about the S&P HRC
The Skelton & Plummer High Rate Clarifier, also known as S&P HRC, offers a complete turnkey dirty water clarification solution that can be utilised both on the surface or underground. The clarifier was developed for dirty water treatment in gold, platinum and other base metal mines – with the objective of achieving a throughput rate four to six times higher than conventional conical settlers. The requirement for a higher throughput rate became apparent in the mining industry in the eighties, when many settlers, because of increased production, were becoming hydraulically overloaded. It was often the case that the existing infrastructure could not be extended (by blasting new and/or bigger excavations) to accommodate additional water facilities.
The HRC’s popularity is largely due to its throughput rate, of up to six litres per m2 per second, under peak flow conditions.

how it works
Recycling dirty water for industrial & mining clients
Stefanutti Stocks’ complete dirty water clarification solution consists of four pieces of equipment – the degrit plant, the high rate clarifier (S&P HRC), the automatic gravity sand filter, and the plate and chamber filter press.
case study
Gold One New Kleinfontein Gold Mine
Specifications: Two S&P HRC (one 6,0 metre diameter, and one 7,5 metre diameter) internals, top support steelwork, clearwater overflow launders to clearwater dams and flocculent dosing plant.
A degrit plant complete with two 2155mm duty screens, a stilling box, dirty water launders to High Rate Clarifiers and conveyor for grit discharge.
Description: Two S&P HRCs were installed at the Gold One New Kleinfontein Gold Mine. As New Kleinfontein is in development the water-flow rates will change during the life of the mine, therefore two clarifiers were designed. The 6-metre diameter HRC will handle the initial dirty water, with the second 7.5-metre diameter HRC handling additional mine water requirements.
