Abstract

The effect of grinding in different pure mineral has been generally studied. However, very little work has been done in mixed skarn tungsten. This paper describes the breakage rates of the mixed skarn tungsten from milling kinetics at a laboratory ball mill. Firstly, the breakage rates of different particle sizes in constant operating conditions have been done in a ball mill having 13.5 cm diameter and 14.6 cm length, such as mill speed, slurry density and media size. Secondly, tests were conducted in the best suitable grinding condition to studied the grinding performance in the mixed skarn tungsten. Test results indicates that the specific rates of breakage (ki) value increasing as feed size fraction increased excluded -2+1mm fraction because the ball size is too small to break the coarser particles. The bigger ball loads 30, 40 mm size was significant for breaking the particles larger than 0.3 mm, smaller ball loads 20 mm size was at work on the particles smaller than 0.3 mm. It should be noted that the above operation condition have verified with further industrial.
