Profile Summary. Australian Silica Quartz Group Ltd, formerly Bauxite Resources Ltd, is focused on the acquisition, exploration and development of bauxite minerals deposits in Western Australia. The Company''s projects include Darling Range Project, Athena, Dionysus and Ceres. The Darling Range is a bauxite mining and alumina refining region.
Silica is found in nature in the form of hard rock quartz and naturally weathered sand. It is one of the most plentiful naturally occurring minerals on the Earth. Naturally occurring high grade silica sand is, however, relatively rare and it is this high grade silica that the company is targeting.
What is Quartz? Quartz is a chemical compound consisting of one part silicon and two parts oxygen. It is silicon dioxide (SiO 2).It is the most abundant mineral found at Earth''s surface, and its unique properties make it one of the most useful natural substances.
Most of the known commercial silica (SiO2) deposits in Victoria are mineral sands and gravels of Tertiary and Quaternary age. Small deposits of quartz cobbles, orthoquartzites, silcretes and vein quartz have also been worked. Industries using silica are well established in Victoria. The main use of silica sand in Victoria is in the building
Australian Silica Quartz Group Ltd (ASQ, formerly Bauxite Resources Limited) is an Australian company focusing on the exploration and development of bauxite and lithium mineral deposits in Western Australia. Former Names. Bauxite Resources Limited (BAU), 20/11/2019. Corporate Details.
Silica is silicon dioxide, a naturally occurring widely abundant mineral that forms the major component of most rocks and soils. There are noncrystalline and crystalline forms of silica. Crystalline silica is also known as free silica. Crystalline silica dust particles that are small enough to penetrate deep into the lung are termed respirable.
Galalar Resource. Based on aircore drilling programs, an initial Inferred Resource of Mt of high purity silica sand was estimated in August 2018 by Ausrocks Pty Ltd. The resource was upgraded in March 2019 to Mt of high purity silica sands following additional air

Silica (SiO 2) naturally occurs as the mineral quartz, or silica sand and is a major component of many igneous and sedimentary rocks. Silica can be found naturally in a number of forms as a hard rock quartz vein or reef, as quartz pebbles, or as sandstone, quartzite, or as sand. Excluding sand and gravel that is used in the construction industry,
Silica. Silica (silicon dioxide, SiO 2) occurs as the mineral quartz, a major constituent in many igneous and sedimentary rocks, and the most common detrital mineral in sandstone. As a commodity, the term silica is applied to quartz in all its forms as vein or reef quartz, quartz pebbles, sandstone, quartzite, or as unconsolidated sand.
14/11/2019#0183;#32;According to the NMI database, the total reserve/resources of quartz and silica sand in the country is projected to be around 3, million tonnes. Out of this, million tonnes (17%) are placed under the reserved category. Another 3, million tonnes (83%) are placed under the remaining resources category.

resources are of low, unclassified, others and notknown grades (T able 2). EXPLORA TION amp; DEVELOPMENT Exploration for quartz and silica minerals was conducted by 1) GSI, DMG, Rajasthan 2) and GMDC. Details of exploration carried out for quartz and other silica minerals during 201213 are given in Table 3.
RESOURCES As per the UNFC system as on, the total resources of quartz and silica sand in the country are estimated at 3,499 million tonnes out of which 12% 429 million tonnes are placed under reserves category, while 88% 3,070 million tonnes are placed under remaining resources category.

Silica Quartz. Quartz Quartz is the most abundant silica mineral. Pune Quartz is colorless and transparent. It occurs in most igneous and practically all metamorphic and sedimentary rocks. It is used as a component of numerous industrial materials. Quartz is mainly made up of silica. The formula for it is SiO2. It has a hardness of 7 on the Mohs scale.
Silica is a common naturally occurring mineral, also known as silicon dioxide. One common type of crystalline silica is quartz. Silica can be found or manufactured in different forms, broadly divided into crystalline and noncrystalline (amorphous). This information focuses on respirable crystalline silica, which is the more hazardous form.
Harmful effects of silica. Silica or silicon dioxide (SiO2) is a very common mineral. It occurs in many products including sandstone, concrete, brick and engineered / manufactured stone. Silica is also known as quartz, tripoli and cristobalite.
