How Is Platinum Extracted? Reference

Because platinum is so rare, it must be extracted after being mined through a process that involves crushing it into incredibly small particles and separating these particles from one another. This is known as the flotation separation method, and produces a frothy layer of particles that can be skimmed to provide the extracted platinum.

In the flotation process, these factors also affects the quality of the final concentrate, as for different gold ores, these parameters generally are different it must be determined by beneficiation experiments. There are also many other factors that affect the gold flotation process, such as the water PH, hardness, oxygen content in factory,etc.

Effect of pH on the Recovery and Grade of Base Metal
