in these flowsheets which incorporate Crushers, Grinding Mills, Flotation Machines, Unit Flotation Cells, and Selective Mineral Jigs as well as other standard milling equipment. The Flotation Machine, the Selective Mineral Jig and the
Ore reserve estimates include the determination of (1) tonnages of ore and (2) average grade or value per ton. Since the grade or content of valuable metal establishes the difference between rock that may and may not be classed as ore, tonnage cannot be estimated without considering the question of grade.

Flotation. Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic conditionthat is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles
Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing
