Based on years of experience in the mining industry in South Africa, Krohne has been able to offer the Optiflux 4000 electromagnetic flow sensor as the proven choice when selecting a flow meter. It has been used over the years by mines in South Africa and the rest of Africa where a reliable and accurate flow meter is required to perform under harsh conditions.
There's another form of alluvial mining called artisanal mining. In essence, it is basically the same method employed by gold diggers which involves the screening and straining of mud. In the case of artisanal mining, the extraction process usually takes a longer time .
Leaching and adsorption. To achieve this, carbon is fed through the tanks (4) and the gold and silver adsorbs (attaches) to the carbon granules. Carbon is heated to 600 degrees C and fed into the circuit in the opposite direction to the slurry flow, moving from the last adsorption tank to the first.
Mining. First, a large vertical hole is excavated, typically 1,750 feet (533 m) in diameter. Levels are placed approximately every 40 feet (12 m). Along these levels are horizontal tunnels known as scraper drifts. In the drifts, there are small inclined coneshaped openings at intervals of every 11 feet (3 m) or so.

Hydraulic mining of tailings. During the mining operation the screened material was pumped to a header tank almost 5 km away at a height elevation of 200 m. From the header tank the tailings were gravitational fed to a new tailings impoundment 50 km away. See .
Most of the PGM mines in South Africa operate at a depth below 500 metres and up to 2 kilometres. Their orebodies are tabular and narrow, varying in width between metres and metres and requiring labourintensive mining techniques.
The flow of the Nayshkatooyaow River will be decreased by at least 15%. A kilometer stretch of South Granny Creek will be "moved.". million m3 of muskeg, including trees and other plants, will be removed. River crossings may lead to siltation of rivers and creeks and impact water quality.
Discovery of the Gold in 1884. At the time mineral outputs averaged £1 per oz per ton of rock mined. Despite this, the vast majority of the Reef's companies were still engaged in surface mining and the only real shafts sunk to date were on the Jubilee and Langlaagte properties.
