Platinum is rarely found on the Earths surface and is in fact 30 times rarer than gold. Sources for ore rocks often exist in areas of stream flow in the form of placer deposits. In South America, pre Columbian civilizations found platinum intermixed with gold in river deposits. The largest platinum deposits reside in Russia, South Africa and Zimbabwe, with smaller deposits in Canada and the

In contrast to gold, platinum nuggets are relatively inconspicuous. Refining platinum ore is a costly and laborious process. It can take from eight weeks to six months to process a batch of ore, and it can take up to 12 tons 11 tonnes of ore to produce a single troy ounce of platinum. Once the broken ore is transported to the surface of the mine, it is crushed by machinery into small
Of all the methods of extracting gold processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets.

The first step in the production process is to break platinum containing ore and immerse it in indicator containing water, a process known as 'froth flotation'. During flotation, air is pumped through the ore water mix. Platinum particles rise to the surface in a froth that is skimmed off for further refining.Once dried, the concentrated mixture still contains less than 1 platinum. It is then
03/08/2020· The lifecycle of a gold mine. People in hard hats working underground is whates to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a longplex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit
To extract the platinum group metals from ore, and to refine them process chemistry considered here is therefore based on this system. The normal platinum group metals species encountered are shown in Table I. These species can aquate in weak chloride solutions and water, but this is inhibited in stronger chloride media. Platinum groupplexes are generally much more stable than
Each ounce of gold requires the processing of over 6000 pounds of ore! The gold rush of the mid 19th century expended 125 million troy ounces of gold, worth more than $50 billion by todays standards! The expression go West young man, go West was born from the gold rush in the Western United States. In 1854 the largest gold nugget ever found was in California at Carson Hill above the
