In nature silica sand occurs as a crystalline mineral in many and varied forms The most common is quartz commonly clear or white with a Mohs hardness of 7 and a specific gravity of Bruvel 1999 In Malaysia silica sand is important as an exploitable
up and pumped to a floating concentrator At this point the heavy minerals are separated from the sand by exploiting differences in mineral density via a multi stage circuit of A portion of the magnetite and the chromium containing minerals are removed magnetically and the resulting heavy mineral concentrate HMC stockpiled for
Occasionally these deposits are referred to as "beach sands" However mineral sands are also found in large aeolian sand systems or dunal sands The exploration development mining and processing of mineral sands is atypical within the resource sector because at virtually every stage it is possible to visually estimate the grade and
3 The Donald Project will operate 15 km east of Minyip developing a world class mineral deposit discovered in the 1970s The site contains significant reserves of zirconium titanium and rare earth elements including neodymium and praseodymium The land is currently arable and mixed use The Donald Project will generate significant economic and social benefits across
• Mineral soil relative proportion of sand silt and clay • Organic soil based on the degree of decomposition • Structure describes the aggregation of mineral grains into secondary units or peds • May reflect natural pedogenic processes weathering
Among these minerals monazite is a common beach sand mineral present in acidic igneous rocks and vein deposits mainly containing 4 12% ThO2 20 30% Ce2O3 and 10 40% La2O3 Thompson et al 2011 The potential sources of monazite mineral are presented in Table 3 Hedrick 2001

Sand deposits found on beaches or in rivers and streams are mostly quartz silicon dioxide SiO 2 grains Weathering of rocks such as granite forms these quartz grains In the process of weathering the softer weaker minerals in granite such as feldspar are weathered away The more resistant quartz eventually is ground down in size but
Mineral sands have a number of uses including in paints paper plastics sunscreens tiles and joint replacements China is the biggest consumer of mineral sands with Australia being a major producer accounting for 32% of the world s share of ilmenite titanium resources 62% of rutile resources and 68% of global zircon resources
Zircon sand concentrate from South Africa Width of view 12 mm Zircon is very important mineral to geologists Small amount of zirconium is replaced with uranium which is a radioactive element Zircon is a very common mineral in sand These sand grains are small but they are still often easily spotted Euhedral grains tetragonal prisms
