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.
Platinum, along with the rest of the platinum-group metals, is obtained commercially as a by-product from nickel and copper mining and processing. During electrorefining of copper, noble metals such as silver, gold and the platinum-group metals as well as selenium and tellurium settle to the bottom of the cell as "anode mud", which forms the starting point for the extraction of the platinum ...
Mining of the UG2 at Western Platinum Mine commenced in 1982, and the UG2 concentrator started up in March 1983. The UG2 ore is generally milled separately from the Merensky ore. More than 75 per cent of Lonmin Platinum's current annual production is sourced from the UG2.
However, the overall platinum mining process is labour and capital intensive taking half a year or more and 12 tons of ore to produce one troy ounce (31.135 g) of pure platinum.

2019/12/08· The good news is that not all platinum is produced from primary sources in this long and expensive process. According to United States Geological Survey (USGS) statistics, about 30% of the 8.53 million ounces of platinum produced worldwide in 2012 came from recycled sources.
2018/01/28· Learn all about platinum as a precious metal, and the centuries long processes of mining and refining that have made it so integral to many parts of the world. Enjoy a detailed discussion on the history of platinum mining and refining, including facts, figures, pictures and charts to help explain.
Mining as an industry underwent dramatic changes in medieval Europe.The mining industry in the early Middle Ages was mainly focused on the extraction of copper and iron. Other precious metals were also used, mainly for gilding or coinage. were also used, mainly for gilding or coinage.
Platinum mining in South Africa In South Africa, the discovery of the first platinum nuggets dates back to 1924. The geologist Hans Merensky's follow-up work resulted in the discovery of two deposits, each around 100km in length, which became known as the Bushveld Igneous Complex.
