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.

Dense medium cyclones on the fine coal fraction lifted product yield well above the spiral circuit they were compared against and gave closer control of product quality. Cut point density control proved the hardest part of running the plant, medium properties being critical. Magnetic separator capacity had to match the duty, and a basement was needed to contain and recover medium spillage.
BCI Chemical Research & Analysis – Eutectic Freeze Crystallisation
2012
Desktop market and technology review of brine from coal related waste, covering global and South African demand, plant energy use and laboratory crystalliser results, for water treatment planners.
What this report foundEutectic freeze crystallisation was compared with evaporative crystallisation as a route for treating hypersaline mine brine.

Eutectic freeze crystallisation was compared with evaporative crystallisation as a route for treating hypersaline mine brine. Optimised commercial evaporative crystallisers use 40 to 50 kWh per cubic metre of feed. Laboratory work measured a eutectic temperature of -21.1 degrees Celsius for pure sodium chloride solution, and found that a large difference between coolant and solution caused scaling on the heat exchanger wall.
