  • Calcined Tincal Production Method by Calcination Autogenic Grinding and Separation (CASG) Method in a Single Step
    Publication number: 20110027158
    Abstract: This invention relates to production of micronized calcined tincal having a high content as a result of a succession of procedures consisting of: hardening of earth minerals due to lose of water during subjecting coarse tincal ore (Na2B4O7-10H2O) to heat treatment in rotary furnace with flights; forming of swollen soft, expanded structure of tincal ore caused by calcination and consequently being calcined followed by purification from impurities in a high rate in a way subjecting calcined tincal to pneumatic separation procedure by means of hot air used for calcination process after autogenic grinding effect of dried and hardened clays on swollen ore and obtaining micronized calcined tincal with high efficiency. The invention also relates to the production of compacted calcined tincal product with increased density in the second step as result of compacting micronized calcined tincal with low density under pressure.
