As Platinum is so incredibly rare it can take about as much as 10 tonnes of ore to find one ounce of Platinum. There are several steps in the mining process of Platinum, the first one being extraction of the Platinum ore and bringing it above ground, there are two ways of doing this the first and older way is to blast the ore free with explosives.
2 #0183;#32;Titanium processing Titanium processing Extraction and refining: The production of titanium metal accounts for only 5 percent of annual titanium mineral consumption; the rest goes to the titanium pigment industry. Pigments are produced using either a sulfate process or a more environmentally acceptable carbochlorination process (described below) that converts TiO2 into TiCl4.

most sophisticated industrial inorganic chemistry: refining of platinum group metals ore concentrate. pgm ore concentrate The figure below shows a typical assay of a South African platinum group metals ore concentrate obtained as the filter cake after sulfuric acid leach (according to the Sherrit process) of a Merensky reef converter matte.

The recovery of metals from sulfiderich ore bodies proceeds through a series of steps: from mining to crushing to mineral recovery (, concentration), followed typically by smelting of the sulfide concentrates and thence to metal refining; although the nature of the ore body dictates the processes used to extract metals from ores, each of these steps generates a waste stream.
9 Step Process for Discovering, Mining amp; Refining Gold. By ProvidentMetals on January 23, 2012 Filed Under: Refining (offsite) Once basic the process of taking metal ore from the earth and converting it to gold bullion is quite extensive and requires a lot frontend investment and time.
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.
Before the advent of heavy machinery the raw ore was broken up using hammers wielded by hand, a process called quot;spallingquot;. Before long, mechanical means were found to achieve this. For instance, stamp mills were used in Samarkand as early as 973.

Platinum mining, however, differs from gold mining in different ways. PLATINUM REFINING AND ISSUES : 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''.
#0183;#32;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
A major development in the worlds platinum industry took place in the early nineteen twenties when large deposits of platinum bearing ore were discovered in the Transvaal in South Africa. This led to the formation in 1931 of Rustenburg Platinum Mines Limited to work these deposits, and this company remains to this day the only platinum producer in South Africa and the only major producer in
