Identify Remnant Coal Deposits for Potential Exploitation by Small Business Developments
Screening of near surface remnant coal for small scale miners in Mpumalanga, with a map of candidate areas and of ground already worked out.
by Deborah S Xaba & Lesley S Jeffrey | March 2002
Shallow coal suitable for small scale opencast working was mapped in the northern Witbank and Highveld coalfields, using a limit of 30 m from surface to the top of the first seam. Most outcrop areas examined proved already mined out, and depth to the top seam increases southwards, though some ground remains available. Obtaining resource data was the main obstacle.

Market prices are set out for sodium sulphate, sodium chloride, sodium nitrate, potassium nitrate and potassium chloride, in South Africa and abroad, as at early 2011, with Chinese supplier quotes alongside United States averages. The work was done to test whether salts recovered from mine water brine could be sold at a worthwhile price.
