:: Chrome Tailings-Treatment Plant for Aquarius

Bateman Africa (Pty) Ltd's small-projects team (previously known as Tawana (Pty) Ltd) has completed the first phase of a project for the establishment of the RKI chrome tailings-treatment plant for Aquarius Platinum (Africa) Corporate Services (Pty) Ltd in Kroondal, near Rustenburg, RSA. This phase involved the design, upfront engineering and determination of the capital costs.

Feed to the RKI chrome tailings-treatment plant will be old dumps and current tailings streams derived from the beneficiation processes employed by neighbouring chromite mines in the Kroondal area. In addition to generating profitable income, the clean-up of old dumps on the Kroondal property, established during early chromite-mining activities, further enhances Aquarius's commitment to sound environmental practice.

The cost-effectiveness of the treatment plant is increased by the fact that the layout of the plant makes use of the slope of the land on which the plant is to be built. This makes it possible for the tank cell pairs to be terraced, thereby reducing the height that would normally be required by a conventional plant. The complete plant will therefore be built with a difference in elevation of only 1.5 m.

The plant will be equipped with conventional tank-type flotation cells and will have a capacity that will be capable of processing newly-generated tailings from neighbouring chrome mines, as well as the reclaimed material from the mines' existing dumps. The plant has, however, been designed along modular lines to facilitate expansion in the future.
