Heavy Mineral - an overview | ScienceDirect Topics
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).The remaining minerals are then separated by a system of ...
Heavy mineral sands ore deposits - Wikipedia
Heavy mineral sands are a class of ore deposit which is an important source of zirconium, titanium, thorium, tungsten, rare-earth elements, the industrial minerals diamond, sapphire, garnet, and occasionally precious metals or gemstones.. Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains.
