Abstract

Abstract

There is a beach placer ore abroad, which is rich in ilmenite, zircon, monazite and other valuable minerals. Oxidation alteration of ilmenite and some contaminated zircon surface with iron change the magnetic and electrical properties of the minerals, which makes it difficult to separate. In view of the complex characteristics of raw ore, a process of sieve and one rough-one sweep with spiral chute was carried out to enrich the heavy minerals in a 23.78% yield concentrate, in which the grade of Fe, TiO₂, REO and Zr(Hf)O₂ were 25.76%, 43.73%, 0.44%, 2.83%, while the recovery were 93.70%, 93.11%, 78.32%, 93.64%, respectively. Based on the heavy minerals concentrate, a process including low-intensity magnetic separation of iron, then one rough one fine and one sweep with high-intensity magnetic separation (WHIMS) was applied to separate ilmenite and enrich monazite. Part of stronger magnetic ilmenite was separated in WHIMS final concentrate, monazite and another part of weaker magnetic ilmenite in WHIMS middling were separated by a process of table separation, dry magnetic separation and high-tension separation. Zircon in WHIMS tailings was separated by a process of table separation and then high-tension separation for impurities removal of rough zircon concentrate. The separation of magnetite concentrate, ilmenite concentrate, monazite concentrate and zirconium concentrate were finally achieved. The total TiO₂, REO and Zr(Hf)O₂ recovery rate of heavy minerals concentrate were 99.16%, 67.71% and 89.56% respectively. The comprehensive recovery of valuable minerals was realized. This research could be a reference for the exploitation of similar beach placer ores.
