beneficiationTreatment of raw material (such as pulverized ore) to improve physical or chemical properties in preparation for further processing. Beneficiation techniques include washing, sizing of particulates, and concentration (which involves the separation of valuable minerals from the other raw materials received from a grinding mill). In large-scale operations, various distinguishing properties of the minerals to be separated (e.g., magnetism, wettability, density) are exploited to concentrate the desirable components. Beneficiation also is used in the ceramics and clay industries. See also flotation; mining; mineral processing. |

A density separation approach (Dense Media Separation) may be considered to beneficiate the xenolith, but significant inefficiencies will occur, although any free diamonds would be recovered with the xenolith rocks. Furthermore, the Federal Government still maintains the export withholding tax for oil, and the fiscal incentives announced by the Federal Government to beneficiate concessionaries on the exploration of new basins are not clear. However, our bench-scale tests results lead us to believe that our technology will be able to economically beneficiate and remediate coal on commercial scale, including that in the coal waste impoundment category. |
