RECENT DEVELOPMENTS IN PRECONCENTRATION

2016-5-22  Dense media separators are commonly used for preconcentration of coal and diamonds but less commonly for other mineral systems such as lead and zinc. Due to lower head grades adding to the complexities of the ore, multi-stage dense media separators like the Condor can offer some advantages over the single-stage dense medium cyclones.

Coal Processing - Multotec

Following sizing, coarser coal is fed to a Dense Medium Separator (DMS) drum or a Large Diameter Dense Medium Cyclone. If a dense media drum is used, the intermediate size fraction reports first to a desliming screen followed by the dense medium cyclone which is more suitable to process the smaller size fractions effectively.

Dry - Dense Medium Separator - Leading Products -

Dry dense-medium separation technology is a kind of high-efficiency dry-medium separation technology based on gas-solid fluidized bed. It has high sorting precision and can not effectively separate 6-100mm coal. On the outside of the larger water of raw coal, dry and dehydrated after separation, to achieve dehydration, sorting double quality.

Field Testing of a Zero Offset Dense Medium Separator

The density gauges already in use in all dense medium cyclone plants provide a reliable mearsurement of circulating medium density. If a cyclonic separator could be made to separate efficiently at the feed medium density - that is, with a zero offset - the problem would be overcome in a cost effective manner by the retrofitting of such separators.

LARCODEMS Separator — Development of Three-product

Coal Preparation Engineers at British Coal Corporation’s Technical Services and Research Executive (TSRE) developed the world’s largest centrifugal dense medium separator, the LARCODEMS, capable of treating up to 250t/h of 100–0.5mm raw coal. The first production plant was commissioned in 1986 and a number of plants are now in operation.
