Ecological integrity of a Mpumalanga wetland affected by coal mining was assessed before and after rehabilitation, using water quality, bacterial consortium, freshwater algae and vegetation indicators. The work sits within a wider programme to give the coal sector and regulators practical ways of limiting and mitigating mining impacts on wetlands.
Recharge in Rehabilitated Opencast Collieries
2019
Groundwater levels and pumping records from five rehabilitated opencast pits at South African collieries, for hydrogeologists and closure planners estimating post-mining water balances.
What this report foundRecharge factors of 23.5 per cent and 12.9 per cent were calculated at the two rehabilitated pits with complete data.
R1500,00
Recharge factors of 23.5 per cent and 12.9 per cent were calculated at the two rehabilitated pits with complete data. The higher value reflected surface drainage towards the pit centre and eroded topsoil; the lower one, a deep pit floor with well compacted spoil and intact cover. The rates are site specific and no generic formula could be derived.
BCI Chemical Research & Analysis – Potassium & Sodium
2011
Chemical market survey commissioned to price the by products of brine treatment, covering South African and global price levels for five salts and the sector outlook at the time.

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.
