Optimal coal processing route for the J 0.5 mm size fraction?

3 mm, the coal in the desliming screen underflow reports to the fines stream. This coal is usually further deslimed with hydrocyclones to yield a nominal plus 100-micron size fraction, which is sent to the fine coal beneficiation circuit. In South Africa, spirals are still the fine coal processing method of choice.
