Application of a magnetic cyclone on a magnetite dense medium separation process
… on one of the changes that can be made to a dense medium separation cyclone process in order to more efficiently beneficiate coal to meet the specific requirements so that the supply can keep up with the demand. The work done was to determine whether a coarser media could be used in a dense …

Mineralogical effects on the dense medium separation of low grade nickel sulfide ore
Dense medium separation (DMS) is a method often used to upgrade base metal sulfide (BMS) ores before their main processing stage, with varying results achieved for different ore types. The process makes use of the density differences between the BMS minerals and the lower density silicate/carbonate …

Development of an automatic system to monitor the performance of a dense medium (mineral) separation process
Dense Medium Separation (DMS) is a process used extensively in the minerals processing industry to separate dense from less dense material in a dense fluid. It may be considered to be a simple “sink-float” separation process. DMS is used on a large scale in South African coal, iron ore and diamond …

Development of a Multi-Stream Monitoring and Control System for Dense Medium Cyclones
Dense medium cyclones (DMCs) have become the workhorse of the coal preparation industry due to their high efficiency, large capacity, small footprint and low maintenance requirements. Although the advantages of DMCs make them highly desirable, size-by-size partitioning data collected from …

The potential of QEMSCAN in predicting coal washability of Mpumalanga coals
Traditional float and sink analyses are undertaken to determine the washability of coal. Float and sink analyses are costly, require toxic heavy organic liquids and the procedure to wash and dry the float and discard fractions is lengthy. QEMSCAN has the ability to characterise particle density …
