world production trend of zirconium mineral concentrates
zircon common accessory trace mineral constituent of granite , felsic igneous rocks. due hardness, durability , chemical inertness, zircon persists in sedimentary deposits , common constituent of sands. zircon rare within mafic rocks , rare within ultramafic rocks aside group of ultrapotassic intrusive rocks such kimberlites, carbonatites, , lamprophyre, zircon can found trace mineral owing unusual magma genesis of these rocks.
zircon forms economic concentrations within heavy mineral sands ore deposits, within pegmatites, , within rare alkaline volcanic rocks, example toongi trachyte, dubbo, new south wales australia in association zirconium-hafnium minerals eudialyte , armstrongite.
australia leads world in zircon mining, producing 37% of world total , accounting 40% of world edr (economic demonstrated resources) mineral. south africa africa’s main producer, 30% of world production, second after australia.
