First, raw materials are sent to the vibrating feeder through hopper, crusher for gold mining then they are fed into rock jaw crusher evenly and continuously. After crushed by zirconite mobile jaw crusher, materials are then sent into rock impact crusher where it will be transferred to secondary ZYS cone crusher, which makes cubical shaped product. After second crushing, materials are sent to vibrating screen which will separate different products according to your requirements. While those particles haven’t attained the required fineness will be returned to illite mobile impact crusher for tertiary crushing. We deploy suitable model equipment, and develop its optimum behavior according to different technical requirements.
All of Hamersley Iron’s mines are standard open pits. Material is drilled and blasted in benches, quartz sand processing blast holes getting charged with an ammonium nitrate/fuel oil (ANFO) mixture and heavy ANFO dispensed by bulk explosive trucks. Ore is loaded into haul trucks by shovels, hydraulic excavators or front-end-loaders, and transported for the main crusher. It really is then processed in a crushing and screening plant to create fine ore and lump ore.
At Marandoo, four pits are operational and others will be brought into operation inside the future.
The low bench height (10m), compared with Mount Tom Value (15m) and Paraburdoo (14m), facilitates selective mining and minimises dilution, coal handling plant but equipment is smaller than at Hamersley’s other operations.
Brockman enhances the stability and flexibility of Hamersley operations and raises the proportion of lump in Hamersley’s item mix. It’s a contractor operation with management and grade manage coming below Hamersley’s direction. The deposit consists of detrital and conglomerate haematite.
At Channar, crusher feed comes from Channar Main Pit and Channar East, with Paraburdoo’s contribution to total production getting been lowered accordingly to retain continuous output as Channar’s has built as much as more than 10Mt/y.
