Order for new REFLUXTM Classifier technology

FLSmidth secures order for new REFLUXTM Classifier technology for treatment of iron ore fines in Norway. Rana Gruber operating an iron ore mine and concentrator close to the Arctic Circle in Norway decided to order the two REFLUXTM Classifier RCTM-3000-HY-SS units following successful pilot trials. The new REFLUXTM Classifier technology is rapidly gaining popularity in coal and iron ore processing applications around the world because of its high separation efficiency and the ability to easily handle varying feed conditions compared to traditional gravity separation technology.


In the pilot trials at Rana Gruber, the Reflux Classifier technology demonstrated consistent separation and high separation efficiency in the 0-150 µm size fraction from material currently discarded to tailings. While the iron grade of the feed to the Reflux Classifier is around 10 % the concentrate produced by the Reflux Classifier was more than 60 % Fe, and a yield of more than 20 % of the iron in the 0-150 µm size fraction.


Sales Director EMENA, Andrew Dixon, explains the successes achieved with the RCTM technology with greater process flexibility in operation and high recovery compared with available alternatives: “The RCTM incorporates a ‘laminar high shear rate’ mechanism, which represents the latest in fine particle gravity based separation technology. The lamella section enhances the REFLUXTM Classifier’s capacity, producing a more compact, higher efficient separation unit when compared to competing iron ore and mineral processing equipment such as spirals, up-current classifiers and teeter bed separators.”
