Mineral sands - Earth Resources
Mineral sands contain suites of economically important minerals of high specific gravity known as ‘heavy minerals’. These include minerals rich in titanium, zirconium and rare earth elements that are found in very low concentrations in a variety of igneous and metamorphic rocks.

The calculation of resource volumes for large mineral sands deposits is the process of systematically compiling all known data in order to define the volume of ore contained and its intrinsic economic value. Traditionally, this process has been highly speculative in nature, as the layer thickness between even closely-spaced boreholes can be highly variable. The …
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.

The importance of exploration Exploration activity is fundamental to the future success of the Australian mining industry. Exploration is the process by which geological information is collected and analysed to identify mineral deposits as well as determining the economic feasibility of their extraction.
Placer deposit - Wikipedia
In geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. The name is from the Spanish word placer, meaning "alluvial sand". Placer mining is an important source of gold, and was the main technique used in the early years of many gold rushes, including the California Gold Rush.

Mineral sand deposits are formed from the erosion and weathering of pre-existing igneous rocks such as granite, pegmatite and basalt. Over 60 to 200 million years the combinations of wind and water from ancient rivers and seas have leached the minerals from their past rocks and concentrated them into beach and dune deposits.

There is significant opportunity to rapidly add value through low cost exploration activities over areas of known heavy mineral sand (HMS) mineralisation to discover large tonnage, high grade sweet spots and high unit value resources. The potential exists for a long mine life mining asset under a number of staged mining and process scenarios.

Mining minerals from sand
Mining minerals from sand Learning objectives By completing this activity, you will: • Use ilmenite (a mineral which contains the element titanium), which is mined by DuPont to use as a white pigment, as an example of a mineral resource formed by sedimentary processes. • Summarize the processes that act to make clastic sedimentary rocks.
