Fine Particle Processing of Some Indian Iron Ore Slimy
01-02-2017 Restriction in production of ore and Closing down Iron ore mines, spurred the mines to look for alternative routes like processing of BHQ/BHJ waste rock or processing of iron ore slimy plant tails. The latter route was logically and scientifically attractive as pellet grade concentrates may be produced at low cost with a possibility of partial reclamation of tailing pond area and mitigating

Treatment and Recycling of the Process Water in Iron Ore
The annual processing capacity of iron ore reaches 22 million tons, and the wastewater from mineral processing is about 400 thousand m 3 every day. If the dressing wastewater is directly discharged into the nature, it will not only pollute the surrounding environment but also has a great potential safety risk.

Effects of iron-ore mining and processing on metal
For the first time in the tropics, we identified the effects of iron-ore mining and processing on metal bioavailability in a coastal lagoon. With an extensive sampling scheme, we investigated the potential sources of metals; the links among metal levels in water, sediments, and invertebrates; and the contrasting effects on metal speciation and bioavailability.

Managing ore variability in iron ore processing
By Keith Vining. CSIRO can help you manage unplanned processing incidents. At Iron Ore 2017, a common concern across the industry was managing the short-term variability of ore characteristics within deposits in iron ore processing, the flow-on effects of unplanned processing issues, and the resulting downtime across the production cycle.
