CDC Mining Task Analysis NIOSH
Ideally, a task analysis should be used when designing the system. By performing a task analysis early on in the system design, the user''s capabilities and limitations can be incorporated into the design of the equipment, procedures, and training. However, it does not end here. Like the overall design process, task analysis is an iterative process.

Neutralization of Acid Mine Water and Sludge Disposal
Neutralization is generally the first step in treating acid mine water (gold, operational and abandoned coal mines). In Gauteng a volume of 240 Mℓ/d of acid mine water from gold mining requires treatment. At an acidity of 3 g/ℓ (as CaCO 3), a lime (CaO) price of R360 and a purity of 93 % the neutralization cost would amount to R57 million/a
