metals used in everyday life are produced from ores occurring in the earth’s crust. geological processes are known to concentrate minerals to form ores of economic value. mineral processing engineers concentrate these ores by mechanical and physico-chemical methods while the extractive metallurgist extracts the metals by chemical means.

Infrared Spectrophotometry (IR) is now widely used to determine crystalline silica in industrial dust samples. Though the IR method has many advantages when dealing with respirable dust samples, some serious analytical errors are often caused by interference minerals contamination. These minerals have a characteristic absorption band corresponding in position to the analytical peak for crystall...

The integrated automation system consisting of production process management system, optimal system of production indices and process control system is established for the optimization of production indices of minerals processing. The structure and functions of this system are discussed. The optimal control strategy for production indices is proposed to transform the target of production indice...
