OVERVIEW

Mowana is located close to Botswana's second largest city, Francistown, in the north-eastern part of the country, in an area which has been mined for the past 400 years.

The process plant at Mowana is standard flotation process technology and has been designed to produce saleable copper concentrates from the treatment of 1MTPA of oxide, supergene and sulphide ores.

The process plant has two flotation circuits. Sulphide minerals are separated first, and tailings from the sulphide roughers are sent to an oxide circuit. Most other mineral species are recovered in the oxide flotation process. Concentrates are filtered to recover excess process water, as are tailings. Tailings will be dry stacked. Water recovered in the dewatering stages will be recycled to the various parts of the plant as process water.

SENET was responsible for the design, supply, and construction and commissioning of the process.

The implementation phase was preceded by a definitive cost estimate phase led by SENET, during which detailed cost estimates were developed for the capital and operating cost components associated with this project.
