Introduction. Pulsating high gradient magnetic separation (PHGMS) is now widely applied in the world, for separation of fine weakly magnetic ores such as oxidized iron ores, ilmenite and wolframite and for purification of non-metallic ores such as quartz and feldspar, due to its high reliability, high throughput and low operational cost [1], …

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

Gravity separation equipment can effectively handle coarse-grained, medium-grained and fine-grained ores with little mud. It has the advantages of strong adaptability, high sorting recovery rate and low cost. JXSC is a manufacturer of gravity mineral processing machinery. It has professional technical personnel and preferential prices.

In this context, a low-grade hematite ore with 56.5% Fe has been subjected to heat treatment followed by grinding and wet high intensity magnetic separation (WHIMS). The magnetic separation results indicate that an enhancement in yield by around 15–20% by weight is possible when the ore is heat-treated at 500–800 °C.
