Chemistry of nickel and copper production from sulphide ores
Nickel is one of Zimbabwe's principle metallurgical exports. It is processed to a very high level of purity and hence has a high value. The economics of nickel production can be difficult, as the selling value of nickel varies tremendously with time, from a low of US$ 3 900 per ton in late 1998 to US$ 10 100 per ton in May 2000, and to US$ 8 500 less than a year later.
