1.3 Extraction of Platinum-Group Metals From Sulfide Ores. ... The ground matte is separated into three concentrates. Two major methods are used for this purpose: magnetic separation and flotation separation. Matte concentrate destinations vary from smelter to smelter. Residues from the nickel refinery are treated for copper, cobalt and ...

Mar 01, 2016· Platinum-group metals form a complex range of 30 to 40 minerals, each with a different resistance to leaching, making it difficult to find a unique solution for all deposits, explains Eksteen. Once leached, the metals are adsorbed from solution on to activated carbon, he says. The next step is to elute (wash with solvent) metals from the carbon ...

Open-pit mining. Open-pit mining is the activity of removing the earth to access the mineral deposits and continuing to do it vertically in an open-pit. This method is best suited for mineral deposits that are close to the surface of the earth but are not accumulated in a horizontal manner. Open-pit mining often impacts a narrower surface area.

The first step in the mining process is getting the platinum ore out of the ground and into a refinery or processing plant. Two methods exist to extract platinum ore:Inquire Now; Asteroid MiningMassachusetts Institute of Technology. The denser metals in asteroids, including platinum group minerals and REE's, are distributed relatively evenly ...

How Is Platinum Extracted? - Reference. Apr 13, 2020· The platinum ore is not pure, so it is first crushed. This produces many tiny particles that can be treated. Air particles then bubble through an aeration tank and adhere to the platinum particles. This brings the platinum particles, with the air particles, up to the top of the tank.
