SEPARATION: Gekko supplies native copper gravity circuit

Gekko’s in-line pressure jig IPJ3500.

VANCOUVER – Gekko Systems has been engaged by New Gold to supply technology for the New Afton copper-gold mine near Kamloops, B.C.

New Afton’s new gravity circuit addition will consist of Gekko’s largest in-line pressure jig (IPJ) unit – the IPJ3500 – as well as an IPJ2400 and its proven mag-screen technology. It will be installed in the existing ball milling circuit.

The innovative flowsheet is utilising Gekko’s in-line pressure jig for the pre-concentration of native copper in the supergene ore that will be an increasing portion of the incoming ore to the plant in 2018. The IPJs were selected for this application as they can be fed a relatively coarse particle size distribution, thus allowing the recovery of larger native copper flakes.

The gravity technology is to be delivered to site in the summer of 2018 and commissioned early in the fourth quarter of 2018.

The New Afton mine site includes underground workings, historic support facilities, a concentrator and tailings facility. The underground operation is expected to produce, on average, 85,000 oz. of gold and 75 million lb. of copper per year over its 12-year mine life.“
