Van Dykespruit 2
AST’s pilot plant at VanDykspruit – the first complete plant of its kind in South Africa. The modular design of this washing system ensures highly accurate separation of silts and clays from mined material. This results in the production of high quality sand products that command the highest possible commercial value.
There is an increased shortage of water. AST’s technology offers operators a proven way to increase the efficiency of sand washing operations while at the same time maintaining the highest levels of product quality.
The waste-water treatment process, reduces the volume of fresh water to feed the washing plant by over 90%, a step that meant the plant requires only 22m³ of fresh water/hour. Without the addition of the AquaCycle thickener the figure would be 220m³/hour – a HUGE reduction in water usage, being controlled, and confined to a much smaller plant and mining operation “footprint.”
