Spiral Concentrator - Outotec

Heavy minerals such as ilmenite or hematite settle out rapidly in a spiral concentrator and they should be removed as soon as a good wide band forms. Since the concentrate band is wider at the top, splitters near the top of the spiral concentrator should be opened wider than those near the bottom.

Mineral processing - Wikipedia

Analysis of the feed to several plants revealed that the material finer than 44 µm (325 mesh) and even 70 µm (200 mesh) was usually very high in ash content (>30 %) with a considerable amount of superfine size clays. Due to the high ash content and the poor dewatering ability of the minus 44 µm coal when recovered, it became viable to consider completely discarding this size fraction. It is ...
