Illegal Limpopo chrome mining — digging deep for empty promises

Sep 23, 2016 Before Niemoller and the other "investors" came, people informally mined the ore dumps abandoned by the mining company when it lost its licence. They say Niemoller arrived in April, making promises of a better life. He brought in machinery but he never applied for a permit — neither did he fork out the

Samancor Chrome Mines Mining Technology

With low electricity prices, South Africa has been able to expand chromite and ferrochrome production more or less continuously since the AOD process was developed in the 1960s to use ferrochrome smelted from lowergrade ores. Samancor was created in 1975 and its Chrome Division grew, mainly by acquisition,

In Situ Bioremediation of Chromium (VI) In a Simulated Ferrochrome

Stability of chromium in the tailing dumps and stockpiles of chromium concentrate at chrome mining fields is affected by pH, redox potential, and the presence of other metallic species in the waste rocks. It is desirable to keep chromium in the dump site in the trivalent state since the hexavalent state, Cr(VI), is highly mobile 

Samancor Our Business Products

In trackless mechanised mining the seam, which is contaminated by an internal waste parting, is drilled and blasted by conventional means. The blasted rock consisting of some 70 percent chrome ore and 30 percent waste, is then loaded by loadhauldump units and transported to conveyor loading points from where it is

Converting Tailings Dumps into Mineral Resources Energy

This is particularly the case for tailings dumps created from the processing of platinum group elements (PGEs) from the UG2 reef in the Bushveld Complex (BC) of South Africa, which are now being retreated to recover chrome. Similarly, tailings dumps arising from the processing of chrome ore in the Lower Group reefs of 

Chromite Wikipedia

Chromite is an iron chromium oxide: FeCr2O4. It is an oxide mineral belonging to the spinel group. Magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr2O4) substitution of aluminium occurs leading to hercynite (FeAl2O4). It is by far the most industrially important
