flotation of chromite ore

Process for extraction of platinum group metals from chromite-bearing ore

What is claimed is: 1. A process for recovering platinum group metals from chromite-bearing ores, comprising the steps of: (a) subdividing chromite-bearing ore containing one or more platinum group metals; (b) subjecting a slurry of said subdivided ore to high

In the flotation machine, the slurry after the treatment is treated by mixing and aerating, so that some of the ore grains are selectively fixed on the bubbles. The floating surface is scraped out to form foam products, and the rest is retained in the pulp so as to achieve the purpose of separating minerals.
