Curing a serious environmental hangover

Acid Mine Drainage (AMD) in South Africa explained Mining first started on the Witwatersrand just over 120 years ago. As the surface reserves got depleted, miners were forced to start digging.

This has led to a vast network of underground tunnels, resulting in a large void. As the mines started to close down, the water table began to return to the level it was before mining started. As the mines closed down, the pump stations were turned off and that void became flooded with water. As a result, mineral rock that is very rich in sulphite-containing material, (especially pyrite) came in contact with oxygen and water, resulting in the oxidisation of the pyrite that causes water with a high concentration of heavy metals and sulphide, characterised by a very low ph.


Mining software – a massive leap forward

It is quite amazing how information technology has advanced to a point where the mining industry, among many other sectors, has greatly benefited from the development of numerous
diverse software systems. A product “People are starting to realise that software is becoming more critical with regards to biometrics, process diaries and smelting processes to name but a few,” said Malcolm Rabsan, Dariel Solutions MD. Dariel Solutions has built and designed the Weighbridge Goods Receiving and Despatch software to combat theft and fraud.“Due to the location of the mines and the usual dispatching methods of ore, there’s a lot of theft.The problem in the past was that a lot of companies got third party haulage trucks, so what would happen is, a driver would come in with no approved ID, drive a truck out, and then stop on the side of the road and off-load.


Come to Botswana

Botswana is one of the many countries in Africa that is fortunate to boast a diverse wealth of minerals. Mining and Technical Exhibitions believe that they can bring some good suppliers to Jwaneng, allowing Jwaneng to support the suppliers.

Diamonds have been the leading component of Botswana’s mineral sector since large-scale diamond production began. Most of Botswana’s diamond production was of gem quality, which resulted in the country’s position as the world’s leading producer of diamond by value.

Copper, gold, nickel, and soda ash production also have held traditionally significant, though smaller roles in the national economy.

The abundance of coal is predicted to accelerate economic growth over the next few years, and a massive railway network to link landlocked sites to the ports is being put into plan. Charles Siwawa, CEO of the Botswana Chamber of Mines, said the railway lines are of paramount importance as they will bring a new level of development.

He has also emphasised on how the improvement of roads and communications have had a positive effect on accessibility to the western parts of the country, as most of the mining activities of the past decades have been focused on the eastern side.
