The gold telluride ores occur with silver, or with silver, lead and antimony, or as native gold accompanied by other tellurides. These ores are often sent direct to the smelters for treatment. A fifth type is the disseminated ore type. They are often low in grade but large. They fill large fracture and fault zones or replace certain geologic horizons. They are the result of the circulation of

Witwatersrand Wikipedia

Gold is found in the conglomerate strata of the younger members which is relatively plentiful in the gold ores of the Witwatersrand, oxidises to insoluble ferric oxide (Fe 2 O 3) and sulfuric acid (H 2 SO 4). Thus, when mine waste comes into contact with oxygenated rainwater, sulfuric acid is released into the ground water. Acid mine drainage, as the phenomenon is called, has become a

viability of optical sorting of Witwatersrand type conglomerate ores. The first case study deals with recovering gold reef from surface rock dumps (SRD) at Kloof Gold Mine. Over a period from 2003 to 2010 various test work campaigns and pilot plant work was carried out proving both the technical and economic viability of optical sorting. Typically the grade of a SRD ranges between 0.5 g/t to 1

Witwatersrand Basin (RSA)

The gold mines in this area are situated around an ancient sea (over 2700 million years old) where rivers deposited their sediments in the form of sand and gravel which became the conglomerate containing the gold. The Witwatersrand Basin is approximatly 350 km long and 200 km wide. The gold mines in this area are possibly the deepest mines in the world (mining operations at 3600 m and

Visualizing the Formation of Uranium and Gold Ore

The highest concentration of uraninite and gold takes place in conglomerate units, also known as “reefs” (minable units). Seams of organic matter have a close spatial association with these reefs, indicating a key role in the ore-forming process. Within the Witwatersrand, the formation of uranium and gold ore has been an ongoing debate, with opinions often divided on whether the ores are

He classified the ore genetic theories into three types: (1) (Modified) Placer Model where the gold was of placer origin, being derived by erosion from pre-existing gold-bearing structures, and possibly being recrystallized after deposition in the conglomerate reefs; (2) Precipitation Model in which gold and pyrite
