The mine has a chromite resource of 32Mt comprising of four seams, namely the LG6, MG1, MG2 and MG4. All four seams outcrop on the property. It has a New Order Mining Right and BEE partners own 19% of the operation. The mine commenced operations in July 2008. The open cast mining is outsourced to a contractor.
After extracting the chromite ore by surface mining up to the economic pit bottom, the remaining reserves were being mined by underground method. In the Sukinda valley chromite deposits, both the wall rocks and ore body are weak, highly weathered. These mines were operated by opencast method.

Negative impacts of opencast mining on the environment . Jul 07, 2015A major part of iron ore, nonferrous metals, brown coal, building materials and minerals for industry is being excavated in opencast mines. This type of mining has a deep impact on the natural strata. Opencast mining changes geological, hydrological and geotechnical conditions.
Nov 13, 2017 The chromite mining effluent in Odisha typically has a hexavalent chromium concentration of 2 to 5 mg/L, as against a safe limit of 0.05 mg/L for human consumption. If hexavalent chromium laden effluent is released untreated, it can severely contaminate the nearby water bodies and pose a threat to the biotic community in the vicinity.

Platinum (element 78, symbol Pt) is a dense, silvery-gray metal. The platinum group of elements consists of metals with similar physical properties as platinum and these elements are among the rarest in the Earths crust. They have high melting points, are dense or heavy and are non-reactive with other elements.
Opencast chromite mining generate huge volumes of seepage water. Eventhough chromium in chromite is in the trivalent state, some hexavalent Cr(VI) is always formed due to certain complex reactions. If Cr(VI) containing ... dumps, steps should be taken to stabilize the lower slopes of the unused faces.
Opencast Mining for chromium in Sukinda valley commenced since 1950. Total 17 mining leases have been granted for chromite ore mining in Jajpur and Dhenkanal underground) and 5 are not in operation due to want of statutory clearances (www.orissaminerals.gov.in). The list of given in Table 1.
chromite reserve and it is exploited mostly by opencast mining process since 1950. Hexavalent chromium is a highly toxic form of chromium metal mainly used in different industrial applications for its anticorrosive properties.Due to open cast mining process lots of over burden
mining containing 42% Cr203, and the Cr/Fe ratio range is between 1,30 -1,38. 3. Mining of Chromite The mining techniques used depend on the ore body. Typically in South Africa, there are opencast, conventional scraper-winch mining (figure 4) and trackless mechanised mining with Load Haul Dumpers (LHDs) (figure 5).
bord and pillar. Only isolated opencast mining is available to most producers now, as many of the outcrops have been mined already. For any resource and chromite ore supply, mining generates material in a range of particle sizes from large lumps to fine sand. Mining of the LG6 and MG1/2 seams produces typically between 540% lumpy material that
