Overview Of Pgm Processing

About 80 of the worlds reserves for platinum group metals PGMs are in South Africas Bushveld Igneous Complex. Processing of PGM involves comminution flotation smelting converting base metals refinery and precious metals refinery. Due to increasing chrome content in the feed and the challenges associated with operating high chrome feed alternative routes to smelting of PGM are being investigated. Some hydrometallurgical routes have been proposed. However none of the reported potential routes have yet been commercialised.

Chemical separation is a highly complex multistage process that converts the five pgms into their final product forms commonly a pgm sponge. It involves dissolution and a series of solvent extractions evaporation precipitation and filtration steps to produce highly pure salts for each pgm. These salts then undergo heat treatment to convert them to the final pure precious metal.

- If any colored salts form upon addition of Ammonium chloride filter them out with a Vacuum System Amazon Link and wash it in the filter several times with x27solution Ax27 until wash solution turns out clear of color.Using a vacuum filter system will reduce this step and further steps down to few minutes and minimize the use of wash solution.Try not to dilute the main liquor too much. The solution now containsmostly Palladium and Ru base metals if present. If too dilute evaporate the solutiondownonce again to a more concentrated volume.

At this point one can choose to re-refine the brick red palladium salt recommended or move on to the conversion step.Converting the palladium salt at this point will most likely produce a final product purity of above 99 depending on starting material. To ensure purity of 99.9 and above a re-refining step is necessary.
