For example, in Newcrest's Telfer gold mine, the regrinding of copper rougher concentrates significantly improves copper and gold recoveries in the subsequent flotation (Seaman et al., 2012). The small grain size of the valuable minerals in highly disseminated ores requires fine grinding to provide sufficient mineral liberation.
Isa Mill In Canada Copper Plant As Regrinding Copper Mountain Announces New Life Of Mine Plan 1 day ago018332The above costs result in an average C1 cash cost per pound of copper of for the first ten years and over the life of mine, net of byproduct credits.. Read On.
Traditional finegrinding mills in mineral processing rely on the use of steel medium for particle size reduction. The IsaMill (a horizontal stirred mill with a 3,000L net chamber volume and a rated motor power of 1,120 kW) has successfully adopted a novel productseparator design, which has led to a major revision of medium use in fine grinding. The IsaMill separator has successfully ...
To ensure adequate mineral liberation is achieved ahead of the dilution cleaner circuit, a regrind mill is installed on the combined copper rougherscavenger concentrate stream. See below the mineralogically limiting grade recovery chart, summarizing the theoretical limits to metallurgy imposed by the mineralogical associations in the cleaner circuit streams: Regrinding of the copper rougher ...

Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or largescale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.

To identify whether any alteration of the pyrite surface occurred after the addition of copper ions during regrinding, mill discharges after regrinding were subjected to XPS measurements. Table 3 shows the atomic concentration of O, Fe, S and Cu on pyrite surfaces. Fig. 10, Fig. 11 show Cu 2p and Fe 2p XPS spectra, respectively.
In recent times, a low copper content in ores has been observed (ores containing % copper are used for processing in Canada and the United States, and ores containing at least % copper are used in Russia []) owing to the exhaustion of rich copper flowsheet of processing copper ores is developed for each particular ore, but there are some general trends in the choice ...
Also, equipment like ball mill is used at the final stages of grinding. Among the comminution and grinding equipment, HPGR is increasingly utilized as tertiary crusher or primary mill because of ...
Concentrator Operations. The ores received into the plant, after conventional washing, crushing and grinding, are subjected to differential flotation for the recovery of sulphide copper mineral for smelting and oxide (or nonsulphide) copper minerals for leaching. Sources of feed materials to the concentrator are: (a) Nchanga West orebody.
The control of a milling operation is a problem in imponderables: from the moment that the ore drops into the mill scoop the process becomes continuous, and continuity ceases only when the products finally come to rest at the concentrate bins and on the tailing dams. ... An example of the last is a leadcopperzinc ore containing also gold and ...
The concentrations were strongly linearly related (r² = ), indicating sample contamination during grinding through a stainlesssteel hammer mill. We tested this hypothesis in two ways. First ...
In Brazil, during the last 10 years, regrind P80 sizes of approximately 40 to 20 μm have been necessary in all new iron and copper plants. The use of conventional ball mills, adequate for primary ...

Flotation data for the design of process plants Part 2 case studies R. C. Dunne*1, G. S. Lane2, G. D. Richmond3 and J. Dioses2 The Cadia Hill Gold Mine and the Hellyer copper, zinc and lead plant present different problems with widely different target grind sizes, liberation characteristics. The contrast is between Hellyer s
This paper describes an investigation in the Mt Isa Copper Concentrator to identify the potential cause of periods where grade or recovery was below target values. ... Comparing the mineral recovery by size performance of the plant with baseline data from a previous plant survey identified much higher recovery of fine iron sulphides as the ...

(Laboratory Work) 1. 198990: Initial stage, regrinding to 15 µm (ball mill, inert media). Evaluation of concentrate quality (marketing study) must regrind to 7µm. 2.
The IsaMill is a stirredmedium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older highthroughput mills (such as ball mills and rod mills ). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill. [7]
The regrinding of some streams within flotation circuits, to liberate valuable mineral attached to gangue, is a common practice. However, the methodologies proposed for flotation circuit design based on optimization, usually, do not consider regrinding. This work analyzes the effect of the uncertainty in flotation and regrinding stages on the ...
