  • Telfer Processing Plant Upgrade – the Implementation of Additional
    Telfer Processing Plant Upgrade – The Implementation of Additional Cleaning Capacity and the Regrinding of Copper and Pyrite Concentrates D R Seaman1, F Burns2, B Adamson3, B A Seaman4 and P Manton5 ABSTRACT The Telfer concentrator, located in the Great Sandy Desert of Western Australia, consists of a dual train gold/copper operation processing ore from one underground and, currently, two open pit mines with differing mineralogy. The fl otation circuit of each train was designed to operate in several modes depending on the feed mineralogy. The majority of ore mined at Telfer is processed in a sequential mode where copper minerals are fi rst fl oated into a saleable copper concentrate followed by the fl otation of an auriferous pyrite concentrate which is treated in an on-site hydrometallurgical plant (carbon-in-leach (CIL)). Gold is recovered as a gravity product within the primary grinding circuit, to the copper concentrate, and to a lesser extent, the CIL circuit. Since Telfer was re-opened, with a new concentrator, in 2004, the processing plant has struggled with poor copper concentrate grades, partially due to the excessive entrainment of non-sulfi de gangue minerals in the copper fl otation circuit and, more recently, due to composite copper particles produced when processing ore from a supplementary satellite pit that has not previously been processed through the new Telfer concentrator. Gold recoveries in the CIL circuit have also been below industry standard. This paper presents the implementation of recent changes made to the circuit to address these performance issues. The reconfi guration of the circuit has involved the installation of the following major equipment items: two ISAMills™ in ultra-fi ne grinding applications (one in the copper circuit and one in the pyrite circuit), two Jameson Cells to improve fi ne gangue rejection and a bank of 5 × Outotec TC30s to recovery copper and gold from the reground pyrite stream.

  • Scale-Up in Froth Flotation: a State-Of-The-Art Review
    Scale-up in froth flotation: A state-of-the-art review Diego Mesa∗, Pablo R. Brito-Parada Department of Earth Science and Engineering, Royal School of Mines, Imperial College London, South Kensington Campus, London SW7 2AZ, United Kingdom Abstract Froth flotation has been one of the most important and widely used methods to concentrate minerals since its introduction over a hundred years ago. Over the last few decades, in order to process more mineral while reducing capital costs, flotation equipment has become exponentially larger. The increase in tank volume, however, has brought new challenges in the operation and design of industrial flotation tanks. This review analyses the literature on flotation tank scale-up for the first time, contrasting several techniques and approaches used in both historical and state-of- the-art research. The study of flotation scale-up is crucial for the optimisation of industrial plant performance and the maximisation of laboratory-scale research impact. While important advances in our understanding of flotation have been achieved, large flotation tank design and scale-up has, to a large extent, remained in-house know-how of manufacturing companies. This review of the literature relevant to flotation tank scale-up has resulted in a new classification, dividing the scale-up literature into two main areas of study, namely \Kinetic scale-up" and \Machine design scale-up". This review indicates that current scale-up rules governing the design of flotation tanks focus mainly on pulp zone kinetic parameters and neglect the effects on the froth zone, despite the importance of froth stability and mobility in determining flotation performance.

  • Flotation of Sulphide Ores - HZL Experience
    FROTH FLOTATION : RECENT TRENDS @IIME, JAMSHEDPUR, 1998; pp. 18-41 Flotation of Sulphide Ores - HZL Experience V.P. KOHAD Hindustan Zinc Ltd., Zawar Mines, Udaipur - 313 901 ABSTRACT Flotation process, patented in the year 1906, was originally developed for mineral industry to recover values from high grade tailings of gravity separation plants. This technology has acclaimed importance as a versatile process for the beneficiation of vast variety of sulphide minerals. Due to flexibility of the process and remarkable development taken place in flotation technology and its ancillary systems, it has now become possible to recover fine grained sulphide minerals from complex ore deposits, whose processing was earlier considered un- economical. Today, about 400 million tonnes of sulphide ore is treated annually by flotation process worldwide. M/s Hindustan Zinc Ltd. (HZL), a leading lead-zinc mining and smelting company in India has experienced a spectacular growth from the time of its inception. Starting from a single 500 MT per day lead-zinc mine at Zawar, HZL has expanded its mining capacity to about 13,000 MT per day with matching ore beneficiation plants, all adopting froth flotation technology. The phenomenal progress is a result of HZL's emphasis on research and development with an objective to improve the efficiency and to optimize performance, and to seek innovative modern technology and control systems in their flotation plant and processes. This has not only solved metallurgical problems but improved overall plant economics. High grade concentrates produced with reduced deleterious impurities have further enhanced smelting efficiency. The paper covers general principles and aspects of industrial sulphide ore flotation practices in brief and processes adopted in HZL's plants.

