Mineral Sands | Geoscience Australia

Most sand on the beach consists of grains of the mineral quartz (SiO 2).Mineral sands are old beach, river or dune sands that contain concentrations of the important minerals, rutile, ilmenite, zircon and monazite.These ''heavy'' minerals have a relative density of between 4 and 5.5 g/cm 3 and are much heavier than common sand minerals such as quartz which has a density of around 2.65 g/cm 3.

Sand and Gravel Mining

Sand is usually defined as an accumulation of mineral grains in sizes ranging from one-sixteenth to two millimeters. Sand normally consists predominantly of quartz grains of variable degrees of roundness. Other mineral grains within the sand size range are also present and typically consist of feldspar, chert, ilmenite, and other less abundant resistant minerals. Gravel is considered to be an ...
