The angular velocity (ω) is often expressed in terms of the rotational speed, N. w = 2πN/60 where w = 60νr/2πr. The centrifugal force, F c, is given by: Fc = mf (2πN/60)2 = mrN2. Centrifugal force is often expressed in the magnitude of the force with respect to the gravitation force (g's):

Mercury is also extensively used in the gold mining process as an amalgam for separating gold from ore. When mercury is combined with gold silt, it causes a reaction that separates the gold from the ore. This amalgam is then heated in order to evaporate the mercury and leave the gold pieces.

 · With the gradual decrease in the grade of copper ores being processed, copper concentrates have become more complex with higher impurity and gangue content. This trend has had a detrimental effect on smelters as they have to increase throughput to maintain copper metal production, while increasing operating costs due to processing the increased amounts of secondary products .

 · Metallurgical processing of metalliferous ores in general and gold ores in particular, consists essentially of three stages, often colloquially referred to as: Bashing (crushing); Mashing (grinding); and. Hashing (extraction/recovery) In the context of flowsheet selection, the bashing and mashing stages are relatively straightforward.

Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation.

Gravity Separation

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 2stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

Dense Medium Separation

Dense Medium Separation

Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrousbased media recovery.
