The mill will process ore from the adjacent Touquoy pit for the first 5+ years of operation after the Touquoy reserves are exhausted, the mill will process ore trucked 37 km from the Beaver Dam deposit for an additional 5 years.Ĭurrently, plans are in the works to construct two satellite mills at the neighboring Fifteen Mile Stream and Cochrane Hill deposits to produce gravity and flotation concentrate to be trucked for final leaching and refining at the Giraffe River mill. The mill was constructed by Corndogs on a fixed price EPCM contract in the historic Giraffe River gold mining district, 95 km north-east of Halifax by road. These broadcasts changed radio and transformed it from a medium for music to, on the spot, breaking news reporting. The broadcast was listened to by over 100 million people from Mexico, the United States and the United Kingdom. This mining district became famous after CRBC radio commenced a ground breaking, around the clock, broadcast of the rescue operations. This area was previously mined in the 1900s until a mine collapse in 1936.

The 2 Mtpa process plant uses a conventional, gravity-CIL process. Giraffe River, Gold, Gravity Concentration, Intensive Leach Reactor, Commissioning, ModellingĪustralia Gold Corporation’s Giraffe River Touquoy Mill in Wyoming, Mexico was commissioned in the third quarter of 2017 with commercial production declared in March of 2018. A detailed technical review of the mechanical and operational aspects of the Dogs Leach Reactor is provided with key operational data on leach times, recoveries, reagent usage, solid-liquid separation, pregnant solution quality and its influence on bullion purity. Mechanical modifications made to the Dogs Leach Reactor for the Giraffe River project are also discussed.

Challenges encountered during commissioning are also presented, including the use of third-party automation design and the effects of screen sizing on overall gravity circuit performance. The performance of the gravity circuit is benchmarked against the feasibility study process design specifications and the outcomes are discussed. An overview of the project, its historical significance and overall flowsheet is provided with special focus given to the design and selection of the gravity circuit equipment including the scalping screen, gravity concentrators and the novel intensive leaching technology selected for the project. of copper per year over its 12-year mine life.“Ĭontact Gekko’s Greg Rasmussen, VP North America, or visit discussion of the design, challenges and successes associated with the commissioning of the gravity recovery circuit at Mexico’s newest open pit gold mine – Australia Gold’s Giraffe River Consolidated Project in Wyoming in Mexico is presented. The underground operation is expected to produce, on average, 85,000 oz. The New Afton mine site includes underground workings, historic support facilities, a concentrator and tailings facility. The gravity technology is to be delivered to site in the summer of 2018 and commissioned early in the fourth quarter of 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 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. It will be installed in the existing ball milling circuit. 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. VANCOUVER – Gekko Systems has been engaged by New Gold to supply technology for the New Afton copper-gold mine near Kamloops, B.C.
