Heavy mineral sands (HMS) have great economic interest. They are exploited to extract mainly minerals such as titanium oxides (ilmenite, rutile and leucoxene), and zircon. In some mining operation, monazite (Ce, La, Nd, Th) PO 4 is also recovered as a by-product. It is a mineral which therefore contains rare earth elements.

Titanium minerals occur in alluvial and volcanic formations. Deposits usually contain between 3 and 12 percent heavy minerals, consisting of ilmenite, rutile, leucoxene, zircon, and monazite. Mining and concentrating. Although workable known reserves of rutile are diminishing, ilmenite deposits are abundant. Typical mining is by open pit.

It can be seen that high-gradient magnetic separation plays a crucially important role in the recovery of fine ilmenite from the ore. In the flowsheet as shown in Figure 21, the feed is firstly processed by wet low-intensity drum magnetic separation to concentrate vanadic titano-magnetite, and then is effectively processed through an SLon pulsating high …

Flotation tests showed that Al 3+ promoted ilmenite up-floating, and a maximum recovery of 86% could be achieved using the Al-BHA complexes at pH = 8. Zeta potential and adsorption tests illustrated that the introduced Al 3+ activator was adsorbed on the ilmenite surface, and the pre-formed Al-BHA complexes could stabilize BHA …

In sand mining operations, the ore is recovered by floating dredges ("wet mining") or by bulldozers and scrappers ("dry mining"). As shown in Fig. 3.6, the sand is usually fed to a "wet concentrator" or "primary concentrator" to produce heavy minerals concentrate (HMC), which is a mixture of ilmenite, rutile, magnetite, zircon ...
