Dense Media Separation | DMS | HMS

Description. Dense media separation (DMS for short) is a widely used in the mining industry by densitometry errand valuable minerals and non-valuable rock separation process. The process can be conducted at particle sizes as coarse as 300 mm and as fine as 500 μm with high separation efficiency, depending on the liberation characteristics of ...

Mineral Processing

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

Laboratory Jigging Equipment. The jigs in use for water-sorting are plunger-jigs and movable sieve-jigs. The former are represented by two Collom jigs [10 and 11 and Fig. 3], used for ores ranging from 30- to 5-mesh, the latter by a Richards jig [17] for sizes larger than 5-mesh. The Collom jigs are two-compartment machines.

Different types of separation methods for minerals

Mineral processing is the first step for ore once it leaves the mine. The process involves ore preparation, milling, and ore dressing, commonly known as beneficiation. Beneficiation mechanically separates the grains of ore minerals from the gangue (low-value) minerals that surround them in order to produce a concentrate made up of useful minerals.

Jigs and Fixtures: Types, Parts, Definition, Applications

A fixture holds and positions the work but does not guide the tool. Whereas a jig holds, locates and as well as guides the tool. The fixtures are heavier in construction and are bolted rigidly on the machine table. Whereas the jigs are made lighter for quicker handling, and clamping with the table is often unnecessary.

Gravity Separation

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.
