Currently, Indonesia produces around four percent of global gold production, half of which originates from the giant Grasberg mine, the world largest gold mine, on the western half of Papua. This mine, which is believed to contain the world's largest gold reserves (67.4 million ounces), is majority-owned by the ...
Highwall mining is also safer than other types of mining, and when, it occurs at the surface, it often produces the same amount of output as mining underground does. Smaller blocks of coal can be accessed with high wall mining, and operations can take place around structures or geological impediments that may otherwise impinge upon the ...

Sustainable Development and Mining. Mining impacts always existed and we still have mines opened in Roman times with acid mine drainage, waste piles, and environmental contamination. Large-scale mining grew during the 19th and 20th centuries with impacts neglected and hidden costs.
Minor types of gold deposits are not discussed in this paper. As proposed by Robert et al. (1997) and Poulsen et al. (2000), many of these gold deposit types can be grouped into clans, i.e. families of deposits that either formed by related processes or that are distinct products of …
