Condor Dense Medium Separators Sepro Mineral Systems

Condor Dense Medium Separators provide a simple, costefficient way to separate and recover valuable minerals at a coarse particle size, ranging from as fine as 0.5 mm to as coarse as 5070 mm but typically in the range of 1 50 mm. Dense medium separation technology is used for a wide range of mineral separations to produce premium concentrate.

DenseHeavy Medium Separation HMS / DMS Process

HMS and DMS are acronyms for Heavy (Dense) Medium Separation and is applied to the process of preconcentration of minerals – mainly the production of a high weight, low assay product, which may be rejected as waste. In principle it is the simplest of all gravity processes and is a standard laboratory method for separating minerals of different specific gravity.

Dense Medium Cyclone 911metallurgist

From the early 1960's until the mid 1980's, dense medium cyclone circuitry design technology did not change appreciably. The basic design, which was both highly flexible and highly efficient, was consistent with technology developed by the Dutch State Mines ("DSM") in the mid 1940's. During this period, the "typical" dense medium cyclone circuit was designed to process raw coal
