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 process includes an open pit, from which the non chromite bearing surface materials and chromite ores are generally extracted. Rocks containing chromite ore are blasted, drilled, removed and loaded into large trucks for carrying to the crusher and other ore processing facilities. Underground mining is typically carried out to extract rocks ...
May 25, 2019· The cross section discussed previously will be subjected to optimization analysis for example. In all cases it will be assumed that the ramp at elevation 896 on the left wall will be necessary in the pit design. It is also assumed that mining of the ore body has not begun, so that the decision still has to be made as to the elevation of berms ...
resource. Both are linked to the optimization of profits, which in mineral operations is done by optimizing the ore cutoff grade, considering the block model geometry. The Coriorcco Gold Project refers to an open-pit mining operation at pre-feasibility stage located at about 4100 meters above sea level in the Peruvian Andes. This mining project is

The first study was for a mine planned below its existing open pit operation. SRK guided a fresh exploration program to generate data for the study. Following the study, detailed engineering will be initiated. Simultaneously, SRK initiated another study for the client's other chromite leasehold located south of the existing open pit.
