PrepQuip was awarded the contract to conduct the turn-key project of installing 1 off 1,8 m Ø, 1 off 2,2 m Ø and 1 off 3,2 m Ø flotation columns on a combined Merensky and UG2 PGM processing plant. PrepQuip also conducted an entire material balance over the entire circuit which predicted the performance of the flotation column circuit and the effect on the overall project fairly accurately.

Merensky and UG2 circuit integrated turnkey Column Flotation Project. The location is at a PGM Concentrator at the upper end of the Western Limb Bushveld Complex. The design input and placement of the units was a collaborative effort with the Operations Metallurgical Team with the premise to treat a combined Merensky/UG2 stream through a Merensky float circuit to effectively reduce Chrome percentage and increase overall plant recoveries on Final PGM Concentrate produced.

The purpose of the truck is to screen out any oversized material present in the firewater stream which in turn prevents nozzle blockages and equipment damage. The capacity of the truck with 4 x 300 NB In-line Guard Screens is 40 000 l/min. The equipment is unique in the way that no flow restriction is experienced during operation and automatic flushing of the unwanted material occurs during operation.
