Abstract

The kinetics of batch grinding and heat treated of ulexite using different size fractions (-3350+2360, -2360+1700, -1700+1180, 1180+850, -850+600, -600+425, -425+300, -300+212 and -212+150 micrometers was determined using a standard Bond ball mill. It was found that breakage of ulexite follows the first order behavior for all feed sizes with the correlation coefficients equal to approximately 98%. The dry grinding of the single-sized fraction and heat treatment of ulexite showed that heat treatment samples were ground much faster than the original ulexite samples.
