WOA1A method of grinding a mineral-containing

A method of grinding a mineral-containing ore which includes grinding the mineral-containing ore in a primary milling process and thereafter fine grinding the mineral-containing ore in a secondary ball-mill. A composite grinding medium comprising a mixture of steel balls and pebbles is used in the secondary ball-mill. The pebbles have an average size which is relatively smaller than the

Bond Work Index Formula-Equation911 Metallurgist

 · For any circuit whether a crushing circuit a rod mill or a closed ball mill circuit the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um. The sample was received crushed appropriately for the ball mill test.

 · Ball Mills are generally used to grind material 1/4 inch and finer down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers such as screens spiral

Hazard Identification Risk Assessment and Control

General. India has the fourth largest iron ore reserves in the world after Russia Brazil and Australia. As per the survey conducted by the Indian Bureau of Mines (IBM) in April 2000 India had 9919 million tonnes of recoverable reserves of haematite and 3546 million tonnes of magnetite. As good quality iron ore deposits are depleting very fast beneficiation technologies have to be

Wet grindability of an industrial ore and its breakage

 · Research Highlights Wet grindability of a diasporic ore was investigated in a laboratory ball mill. Three size-intervals fitted first-order breakage but the coarsest interval did not. The non-first order was most probably caused by the heterogeneity of the material. Breakage parameters were back-calculated and validation results are in good accuracy. Non-normalizable breakage distribution
