When used at concentration plants with combined methods of cleaning, the process of dry-concentration at initial stages makes it possible to substract up to 50% of dry final tailings.
The results of concentration of titanium magnetite ores (Kachkanar mining processing plant) using the combined method (impact crushing and dry magnetic separation of crushed material) and the existing method are shown in the table below.
