New Process Technologies Help Producers Recover More Metal

Rana Gruber, a Norwegian company that operates an iron ore mine and concentrator near the Arctic Circle, recently ordered two of FLSmidth’s Reflux RCTM-3000-HY-SS Classifier units following successful pilot trials.

FLSmidth reported that in the pilot trials conducted at Rana Gruber’s facility, the Reflux classifier technology demonstrated consistent separation and high separation efficiency in the 0–150 micrometer (µm) size fraction from material currently discarded to tailings. While the ore grade of the feed to the Reflux classifier was approximately 10% Fe, the concentrate produced by the Reflux classifier was more than 60% Fe, with a yield of more than 20% of the iron in the 0–150 µm size fraction that is currently lost to waste.
