Gold mining in South Africa

a quarry operator in the libyan needed to expand their crushing and screening

plant in order to cope with an increase in chip and sand demand from the market.

material is granite. they already have one primary and a secondary crusher. material comes out from the impact above 20mm. the

secondary crusher was being operated at very tight settings, but still was

unable to cope with the fines requirements. final products they required is

0-5mm; 5-10mm; 10-20mm (total 3 products). vertical shaft impact crusher

solution after consultation with we mineral’s engineer, they would like to add a

we vsi crusher in the existing plant. this machine will carry the material from

the existing plant of (20-40mm) and reduce it to 0-5mm; 5-10mm; 10-20mm. the we vsi crusher is designed to produce very

good particle shape and a high preparation of fines. after commissioning, the

capacity of up to 150tph easily, which exactly meet the quarry owner’s initial

plan. gold mining in south africa has been the principal focus of black economic

empowerment, resulting in a changing ownership structure. gold mining industry

boomed with the increase in the price of gold and the worldwide economic

slowdown, investment in gold has increased. demand for gold, particularly from

india and china, also increased. up until a few years back south africa was the world‘s

largest gold producer. china surpassed south africa as the world’s largest

producer in 2007. nowdays, gold mining in china, australia and the united states

are also well developed, beside south africa. uth africa‘s main gold mining area

concentrates on the witwatersrand basin, which has produced more than 41000 t

gold in 100 years, and remains the greatest unmined goldsource in the whole

world. to reshape this industry, new projects, technology and approaches to the

organisation of work, some commercial innovations and better labour relations

are already started. the witwatersrand, south africa ‘s most important gold

mine, is a gold placer deposit, unlike most others in the

world. gold mines in south africa host gold by grits and conglomerates. south

africa also have other smaller gold mining places which have gold in the form of

archaean greenstone belts. the main gold producing greenstone belts are the

barberton greenstone belt and the kraaipan greenstone belt. the barberton

greenstone belt is situated in the mpumalanga province, just north of swaziland.

the kraaipan belt is located west of johannesburg, near kuruman. other smaller

belts exist in the northern province, but have been worked sporadically. gold in the rock ore were

very low, in order to extract gold, the ore must be processed by gold mining

equipment. in this process, many gold mining types of equipment are used, such

as gold refining and purifying equipment, but the ore firstly must be crushed

and grinded, thus the gold is separated from the ore.
