BCI Chemical Research & Analysis – Calcium & Magnesium

Jacques Magliolo

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.

What this report found

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.

What this report found

Ion exchange converted reverse osmosis brine from a power station treating colliery water and cooling tower blowdown into fertiliser and explosives salts, with no liquid effluent left to dispose of. Part of the water rejected by the reverse osmosis stage was also recovered as potable water. Brine is currently used for dust suppression and stored underground.

What this report found

Co-treating coal discards with sewage sludge by hydrothermal carbonisation gave hydrochars with better physicochemical properties than treating either waste alone. The blended hydrochar reached a surface area of 20.35 m2/g and a pore volume of 0.38 cm3/g, and removed 97.19% of nevirapine and 93.32% of lamivudine from recycled water. Routes to activated carbon and hydrogen storage were also assessed.

Rehabilitation of Mined Land – Soil Compaction Alleviation

2011

Final report on mined land rehabilitation trials comparing pasture species and organic amendments on compacted mine soil against normal agricultural soil, for rehabilitation and pasture planning.

What this report foundExperimental studies tested ways to alleviate compaction on mine soils by combining mechanical treatment with organic material.

What this report found

Experimental studies tested ways to alleviate compaction on mine soils by combining mechanical treatment with organic material. Survival of 16 pasture species was recorded on mechanically ameliorated compacted soil, dry matter and leaf area were measured for tall fescue and cocksfoot at different levels of organic material, and soil fertility, bulk density and root biomass were tracked under irrigated and dryland grass.
