The 4 Main Steps Of The Surface Mining Process | MSHA,
1.1 PHASES OF A MINING PROJECT There are different phases of a mining project, beginning with mineral ore exploration and ending with the post-closure period. What follows are the typical phases of a proposed mining project. Each phase of mining is associated with different sets of environmental impacts. 1.1.1 Exploration
6 Stages of the Mining Process | BOSS Magazine
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

02/11/2011· Mineral Extraction • Surface Mining: overburden (soil and rock on top of ore) is removed and becomes spoil. • 1. open pit mining – digging holes • 2. Dredging – scraping up underwater mineral deposits • 3. Area Strip Mining – on a flat area an earthmover strips overburden • 4. Contour Strip Mining – scraping ore from hilly areas 15.
a Surface Mine Stripping Costs in the Production Phase of
In surface mining operations, entities may find it necessary to remove mine waste materials (‘overburden’) to gain access to mineral ore deposits. This waste removal activity is known as ‘stripping’. During the development phase of the mine (before production begins), stripping costs are usually capitalised as part of the depreciable,
