between velocity and density have long been acknowledged and therefore it is considered that the modeling of density variations with gravity data will enhance the velocity model where uncertainties exist. We apply a direct model to density computed from velocity for a seismic dataset recorded offshore Suriname.

Gravity concentration is at present the main concentration process in the mineral industry in terms of tons processed. The size that can be processed ranges from very coarse materials, coarser than 100 mm, concentrated through heavy media vessels or ROM jigs, to very fine particles, about 10 microns, concentrated through centrifugal processes. ...
It is generally accepted that gravity concentration is the most simple and economical of all methods of concentration, permitting the recovery of values at as coarse a size range as possible. In essence, mineral particles are separated by virtue of the differences in density - the greater the difference in density between two minerals, the more ...

Our mineral gravity concentrators separate fine heavy mineral particles from 1.5 to 0.04 mm, and are ideal for iron ore, chrome, mineral sands and high density ores. Their compact nature and relatively low height provides a low footprint classification solution. These gravity concentrators can be assembled in high-, medium- and low-grade ...
Gravity concentration process which exploits the differences in densities of minerals to bring about a separation, is the oldest beneficiation method known to mankind. Although with the …
Gravity concentration, or density-based separation methods, declined in importance in the first half of the twentieth century due to the development of froth flotation, which allowed for the …
In another example, Newcrest Mining of Australia introduced enhanced gravity concentration to treat flash flotation concentrate at the 50,000 tpd Cadia Mine in Australia in 1997. This flash flotation concentrate was then treated with a Falcon Concentrator, where the resulting gravity concentrate was upgraded for smelting on a shaking table.
