flotation process in platinum production process:

Platinum Mining and Refining Education

In a process called flotation separation, air bubbles are blown through the mixture and carry platinum particles to the surface of the bath. The platinum-rich froth is skimmed from the bath and allowed to dry into a concentrated powder.

The Properties and Applications of Platinum

Aug 21, 2020  The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'. During flotation, air is pumped through the ore-water slurry. Platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining.

How Is Platinum Extracted? - Reference

Apr 13, 2020  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.

Mar 21, 2017  In order to produce one troy once (31.135g) of pure platinum, about 7 to 12 tons of ore must be extracted in a span of six months. The first step in the extraction process is to crush the ore that contains platinum and submerge it in reagent mixture with water. This is called “froth flotation” that uses ore-water slurry to pump out air.
