In addition to the major cyclone package currently being installed at First Quantum Minerals Ltd’s new Sentinel copper project in Northern Zambia,

Weir Minerals Africa has since been awarded two more packages — one for Sentinel and the other for Enterprise nickel, which are also part of the greater Trident project.

An Isogate WS knife gate valve, incorporating a Linatex rubber sleeve

The first order, placed in mid-2012, represented one of the biggest cyclone cluster installations of its kind ever supplied by

Weir Minerals Africa into an African application and included two 12x 650CVX cyclone clusters for the SAG mill application and four

16x 650CVX cyclone clusters for the ball mill classification duties. Commissioning of the equipment is scheduled for the second quarter of 2014.

The subsequent package for Sentinel comprises more than 50 Warman® AH horizontal centrifugal slurry and AHF horizontal froth pumps, ranging in size from small to large, and 55 Warman® vertical spindle pumps capable of handling large volumes.

This package also includes the supply of 611 Isogate® knife gate slurry valves ranging from 2” to 48” in size with manual, pneumatic and hydraulic actuation and a high pressure range of 24” high pressure Isogate® knife gate slurry valves that include Isogate WS, WB, WBP and WH units.  It is one of the biggest Isogate® knife gate valve orders that Weir Minerals Africa has received on the continent to date.

Two 12 x 650CVX Cavex clusters for the Sentinel SAG mill

The third package comprises all the cyclones needed on the Enterprise nickel project — one cluster of 10 Cavex® 500CVX hydrocyclones and two clusters of four Cavex® 500CVX hydrocyclones for installation at the Enterprise ball and SAG mills. As with the earlier

Sentinel package, all Weir Minerals Africa cyclone cluster

s are designed and manufactured in South Africa. The company will also supply 53 horizontal Warman® AH slurry pump

s and AHF froth pumps as part of this order.
