According to the characteristics of the raw ore, the use of stage grinding and stage separation technology is an effective measure for energy conservation in iron ore concentrators. At the coarser one stage grinding fineness, high efficiency beneficiation equipment is used to advance the tailings, which greatly reduces the processing volume of the second stage grinding.
Rio Tinto has awarded a contract to engineering company Scott Technology to provide equipment for a sample preparation and analysis laboratory at the Robe Valley iron ore mine in Western Australia. The Robe Valley project is situated nearly 140km south west of Karratha in the Pilbara region.

Reliable equipment to handle the large volumes required in your iron ore mine. For the large volumes of iron ore you produce every day, you need proven and reliable equipment to sustain or increase your production level and avoid unplanned stops. Automation, digitalization and use of the latest technology in everything from bulk materials handling stockyard machines to crushers, screens and samplers give you the highest throughput with less manpower.
Summary: The run of mine ore processing consists of crushing and wet screening to reduce the ore to 6 mm size. Gravity separation methods, employing jigs, spirals and hydro classifiers, are utilized to upgrade coarse fractions. Materials below 0.1 mm are separated by wet high intensity magnetic separators .
As will be argued in more detail below, these practices were basically identical to those used in colonial America. In effect, mining is the extraction of an ore or minerals, for example iron ore, from the earth, generally by means of tunneling or excavation.
This saves mining operations multiple millions in USD every month since iron ore beneficiation increases significantly the costs per ton of ore. Control of the moisture content on the mining conveyor belt together with accurate monitoring of the composition of iron ore before shipment guaranties constant ore quality to avoids penalties.
