the industrial process of open pit mining

  • What is Strip Mining? (with pictures)

    Jul 12, 2019Classically, strip mining is used to mine tar sand and coal. This technique is also referred to as open cast, open cut, or stripping. In this technique, the first step is the removal of trees, shrubs, and structures on the area to be mined, a process which is usually accomplished with heavy duty bulldozers.

    Open pit mining results in two waste streams: waste rock which contains no economic quantity of minerals but which must be removed to gain access to the orebody, and tailings which are the result of a mineral separation process in the concentrator or processing plant. The mining rate includes the mining of both waste and ore.
