Mining and ore dressing are linked by the dressing grade, which is determined by the average grade of the ore deposits, the head grade and the dilution rate, and which affects both the metal recovery rate and the concentrate grade. Given that the optimal head grade and dressing grade can improve both the utilization of ...
Limitations Of Ore Dressing: Ores are in non-renewal resources. When it is extinct, it takes a long period to form again. Hence it is in limited amounts. Sometimes the process of ore dressing is much more costly than the outcome of the cost from the minerals. Therefore it is uneconomically.
