  • Opencast Mining - an overview | ScienceDirect Topics

    The open-pit or open cast mining method is the obvious choice for a property with wide area of mineralization exposed or exists close to the surface and continues to greater depth. The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks. It is the most economic option for a deposit up to that depth where the economic ratio of ore and waste can

  • 9 Step Process for Discovering, Mining & Refining Gold

    2012-01-23· The result is 99.5% pure gold, which is then cast into electrodes (known as anodes) where it is then placed into an electrolytic cell. A current is then passed through the cell, with the end product being 99.99% pure gold. Step #9 – Mine reclamation. After a few years, gold reserves in the mine will be exhausted. In the old days, the mine would be boarded up and abandoned. Today

  • Returning Mined Land to Productivity Through Reclamation

    For example, since the passage of the 1977 Surface Mining Control and Reclamation Act (SMCRA) in the U.S., direct fees have been collected by government agencies from existing coal mining companies. Various states and Native American tribes have used over US$4.06 billion of those funds to reclaim almost "240,000 acres of hazardous high-priority coal-related problems". As described by the

  • Open-Pit Mining Methods

    Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit

  • Basics of an open pit mine - Mine Engineer.Com

    Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal. In a hard rock mine, the bottom of the pit would be the

    Byproduct mining is related to hard rock mining in that open pit or underground mining tunnels are used. In byproduct mining, gold is a secondary find. The main purpose of the mining operation is the recovery of Copper, sand, gravel or other products but significant quantities of Gold exist to make byproduct mining a profitable venture. An example of this kind of mining would be the Grasberg
