A leading supplier of mobile and semi-mobile crushing, screening and materials handling products – South African-based Pilot Crushtec – has cornered the silica mining market in South Africa. This is the claim by sales manager Graham Kleinhans, who says there are currently more than ten Twister vertical shaft impact crushers in operation at silica mines in the country.

Kleinhans reveals that more than R2 million has been invested in the purchase of a crusher and screens by the Rebone mine – a highly successful open cast mining operation in the Limpopo province of South Africa which has more than doubled its production in 20 months.

Managed and run by two women – CEO Helen de Bruyn and her managing partner Dinah Mogale – Rebone mine is situated 25 km from Polokwane. It is producing 7 000 tonnes of silica per month, as well as more than 2 000 tonnes per month of aggregate and sand for the construction industry.

Currently the mine supplies 3 000 to 3 500 tonnes per month of 98% silica quartz to ASA Metals for its Burgersfort ferro-chrome operation, 3 000 tonnes per month to Silicon Smelters in Polokwane, and more than 200 tonnes to a business in Delmas.

In the mining process waste is turned into cash in the form of aggregate and sand for the construction industry. Rebone sells about 2 200 tonnes of building stone per month.

“At present we are using excavators to extract the mineral and front-end loaders to place the material for initial screening,” explains de Bruyn. “In years to come we will have to mine the bank, and will then have to introduce drilling and blasting methods, and to use larger crushers to prepare the product for sale,” she adds.

Pilot Crushtec markets its products in more than 25 countries in Africa, Europe, and the Middle East, as well as India and New Zealand.
