    In this conventional mining refers to the ‘standard’ narrow tabular orebody mining method for which South Africa is famous. It is, and has been, widely practised throughout the industry in gold, Merensky reef, chrome reefs, and the UG2. The main advantage of conventional mining is that access to the orebody is in the footwall, so the

  • Opencast Mining an overview ScienceDirect Topics

    The open pit or open cast mining method is the obvious cho for a property with a wide area of mineralization exposed or existing close to the surface and continuing to greater depths. The open pit exposes the orebody from the surface by separate removal of ore and associated waste rocks.

    Sep 29, 2008· Cooperation between Concor Mining and Impala Platinum has facilitated the Impala Opencast project. Hans Baasden, general manager Impala Platinum says that Concor Mining was originally selected through an open tender process in 2002. “Impala Platinum is an underground mining company and does not have the necessary expertise or the resources to undertake an opencast mining

  • Platinum is produced in South Africa by Amplats, Impala

    Western Platinum was the first company to exploit the UG2 on a large scale for its PGM content 17. Metallurgical investigations were undertaken in conjunction with Mintek during 1980. Mining of the UG2 at Western Platinum Mine commenced in 1982, and the UG2 concentrator started up in March 1983.

  • Environmental Impact of Artisanal Gold Mining in Luku

    Artisanal and Small-Scale Mining is a means of livelihood adopted primarily in rural areas (Veiga, 2003). Minerals are extracted in Artisanal and Small-Scale Mining by people ing with simple tools and equipment (Bradshaw et al., 1997). This is sometimes called informal sector, which is outside the legal and regulatory frame (Azubike, 2011).

However, with rising costs, the scarcity of skilled or and the trend toward mechanization, the method has been largely displaced by sublevel stoping and cut-and-fill. Sublevel stoping will therefore be the only unsupported methods examined in detail here.

    Chromite mining wastes have the potential to cause serious environmental contamination. This occurs in places around the world where these wastes are inadequately managed. Overburden is an important type of mine waste. Overburden includes the soil and rock that is removed to gain access to ore deposits at open cast mines.
