Platinum Refining Process
Platinum scrap such as platinum coins, palladium PD and platinum wire is weighed and then smelted. As the platinum scrap liquefies in the furnace or melts under a blowtorch, flux is mixed in to separate the pure platinum from other precious and non-precious metals. A sample is removed for assaying, which is the process of measuring the platinum ...
Problems in the mining industry in South africa
The current turbulence in the mining industry in South Africa has its roots in several different factors. First, the fall in global demand for platinum and other minerals due to recession; second, the consequences of the Marikana disaster in destabilising labour relations; and third, the structural character of our mining industry. A great deal has been written about the first two factors, so ...
Methods of Metal Recovery by Microorganisms (2 Methods)
For optimal extraction of uranium by bioleaching, the ideal conditions are temperature 45-50°C, pH 1.5-3.5, and CO 2 around 0.2% of the incoming air. The soluble form of uranium from the leach liquor can be extracted into organic solvents (e.g., tributyl phosphate) which can be precipitated and then recovered.

The recovery of platinum, palladium and gold from acidic feed solutions which contain chloride ion is accomplished by first using a substituted 8-hydroxyquinoline reagent or a derivative thereof for extraction wherein a chelate is formed between the reagent and the precious metals.
Live Resin: What Is It And Why Is It So Awesome?
The extraction of live resin begins immediately after the plant is cut from its growing medium. Once cut, the plant begins to lose terpenes almost immediately. In fact, normally-processed plant material (i.e., dried and cured) can decrease in terpene content by as much as 60% before it …
Copper Mining and Extraction Sulfide Ores
Gold, silver, platinum and tin are insoluble in this electrolyte and so do not deposit on the cathode. They form a valuable ''sludge'' that collects under the anodes. Soluble impurities of iron and nickel dissolve in the electrolyte, which has to be continually purified to prevent excessive deposition onto the cathodes, which would reduce the ...
