The effect of recycle water quality on the flotation of a Platreef ore by Peku, Zandile

“…Mining operations consume a lot of water for many activities including mineral processing, slurry transport, dust suppression and employee requirements. Apart from mining (3%), there are other competing demands for water from other sectors, for example, the municipal (6.1%), agricultural (62%), energy (2%), forestry (3%), industrial sectors (3%), and domestic (27%) (Askham & Van der Poll, 2017). …”
