Cost of Production
The first step when calculating the cost involved in making a product is to determine the fixed costs. The next step is to determine the variable costs incurred in the production process. Then, add the fixed costs and variable costs, and divide the total cost by the number of items produced to get the average cost per unit.

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.
