In the case of artisanal mining, the extraction process usually takes a longer time as it involves low tech equipment and manual labor. Compared to alluvial mining, the postprocessing is shorter and is a less resourceconsuming task as diamonds are identified in situ of the work area. Offshore Marine Diamond Mining

Openpit Mining Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from .

The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock. Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface. Openpit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Apr 29, 2014· 10. Improving the efficiency of manufacturing processes. By targeting the goal of closely monitoring the standard mining supply chain, mining industry giants will be forced to confront the ways in which a company can improve its efficiency by seeing exactly where the organization is lacking in terms of sustainability and green mining initiatives.

Mar 14, 2014· The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the surface.

A single blast can break approx. 3,000 tonnes of ore. Once the ore is broken, excavators load the ore into haul trucks and transport it to a primary ore crusher where the diamond extracting process begins. The Kimberley Big Hole is an example of openpit mining. In underground mining, miners tunnel through Earth''s crust to the kimberlite pipe ...

Surface mining. Surface mining is used when deposits of the mineral or ore are found near the surface, where the overburden (gravel and sand) is relatively thin. It is a broad category as it includes different types of mining methods such as strip mining, openpit mining, mountaintop removal and dredging.

Openpit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, openpit produces harmful pollutants depending on the type of mineral being mined, and the type of mining process .
