DEWATERING OF IRON ORE MINES AND CAPABILITY TO

2005-11-1  The Cauê Formation, that hosts the iron ore reserves, consists of (oxide facies) banded iron formation formed by (1 mm to 1 cm thick) bands of iron oxides intercalated with bands (with similar thickness) of quartz and/or dolomite, named Itabirite in Brazil. The fresh rock (protore) averages 35 – 45% Fe. Its origin is sedimentary chemical.

Ultra scale‐down device to predict dewatering levels

2013-10-1  To alleviate the need of pilot‐scale trials, a novel USD device, with reduced amounts of feed (2 mL) and to be used in the laboratory, was developed to predict the dewatering levels of a SDC. To verify USD device, dewatering levels achieved were plotted against equivalent compression (Gt comp ) and decanting (Gt dec ) times, obtained from scroll rates and feed flow rates operated at pilot‐scale,
