Not only does the mining equipment employed in the operation impact the overall mine productivity, ventilation requirements, and maintenance considerations of the entire mining operation, but also the overall project economics.

    A small gold mine flowsheet is shown below together with cost data which clearly shows the results that can be ‘obtained when handling a low grade ore by a simple process. There are many commendable features in such a set up and no complicated machines or practs are embodied in this plan. In fact, its simplicity is appealing and the results obtained prove the practicability of this

    effective for small-scale operations. Most bauxite, iron, and copper ore is mined by open pit techniques, lead and zinc ore are principally extracted by underground mining methods, and precious metals, particularly gold and most notably in the USA and Australia, tend to be recovered in recent years from low-grade deposits by surface mining.

  • Equipment Selection for Surface Mining: A Review

    A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.

    The primary operations required in underground are rock breakage an d material handling. If the target is sufficiently soft (e.g., coal and rock salt), mechanical excavation utilizing continuous miners, shearers, ploughs/plows, and so on, can be employed. In contrast, drilling and blasting are usually employed when the ore is too hard for cutting.
