Surface mining process somewhat varies depending on how the target mineral deposit is situated, e.g. horizontal, inclined, or interbedded, but commonly includes the following four steps: 1) top soil removal, 2) overburden removal, 3) extraction of ore, and 4) reclamation of mined-out site. Each step is further detailed in Table 1.
