Heavy mineral sands are extracted by dredge (Figure 8), bucket-wheel excavators or draglines, and bulldozers. The raw material is then processed, first by gravity concentrators, to remove light minerals; the concentrate is scrubbed and dried, ilmenite, leucoxene, and rutile being removed by magnetic and high-tension techniques ( Figure 9 ).

To extract other minerals, the -1 mm table concentrate is typically refined by heavy liquid (methylene iodide) separation to produce a heavy mineral concentrate (“HMC”). The density of the heavy liquid can be modified to any specific gravity depending on the targeted mineral.

The extraction reached equilibrium rapidly, after about 30 min. A 0.01 M EDTA solution was less effective than a 0.05 M or a 0.10 M EDTA. EDTA was proved to be effective for metal removal from the four individual soil fractions and synthetic soils. In general, approximately 90% of metals were removed from synthetic soils by 0.10 M EDTA.

2009-8-26 Mineral Processing Upon arrival at the mineral separation plant, located at the smelter site, the heavy mineral concentrate is re-slurried and pumped into the feed preparation circuit. Here the slurry is passed over successive stages of low- and high-intensity magnets to remove the ilmenite that is set aside as feedstock for the smelter.1

2021-5-20 Heavy minerals are separated from light mineral sands (i.e., silica sand and clay) using gravity (see Figure 1). Extraction of heavy minerals have various other characteristics, which enable mining and processing to be carried out by responsible operators in a manner that results in minimal environmental impact.

The heavy mineral sands of Senegal are exploited to extract titanium oxides and zircon. Mining is carried out first by means of a floating dredge and concentration plant which produces a heavy mineral concentrate (HMC) containing on average 78% titanium oxides, 11% zircon and a set of silicate and alumino-silicate minerals. This heavy mineral concentrate is then treated by gravity, magnetic ...
