Optimizing the Rougher Flotation Process of Copper Ore
The improvement of the ore and the metallurgical recovery also reduce the total cost of operation per unit, due to a lower cost of the concentrate by dividing the total cost by a higher production. In addition, there are aspects related to the raw material that enters the process, such as the ore grade and the hardness of the incoming rock.
Laboratory Flotation Testing – An Essential Tool for Ore …
platinum ore, for instance, may require 45 minutes to an hour to reach completion and thus the first concentrate can be collected after two minutes of flotation. A faster floating copper porphyry flotation test, however, may finish in five minutes and a first concentrate may need to be collected after 20 seconds.
