Surface mining is a process whereby soil and rock overlying the mineral deposit are removed. There are two principle types of surface mining, strip mining and open-pit mining (see Fig. 8.8).Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock
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 post-processing is shorter and is a less resource-consuming task as diamonds are identified in situ of the work area

Strip Mining involves stripping the surface away from the mineral that’s being excavated (usually coal). Soil, rock, and vegetation over the mineral seam is removed with huge machines, including bucket-wheel excavators. Open-Pit Mining is a technique of extracting rock or minerals from the earth by their removal from an open-air pit
Aug 01, 2019 Open-pit mining. This method can be used if the ore is close to the surface and it is known to be the most economical mineral extraction method. In this type of mining, overburdens are removed to extract the desired metals using trucks or other conveying machines (Zhao et al., 2013). 2.2. Underground mining
Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2019 amounted to 53,656 tonnes. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production. Other countries producing more than 1,000 tonnes per year included Namibia
Mining platinum in placer deposits is a relatively simple process. Dredges scoop the platinum-bearing sand or gravel from riverbeds or mining pits. The material is washed until platinum grains or nuggets are captured and pulled from the surrounding material. Sperrylite, or platinum arsenide. Photo from Thomas A. Loomis, Dakota Matrix Minerals
