mineral dressing concentrate:

Mineral dressing (= Orebeneficiation)

Mineral dressing (= Orebeneficiation) The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate ...

Mineral Processing and Ore Dressing

Jun 02, 2016  Mineral Processing and Ore Dressing. Before the event of ore dressing, crude ores were shipped directly to the smelters, or the refineries, with the shipper paying the freight and treatment charges. These charges varied with the type of ore and the distance from the smelter. In all cases they were many times our modem milling costs.

The recovery is 100 percent of chalcopyrite CuFeS2, but the concentrate grade is the feed’s grade, as no beneficiation was conducted. The grade of the concentrate, in this case, is 50 per 1000, which is 5 per 100 of Chalcopyrite. Usually, we need to calculate the valuable element grade rather than the useful mineral
