Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface.
What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering.

Samancor has two mining centres: Eastern Chrome Mines (ECM) in the Steelport area of Mpumalanga Province and Western Chrome Mines (WCM) near Rustenberg and Brits in Northwest Province. Both units now comprise five underground mining areas, each with a hoisting shaft, while WCM also includes an open-cut mine.
Although the intention of chromite mining is to remove chromite from the ore for the production of ferrochrome, the process is not efficient, so mining and smelting wastes including dust, wastewater, tailings, waste rock, and slag (produced during ferrochrome separation from the ore) still can contain different forms of Cr, including Cr(VI).
Mining Waste. Mining waste is the high-volume material that originates from the processes of excavation, dressing and further physical and chemical processing of wide range of metalliferous and non-metalliferous minerals by opencast and deep shaft methods.
Chromite mining. PDF Chromite is a mineral that contains chromium.
