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.

Hydraulic method or gravity separation or Levigation: This method is a gravity separation method of metallurgy, which is based on the differences in the gravity of the ore and gangue particles present in the ore. This method is frequently used when the ore particles are more massive than the rocky gangue particles.

Gravity separation, froth floatation and electromagnetic separation methods are physical methods while leaching method is a chemical method of concentration of ores. Gravity Separation – It is based on the difference in the weight of metal and matrix. So, due to gravity the heavier one settled down at the bottom.

The method of metal and graphite inclusions extraction proposed here, provides mechanical or explosive grinding of solid slag to 0–10 mm in dimension, followed by gravity-magnetic and aeration separation of the formed fine slag-metal-graphite mechanical mixture. The process is very time-consuming, costly, and environmentally unsafe (dusty).

Physical separation processes, including blasting techniques, ore sorting, screening, magnetic separation, gravity separation, jigs, may be employed as pre-concentration techniques. Depending on the mineral and specific characteristics of the ore body, a tailored pre-concentration flowsheet may use several devices to prepare the pre-concentrate with the best liberation properties.

All methods of gravity separation work in this manner, but differ in the mechanisms applied to facilitate separation and speed up the process. Centrifugation is the separation method most frequently used in medical settings, but is also occasionally used in more specialized metallurgical operations where small quantities and larger particles are involved.

The previously reported methods of manual separation, gravity separation, high-temperature smelting and slagging refining provide a technical capability to carry out silicon recovery of MG-Si refined slag. However, these methods have drawbacks such as inadequate separation, low recovery rate and high energy consumption.

Gravity Separation . Gravity separation uses differences in specific gravity (SG) between various minerals to achieve a separation, and is normally a wet process although examples of dry gravity separators exist. Gravity separation works best when there is a large difference in the SG in the minerals to be separated, and the particle size is similar

There are several methods for concentrating the ores. The choice of method depends on the nature of the ore. Some important methods are : (i) Gravity separation (Hydraulic washing) : In this method, the light (low specific gravity) earthy impurities are removed from the heavier metallic ore particles by washing with water.

Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