  • Economic Recovery and Upgrade of Metals from Middling and Tailing Streams
    ECONOMIC RECOVERY AND UPGRADE OF METALS FROM MIDDLING AND TAILING STREAMS *P. Voigt1, M. Hourn1, V. Lawson1, G. Anderson1, and D. Mallah2. 1Glencore Technology 160 Ann St Brisbane, Australia 4000 (*Corresponding author: [email protected]) 2Glencore Zinc PMB 6, Mount Isa Queensland, Australia, 4825 ABSTRACT As mine head grades decline and orebodies become more complex, traditional mineral processing techniques and flowsheets to achieve saleable concentrate become more difficult to design and construct. Mines with lower quality concentrates or concentrates with penalty elements are particular under threat. The economics of these operations are far more susceptible to metal price, concentrate treatment terms and the availability of other, cleaner concentrates. Additional value may be realised for these orebodies through improved recovery by producing a low grade middling concentrate for further processing, in conjunction with a saleable concentrate. The most cost effective way to reduce impurity levels is to do so as early as possible in the mining value chain. Technologies such as fine grinding and fine particle flotation are well established as effective methods for impurity rejection in mineral processing. What is normally overlooked is how a hydrometallurgical process could also be integrated in the overall flowsheet to achieve higher overall recovery at the mill. In the base metals environment, this is mainly because hydrometallurgical processes are associated with production of metal or use of expensive and toxic precipitating agents once the minerals of interest are solubilised. These processes can be very expensive, particularly with rising power costs and poor economies of scale in capital costs associated with low production rates from middling streams.

  • Recovery Interactions Between the Froth Zone, Pulp Zone and Downcomer Within a Jameson Cell
    RECOVERY INTERACTIONS BETWEEN THE FROTH ZONE, PULP ZONE AND DOWNCOMER WITHIN A JAMESON CELL G Harbort(1), J Cowburn(2), E Manalpig(3) (1) University of Queensland (2) Xstrata Technology (3) Julius Kruttschnitt Mineral Research Centre ABSTRACT The work reported in this paper shows that the primary area of coal recovery within the Jameson Cell is the downcomer, where the air and pulp are dispersed into a dense foam of fine bubbles. This creates an intense collection zone for bubble-particle collision and coal collection. Historically, coal recovery in the Jameson Cell has not differentiated between recovery in the downcomer, pulp zone or the froth zone. As such, attempts to optimise the recovery of coal in one zone can result in non-optimum performance of another. A major flotation programme has been undertaken to measure coal recovery in the three zones of the Jameson Cell, separate from each other. The findings from this work should allow, upon completion, recovery in each zone to be individually optimised to give maximum overall coal recovery, from a size by size perspective. INTRODUCTION The Jameson Cell was a joint development between Mount Isa Mines and Prof. Graeme Jameson of the University of Newcastle (Jameson, 1988). Since its invention in 1986 there have been 94 Jameson Cells installed in the coal industry, both in Australia and overseas. Jameson Cell operation The principles of Jameson Cell operation have been discussed by numerous authors, including Jameson et al (1988), Evans et al (1995) and recently by Harbort et al (2002). The Jameson Cell can be divided into three main zones, as described with reference to Fig.
