Step 6 Mining samples and determining processing. Once mining gets underway, samples must be taken to determine the precise metallurgical qualities of the ore. This is done in order to determine the appropriate processing technique. Step 7 Processing Once ore is extracted, processing it into pure gold must be done.
Gold ore. Prominer maintains a team of senior gold processing engineers with expertise and global experience. These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and cost efficient process designs.
rare earth element rare earth element Processing ores: All rare earth ores contain less than 10 percent REO and must be upgraded to about 60 percent in order to be processed further. They are first ground to a powder and then separated from the other materials in the ore body by various standard processes that include magnetic and/or electrostatic separation and flotation. In the case of ...
