More than 90 percent of the world's gold has been produced following the rushes of the mid to late 1800s [source: World Gold Council ]. The entire process of gold mining can be broken down roughly into four steps: prospecting, mining, extracting and refining. Early discoveries of gold relied on the blind luck of someone spotting a yellow glint ...

1. Locate Potential Deposits. One of the first steps of mineral exploration is to locate areas that are likely to yield mineral deposits. Since mineral deposits tend to form in clusters, prospective areas may be near other areas of known mineralization or near existing mine sites. They may also be identified with aeromagnetic surveys, satellite ...

SteepSlope Mining. At the end of 1999, only openpit mining was employed in the Zijinshan gold mine after several technical modifications. Through theoretical exploration and engineering practice, steepslope (α = 75°, β = 31°38°) mining was adopted (as shown in Fig. 2a).In addition, the number of bench groups and width of the working platforms were 46 and 3560 m, respectively.
