"Cost Savings By Rationalisation" ENGINEERING | CONSTRUCTION | ELECTRO TECHNOLOGY | AUTOMOTIVE | INFO TECHNOLOGY | CAREER READY | P-TECH MCE we are always looking for ways to reduce costs to our customers business. One area we have identified as a major cost benefit is rationalising your conveyor pulleys. Working with a major mining house in the Bowen Basin we completed a complete pulley audit, reviewed all GA drawings, checking dynamic and static reports for each location. The review process identified a few issues with the most common one being under designed shafts allowing too much deflection at the locking elements. The engineering design calculations worked on a worst-case installation for each pulley size, considering belt wrap angle and the tensions for the location. Shaft designs were designed to AS 1403 and calculations completed to select bearing size, locking assembly styles and shell thickness. ENROL NOW for Year 10 or Year 11 Contact the Industry Team for more What we found was that in most cases the shaft diameter at the locking assembly needed to be increased to limit the deflection. JANUARY 2019 Start information about training programs This was supported by recent failure of the locking assemblies at the site. Some pulleys required an increase in diameter to limit the stress in the shell with others increasing the shell OD was found to be the most viable way to limit the stress in the shell.

  • Commonwealth of Australia Select Committee on Jobs for the Future in Regional Areas
    Commonwealth of Australia Select Committee on Jobs for the Future in Regional Areas 6 September 2019 Julia Creek | McKinlay Shire Council 1 Introduction This report is McKinlay Shire’s response to the Senate Commission’s request to provide information and insights into the future of jobs and employment opportunities in regional Australia. The report highlights several of the past, current and future challenges in regards to employment the rural community of McKinlay Shire faces. It also addresses opportunities and the need to diversify the activities to ensure continued investments in the local community. Employment opportunities have to be supported by a sustainable base of locals that is able to supply sufficient labour. In other words, population attraction and retention and renewability are essential to sustain local economic development. However, as a remote outback Shire, the forecasts of population growth are negative even in the best-case scenarios. Combined with the existential threat of natural disasters, the high levels of reliance on two volatile sectors, and sheer size of the Shire, potential investments come with a high cost and high-risk connotation which may limit private investment. In order to retain population, Council and other stakeholders should take away or reduce barriers that lead to limitations. Primary services like housing, health care, education and employment opportunities are essential in facilitating people to stay – or least preventing them from having to leave. The outback itself is appealing enough for people to stay or come and live there. As a resources and agriculture orientated Shire, we are vulnerable to external forces and threats that are beyond our control.

Signature of Supervisor Date i ABSTRACT Over the past 15 years, significant sectors of the mining industry have undertaken the Global Mining Initiative. This was followed by an extensive program called the Mining, Minerals and Sustainable Development Project. These self regulatory mechanisms require 'beyond compliance' environmental behaviour, whether companies are operating in the developed or the developing world. Reviewing case studies of gold mines operated by the 'top tier' transnational mining companies in Queensland, Papua New Guinea and Tanzania, this thesis addresses whether these and other self regulatory mechanisms are more important than formal legislation in motivating compliance with environmental laws for these mining companies. iii ACKNOWLEDGEMENTS I would like to sincerely thank and acknowledge the many hours spent by my Principal Supervisor, Associate Professor Geoff Cockfield in developing this thesis. Dr Cockfield‘s erudite comments and suggestions were of immense value.

Wallace, international data coordinator. For the third consecutive year, the difference between the Production high and low prices for silver was less than $1.00 per troy ounce. This small movement in price occurred at a time when In 2001, silver was produced in the United States from global fabrication demand for silver decreased by 5% to 26,900 precious metal ores at about 30 lode mines and from base metal metric tons (t). Most of the decrease occurred in industrial ores at about 24 lode mines. More than 30 t of silver was demand, declining by more than 10% to 10,500 t. Global produced at each of 11 mines; their aggregated production photographic demand was only slightly lower, while demand equaled about 80% of total domestic production.

  • A Technique for Tracking Multiphase Mineral Particles in Flotation Circuits
    XXII ENTMME / VII MSHMT – Ouro Preto-MG, November 2007. A TECHNIQUE FOR TRACKING MULTIPHASE MINERAL PARTICLES IN FLOTATION CIRCUITS Pertti Lamberg and Sergio Vianna Julius Kruttschnitt Mineral Research Centre (JKMRC), Isles Road, Indooroopilly, Brisbane, Australia E-mail: [email protected] ABSTRACT The relevance and value of liberation analysis for plant design and optimisation is well established. However, especially in flotation, the use of liberation information provided by image analyser systems such as the JKMRC Mineral Liberation Analyser (MLA) and QEMSCAN, has been largely concentrated on deportment (or losses) studies of valuable minerals in circuits. In addition, in all data presentation packages, liberation data are presented in a simplified fashion where multiphase particles are treated as binaries (i.e. valuable mineral plus other minerals lumped together). A more robust and rigorous approach for diagnosis, modelling and optimisation of circuits is to perform liberation analysis considering all mineral phases in particles. To this aim, a systematic methodology has been developed for reconciliation of multiphase particles. The method consists of seven steps aiming to minimize the error propagation of liberation data. The steps are as follows: 1) unsized mass balance, 2) size-by-size mass balance, 3) conversions from elemental assays to mineral quantities, 4) liberation data reconciliation, 5) particle classification and binning, 6) smoothing of liberation data, 7) mass balance of particle classes (i.e. liberation mass balance of multiphase mineral particles). The methodology has been successfully applied to flotation tests of a high-grade lead-zinc-silver ore from BHP-Billiton’s Cannington mine in Australia. The limit of the technique is discussed.
