In the present study, effects of several operating parameters on the separation efficiency of mica from feldspar by spiral concentrator were investigated. For this purpose, an albite ore containing mica was treated in a full scale Reichert spiral (model HG7) under various test conditions. During the study, particle size distribution, solid contents of the feed, feedrate and splitter position were changed. It was observed that in a spiral concentrator mica could be separated from feldspar owing to its laminar morphology. Accordingly, it was found that particle size and solid contents had significant effect on the separation. Best results were obtained with feed solid content of 15% by weight for the particle size fraction of -212+74 mm. In line with this, Fe2O3 content, which was 0.71% in the feed, decreased to 0.07% in concentrate.
