Gravity separation has been suggested as an alternative to the use of mercury. However, many sites have pyrite and/or chalcopyrite. The gold is embedded in the ore in very fine particle sizes. That is not amenable to grinding using ball mills followed by gravity separation methods such as sluices or cyclonic concentrations.

Spirals AKASPIN are sorting devices which separate materials according to their density differences. They can be used for a grain size range from 60μm up to 2mm, with a throughput per spiral ranging between 1 4t/h. If a higher throughput is required, 2 or 3 spirals can be combined to form one column. The slurry (10% 40% solids ...

The nominal primary grind size was 50um P80. Potassium Amyl Xanthate (PAX) was used as the sulphide mineral collector in the rougher circuit. The rougher circuit pH was maintained at natural through eight minutes of rougher flotation. For Tests 69 to 76 a gravity separation stage, including cyanidation of the gravity concentrate was included.

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.

The gravity separations are simple and separate mineral particles of different specific gravity. As the density of gold mineral is much bigger than gangue mineral, for the gold mine which has gold particles people often use the gravity separation process. Gravity concentration is a proven process for mineral beneficiation.

1. Gravity separation In the rutile ore beneficiation process, there are two main uses for gravity separation: one is for the sorting of rutile ore with coarser grain size, another one is for the tailing work of finegrain rutile, generally used for pretreatment before flotation, which can effectively remove the slime and can remove part of the gangue.

Gravity Spiral Concentrator Working Principle. The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a buildup within that circuit and the eventual escape of some of that gold into the tanks and thereon into the final tails.
