RESOURCES in south africa.
Tiger’s Eye: A silicified form of blue asbestos from the Northern Cape. When polished the gem has a silky lustre with yellow and dark brown bands which reverse in color as the gem is turned. When yellow tiger’s eye is heated it turns red, known as ‚?Bulls Eye‚ and when blueish grey it is called Hawk’s Eye‚. It is polished into beads, buttons and ornaments and
very good value for money.
Lavulite: Also known as Sugulite, it is found only in the manganes mines near Hotazel in the Northern Cape. It is an opaque material with a striking purple colour and is often used as carvings, beads and cabochons. It was discovered in the 1980Р’s and
became very popular in the USA.
Resourses:South Africa is rich in a variety of minerals. In addition to diamonds and gold, the country also contains reserves of iron ore, platinum, manganese, chromium, copper, uranium, silver, beryllium, and titanium. No commercially exploitable deposits of petroleum have been found, but there are moderate quantities of natural gas located off the southern coast, and synthetic fuel is made from coal at two large plants in the provinces of Free State and Mpumalanga.
Diamonds:The 1867 discovery of diamonds in the Cape Colony, South Africa, radically modified not only the world’s supply of diamonds but also the conception of them. As annual world diamond production increased more than tenfold in the following 10 years, a once extremely rare material became accessible to Western society with its growing wealth. The story of diamonds in South Africa begins between December 1866 and February 1867 when 15-year-old Erasmus Jacobs found a transparent rock on his father’s farm, on the south bank of the Orange River. Over the next few years, South Africa yielded more diamonds than India had inover 2,000 years.
Goldmining:Gold mining in South Africa typically involves methods such as panning, sluicing, dredging, hard rock mining, and by-product mining. For most effective gold mining in South Africa, the method used is hard rock mining, since reserves are typically fully encased in rock deep underground. The invention of industrial air cooling and air quality control systems saw gold mines reach unprecedented depths – the deepest being 3 900 metres.This method is accompanied by chemical beneficiation, where chemicals, such as cyanide, or activated carbon are added to rough ore and processed – sometimes with heat, water, agitation, electro-winning etc. Modern gold beneficiation methods can produce gold of 99.9999% purity.
