Major Mines Projects | Donkin Mine

Sterilized resources are those that are unavailable for mining due to environmental or other restrictions. At Donkin, coal within 75 m of an offshore drill hole that intersects the coal seam in question is unable to be mined. For a 2m thick seam, this equates to approximately 50,000 tonnes of coal.

A Comparison of Coal Beneficiation Methods

Gravity Separation. To effect the gravity separation of coal and mineral matter, 500 g crushed coal (6 mm χ 0) were added to 2000 ml tetrachloroethylene (specific gravity = ) in a large beaker placed in a well ventilated hood. The mixture was stirred by hand to insure wetting of all particles, an d then it was allow ed to stand for 30 min.

Gravity Separation | Hazen Research

Gravity Separation. If a mineral exists in an ore as discrete particles separable from the worthless rock (gangue), it is possible to physically concentrate the valuable mineral and discard the gangue. Gravity separation, relies on the difference in density of the mineral and the gangue. This technology can be applied to primary recovery,...

However, column flotation is not efficient for treating fine coal containing significant amounts of mixedphase particles. Fortunately, enhanced gravity separation has proved to have the ability to treat the mixedphased particles more effectively. A disadvantage of gravity separation is that ultrafine clay particles are not easily rejected.

CLEAN COAL TECHNOLOGY (CCT) – I

through a process called gravity separation. One technique involves feeding the coal into barrels containing a fluid that has a density which causes the coal to float, while unwanted material sinks and is removed from the fuel mix. The coal is then pulverised and prepared for burning.
