Different machines to meet all needs
There are many physical properties of minerals that are testable with varying degrees of ease, including color, crystal form (or shape), hardness, luster (or shine), density, and cleavage or fracture (how the mineral breaks). In addition, many minerals have unique properties, such as radioactivity, fluorescence under black light, or reaction to acid.
Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is .

Summary: In many technical applications, especially in mining and mineral processing, the properties of the rocks play a big role.In many cases, the current mineralogical-petrographic rock characterization permits only a verbal description of the microstructure. In mineral processing, however, this method is not sufficient for certain applications.

Highlights Rheology is important in mineral flotation processing. The mechanism by which the rheology influences the flotation performance is not clear. A reliable method to measure the rheological properties of mineral slurries is not available. Direct correlations between pulp and froth viscosity and mineral flotation performance have been reported.

Introduction to Mineral Processing. The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.
