AUTOMATION OF TECHNOLOGICAL PROCESSES IN A

The ITI EMAG has been involved in automatic regulation and control of coal preparation processes in jigs since 1980s [6]. There were the PULS heavy medium receivers installed in plants where coal preparation with the use of this method was performed. The users expressed their needs for modern, more efficient devices for machine work control.

The beneficiation of tailing of coal preparation plant

Dense-medium cyclones have been used for beneficiation of fine particles of coal. In this study, the usability of cyclones in the beneficiation of tailings of a coal preparation plant was investigated. For this purpose, separation tests were conducted using spiral concentrator and heavy medium cyclones with the specific weight of medium 1.3–1.8 (g/cm3) on different grading fractions of
