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.

Relationship Between Remuneration, Employee Morale, Stress and the Subsequent Impact on Safety, Productivity and Profitability.
2006
Study of pay and bonus structures on South African coal mines across management, staff and operator grades, for human resources practitioners and mine managers reviewing incentive schemes.
What this report foundBuilds on an earlier productivity audit that identified fluctuating bonuses and incentives as an influence on output, safety and employee stress.
R1500,00
Builds on an earlier productivity audit that identified fluctuating bonuses and incentives as an influence on output, safety and employee stress. The work examines how salaries, production bonuses and safety bonuses are graded and distributed across employee categories, how workers perceive that distribution, and whether incentives in practice motivate production and safe working. Stress and morale are treated as measures of wellbeing.
Treatment of Sulphate Rich Effluents with the Combined Electrolytic/Biological Process
2003
Laboratory work on producing hydrogen by electrolysis as the energy source for sulphate reducing bacteria, aimed at cutting the running cost of treating sulphate rich mine water.
What this report foundHydrogen for biological sulphate removal can be generated on site by electrolysis more cheaply than it can be bought.
R1500,00
Hydrogen for biological sulphate removal can be generated on site by electrolysis more cheaply than it can be bought. Stainless steel electrodes in acid mine drainage gave hydrogen at about a third of the bought in price while oxidising ferrous iron to ferric, which helps downstream treatment. Iron and zinc electrodes dissolved too quickly to be viable.
More Effective Use of Disposable Dust masks
Underground field trials, laboratory seal tests and operator questionnaires at two collieries, covering mask selection, fit, issue records and service time. For ventilation and occupational hygiene staff.

Dust masks worn by load haul dump operators passed 200 mg of filter loading in an average of 1.7 hours, and continuous miner, shuttle car and roofbolt operators reached the same point within two to five hours. Every mask failed laboratory fit testing. An eight hour service life is too long.
