BCI Chemical Research & Analysis – Calcium & Magnesium
Desk research on two mine water by products, closing out the economic analysis behind proposed brine treatment plants, for readers judging whether recovered salts can be sold.
Prices for calcium and magnesium sulphate are recorded for South Africa and for world markets as at mid 2012, together with price trends and the groundwater chemistry that governs which salts a mine water stream will yield. The figures were assembled to support feasibility studies on a eutectic freeze crystallisation plant and an ion exchange plant.
