• How Ore Sorting Leads to Mineral Processing Success

    The ore and waste rocks need to be liberated from one another so that the sensors can properly identify each particle for sorting. In general, ore sorters can process particles ranging from 30-120mm in size. As a general rule, the largest particle should be no more than three times the size of the smallest particle for sorting.

  • Potash Ore Grades – Check the Units

     · Therefore when comparing potash resource grades between deposits, one must be vigilant for the units used since there is a significant difference. The conversion from K2O to KCl is based on the formula K2O = 0.6317 x KCl. So a grade of 25% K20 is equal to 25/0.6317 = 39.6% KCl. The KCl grade value is significantly higher.
