The Merensky Reef was the principal source of pgm from the time that it was first worked in 1925 until the end of the 20th century. However, extraction of other reefs has grown in importance, and by 2011 the Merensky Reef accounted for only 22 per cent of all the platinum ore processed in South Africa. Exploitation of the UG2 began in the 1970s

It is carried out extensively at all copper refineries, both on blister copper and on the cathodes produced by electrolytic refining. The different sorts of blister copper are susceptible to extensive furnace refining, but the melted cathodes require it in slight degree only and that largely for the exact regulation of the final oxygen content of the metal.
Alloyed copper, containing slight [Show full abstract] additions of different elements and having special physio-chemical properties, is used in a special range of applications.
Also, properties of the materials researched, and, at the after introducing into deoxidized copper the additions same time, their strength properties, of chromium (0,8 %) and nickel (2,1 %), and casting the applying modifying treatments causes slight im- initial samples, the varied additions of silicon were ad- provement in the degree of grain size-reduction, ministered, in the amounts ranging from 0,4 to 2,2 %.
The percent of oxygen in the copper melt after refining was determined as between 0.2 to 1.0 and generally between 0.4 to 0.7. I have found that there is a slight effect on the distribution coefficient based upon the oxygen level and that D Pb is maximized at an oxygen level of between 0.6 to 0.8. However, since the effect is small, the actual preferred oxygen range may be somewhat different for reasons
In the gunite mixtures applied to the brickwork of the slag belt on the back wall of the copper-refining furnace, we found only slight transformations, whereas in the samples from the front wall these changes were considerable; this shows the strong slag corrosion of the refractory brickwork of the front wall.
Typically, in the case of copper, the copper scrap to be purified is melted in a refining furnace to a temperature in a range of about 1120° to 1150° C. and oxygen is added to the melt to increase the oxygen content thereof. The desired slag components are then added to the molten metal so as to form a molten slag composition thereon.
Refining effects were estimated by comparing the effectiveness of micro structure changes with property changes of copper and its selected alloys from the group of tin bronzes. View Show abstract

Smelting and refining steps cause a higher impact for aluminium, ferroalloy, nickel, and manganese mining which are due to the significant amount of electricity consumed in the smelting operation. From the discussion presented above and in Table 17,it is quite evident that most of the environmental emissions from mining industries are due to electricity consumption and fossil fuel usage, whatever the process is.
Mining and Refining Process. The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. Alumina
Mining and Refining Energy Efficiency. Globally, and despite declining ore quality, the alumina refining industry reduced the energy intensity of its operations by 9% between 2006 and 2010, while increasing production by 15%.
