Spiral Concentrator

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.

Subsidence of the coast was followed by a process of shore straightening, which caused the formation of along shore sand bars extending from headland to headland. Shore currents moved sands and breakers carried the lower specific gravity minerals into the deep water on the landward side of the bar.

Spiral optimisation at mineral sands plant

Multotec recently optimised spiral concentrators at a mineral sands processing plant in Mozambique to counter the decrease in material head grade the plant was experiencing. Operators at the spiral plant had to close the sliding splitters completely, or open them very conservatively, in order to minimise product contamination. However, with the ...
