VANCOUVER, Gekko Systems has been engaged by Canadian mining producer, New Gold Inc. (NGD), to supply technology for its New Afton copper-gold mine.

New Afton’s new gravity circuit addition will consist of Gekko's largest InLine 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.

Gekko’s new IPJ3500 is 4.5m high, 3.5m wide and has a feed capacity of 250 t/h.

The innovative flowsheet is utilising Gekko’s InLine 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.

 

”We look forward to working with Gekko Systems on this project to recover native copper from our grinding circuit” said Jennifer Katchen, Projects Metallurgist, New Afton Mine.

Located near Kamloops, British Columbia in Canada, 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 ounces of gold and 75 million pounds of copper per year over its 12-year mine life.

“Gekko is experiencing a high level of interest and demand in pre-concentration flowsheets which support footprint and energy reduction in process plants. New Gold have recognised the IPJ capacity to recover native copper in the New Afton flowsheet. We are excited to support this installation.” said Gekko System’s Greg Rasmussen, VP North America.
