Zululand Anthracite Colliery (ZAC) has commissioned a new 25 tph filter press at its coal washing plant in Emakhalathini, KwaZulu-Natal.

The filter press removes slurry from the water used in the coal washing process and will aid in preventing incidents such as the coal slurry spill which occurred at ZAC, after the end wall at Slurry Pond 3 failed on 24 December 2021.

As ZAC Engineering Production Superintendent, Howard Atkinson, explained: “The filter press filters slurry-laden water and removes all the ultra-fines from the water to enable reclaimed water to be reused in the beneficiation process.”

The filter press plant, which costs ZAR 14.5 million, was commissioned on 10 May 2022 and was in full production by 16 May 2022.

The conservation, protection and management of water is a top priority for ZAC.

“The principal aim of ZAC’s sustainable water management policy is to minimise and reduce freshwater consumption in all our operations,” stated ZAC General Manager, Wayne Rowe.
