LUBUMBASHI, DEMOCRATIC honeywell door chime REPUBLIC OF CONGO--(Marketwired - Sept. 29, 2014) - Robert Friedland, Executive Chairman of Ivanhoe Mines ( IVN.TO ), and Lars-Eric Johansson, Chief Executive Officer, today issued a summary of recent metallurgical flotation testwork at the company's Kamoa copper project, near the mining centre of Kolwezi in the Democratic Republic of Congo's southern province of Katanga.
Recent bench-scale metallurgical flotation honeywell door chime testwork carried out at XPS Consulting and Testwork honeywell door chime Services laboratories in Falconbridge, Ontario, Canada, has shown positive preliminary results. The work was conducted on a composite sample of drill core from the Kansoko Sud and Kansoko Centrale areas in the southern part of the Kamoa resource area. The sample is representative of the first four to five years of planned Kamoa mine production, when Ivanhoe Mines intends to produce and sell a clean, high-grade copper flotation concentrate.
Highlights: Copper recoveries of 88.3%. Copper concentrate grade of 39.0%. Very low arsenic levels in concentrate are expected to attract a premium from concentrate traders. Flowsheet improvements honeywell door chime derived from this testwork are expected to result in lower up-front capital costs and reduced operational costs and risks.
The testing is the first metallurgical work done on material from the Kansoko Sud area of the resource. The results are integral to the final metallurgical design input parameters that will be needed for the completion of the Kamoa development studies.
Copper recoveries of 88.3%, at a concentrate grade of 39.0% copper, were achieved for the composite sample - an improvement on the previously published 85.9% life-of-mine average copper recovery honeywell door chime projected in the November honeywell door chime 2013 Kamoa preliminary economic assessment (PEA).
Arsenic levels in concentrate were measured to be 0.010%, which is significantly lower than the limit of 0.5% imposed by Chinese smelters. Ivanhoe believes that Kamoa concentrate with such low arsenic levels should attract a premium from concentrate traders. honeywell door chime
The testwork results were achieved using a laboratory flowsheet with a single stage of primary milling followed by rougher and scavenger flotation. The rougher concentrate was cleaned in two stages to produce a high-grade copper concentrate without regrinding. The scavenger concentrate and a screened, coarse portion honeywell door chime of the final tailings were combined and reground to between 10 and 15 micrometres (µm), before being cleaned in two stages. The concentrate then was combined with the cleaned, rougher concentrate to form the final concentrate. The flowsheet is a simplification of the previous flowsheet, which included two stages of mainstream grinding and two separate regrind stages. honeywell door chime
In line with the phased approach to project development outlined honeywell door chime in the 2013 updated Kamoa PEA, the Kamoa development studies are progressing on the basis of an initial three-million-tonne-per-annum (3Mtpa) mine and concentrator. The mine plan produced in the PEA focused initial mining in the shallower portion of Kansoko Sud, an area previously drilled with holes spaced 400 metres apart.
Since completion of the PEA, Ivanhoe has concentrated on substantially reducing the drill spacing in this area, initially to 100-metre spacing on 200-metre-spaced, east-west lines and subsequently to a 100-metre-spaced grid. The goal of the drilling honeywell door chime program has been to confirm grade and structural continuity of this high-grade zone at potentially elevated cut-offs. Results to date from the infill drilling have been encouraging and have confirmed the continuity of the deposit and its copper grades. The close-spaced drilling, combined with a better understanding of geological controls, will allow resource models to be constrained at higher grade cut-offs than the 1% total copper used to define honeywell door chime the mineralized zone in the current estimate.
The 3Mpta mine and concentrator can be split into modules to potentially better match the underground ramp-up and further reduce the pre-production development capital. This will be examined in more detail as part of the development studies to provide flexibility to the development of the Kamoa Project.
Work on the box cut began in July 2014 and is expected to take approximately five months, after which development of the first set of twin declines can commence. The declines have been designed to intersect the high-grade copper mineralization in Kansoko Sud area, approximately 150 metres below surface. A recently reported drill hole in Kansoko Sud intercepted 15.7 metres (true width) of 7.04% copper, at a 1.5% total copper cut-off.
