Figure 1.5.3 shows the distribution of major historic and existing mineral sand operations in Australia. Light rare-earth elements in mineral sand deposits represent very large resources that may be exploited in the future. The rare-earth elements and thorium in these deposits are mainly locked up in monazite and are not currently extracted.

The source materials of heavy mineral sand are metamorphic and igneous rocks. Metamorphic rocks give rise to sand containing kyanite and garnet, for example, although the latter may crystallise from magma as well. Magnetite is mostly of igneous origin. Heavy mineral sand is a natural mineral concentrate which is often mined commercially.

Mineral sand deposits in the Murray Basin offer the potential for significantly expanding Australia's production of ilmenite, rutile and zircon. Since prices of zircon and rutile are higher than ilmenite, and zircon grades in most deposits are significantly higher than those for rutile, zircon often is the major economic mineral component in mineral sand deposits. Two types of deposits occur ...
