In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn’t lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do. As it is revolved in the slurry the spiral is constantly moving the coarse backwards the fine material

Most of the heavy minerals including iron ore are treated through gravity concentration process due to considerable difference in specific gravity of ore and gangue minerals. The popularity of gravity concentration is due to their simplicity, low operating cost and ease of operation. Spiral concentrator is the key operating unit and widely used for beneficiation of different minerals and coal

Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). Ores are normally associated with unwanted gangue material. Grade of iron ore is usually determined by the total Fe content in the ore. Run of mines ores after dry or wet sizing, if it

Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore. The beneficiation process should
