Three Springs Talc Ore Sorting Plant Expansion

Como Engineers was awarded the contract to complete the detailed engineering design, supply, construction and commissioning of the expansion of the Three Springs talc ore sorting treatment plant operated by IMERYS Australia Talc, undertaken as an EPC contract. The plant comprises single stage crushing (feed rate 250tph), conveyors, screens, chutes and bins (sourced from Indonesia and Australia), feeding free issued primary and secondary ore sorters. Como Engineers was responsible for all aspects of the works, including earthworks and concrete works, electrical and instrumentation, automation, structural and mechanical. The crushing and screening plants were existing; however, screening required additional screen decks complete with a new discharge chute to separate the ore into >150mm, <150mm to >60mm, <60mm to >25mm and <25mm size fractions. The <150mm to >60mm and <60mm to >25mm size fractions reported to two Tomra optical sorters, from which product and waste streams were separated to shuttle conveyors and consequent stacking.
