Gravity concentration is the separation of minerals based on differences in specific gravity A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact Gekko Systems
Ore concentrate Ore concentrate, dressed ore or simply concentrate is the product generally produced by metal ore mines The raw ore is usually ground finely in various comminution operations and gangue (waste) is removed, thus concentrating the metal component The concentrate is then transported to various physical or stone processes
The average estimated concentration is between 55 and 70 mg/kg, placing it below chromium (200 mg/kg) and zinc (132) but above tin and lead Commercially exploited deposits of copper ores are found in many parts of the world, frequently associated with mountain-building processes
The concentrations of prealbumin and transferrin in most CSF specimens, and the concentration of immunoglobulin G in some of the multiple sclerosis CSF specimens were higher than would be expected on the basis of the molecular weights and the concentrations in serum; 2 the concentration of gamma-trace protein in CSF was also considerably
