Iron ore enrichment by spiral separator
WebThe low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well … WebApr 3, 2014 · Size fraction of the iron ore used for jigging is 0.5 mm to 30mm. Spirals – Spiral concentrators are flowing film separation devices. General operation is a continuous gravitational laminar flow down on an inclined surface. The mechanism of separation involves primary and secondary flow patterns.
