Lowering respirable dust at an iron ore concentrator …
This change accounted for a 31 pct reduction in respirable dust levels in the primary grinding area of the mill. Another successful modification was to improve the sealing of a reclaim tunnel to the outside and by barricading the access point from the reclaim tunnel to the concentrator plant. This mini-mized the dust liberated in the conveyor ...
Nimba (Yekepa) Phase 2 iron ore mine
Operating costs will rise significantly as the DSO operation winds down and the concentrator ramps up. Phase 1 and 2 combined have a total capital cost of US$2.3 billion, which translates to a capital intensity of US$153/tonne. With the transfer of the Nimba Iron ore project, the miner now holds a virtual monopoly.
