ticles that belong in either the concentrate or the tailings, are also produced, further complicating the situation. Roughing is the upgrading of the ore (referred to as feed in the concentration process) to produce either a low-grade, pre-liminary concentrate, or to reject tailings that contain no valu-able material at an early stage.

BeltSense™ – MineSense


BeltSense can be used sequentially and in conjunction with ShovelSense to maximise the ore concentrating impact, taking a first cut at the haul point and second further downstream. Use case evaluation by MineSense determines how much of the total value can be captured by one platform versus two and at which point in the process.

Effect of Iron Ore Concentrate on Sintering Properties


The portion of −20 µm in iron ore concentrate favoured the granulation and the productivity in conventional sintering, but the portion of +45 µm had the reverse effects. With increases in finer commercial concentrates (10–40 mass%) combined with low grade ore (10–20 mass%) in iron ore blends, the productivity also did not obviously change.
