Treatment of acid mine drainage for reuse in irrigation
Mintek | October 2022
R1500,00
Description
Mintek’s cloSURETM technology has been specifically developed for mine sites post-closure and would be suitable for implementation at sites with low or unpredictable flow, at remote locations and in areas lacking services/infrastructure. The two- stage process, consisting of a bioreduction followed by a bio-oxidation step, is intended to produce water that is fit for re-use, specifically in irrigated agriculture. The objective is to reduce the cost of mine water treatment, and to create the opportunity for revenue generation through the re-use of the water to produce crops, and possibly through the production of a bio-sulphur product.

Heat exchanger material governs how fast ice scale forms during eutectic freeze crystallisation of dilute brine. Induction time fell as thermal conductivity rose, so copper scaled first, while aluminium gave the lowest scaling rate because its low surface energy pushed ice crystallisation into the bulk. Stainless steel delayed onset but scaled heavily once nucleation started.

A rating and ranking system was applied to South African coalfields and, separately, to the coal bearing countries elsewhere in the Southern African Development Community. The Waterberg ranked highest in South Africa and is the coalfield most worth detailed investigation as Witbank output declines. Botswana ranked highest among the other member states on contained resources and exploitation potential.

R1500,00
Dust masks worn by load haul dump operators passed 200 mg of filter loading in an average of 1.7 hours, and continuous miner, shuttle car and roofbolt operators reached the same point within two to five hours. Every mask failed laboratory fit testing. An eight hour service life is too long.
