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.
