The attempted development of the Pine Point white clay for industrial use is described, including percussion boring in 1950 and 1956. The 1956 programme, though not completed because no sale can be found for the clay, shows that approximately 50,000...

This report forms part of a series covering an investigation into the clay resources of South Australia. Washing and cyclone treatment of the clays from Mount Crawford, containing damourite and silliminite, gave a product which may be suitable for the...

The deposit of clay situated on the northern bank of Salt Creek was first recorded by Departmental Prospector, A.S. Giles, in September, 1949. A twenty acre Claim was pegged by the claimholder in 1951 after a proclamation made this land available for...

Fine and coarse clay products, both containing five per cent free silica, were produced by cyclone treatment from a raw kaolin clay containing twenty per cent free silica.

Fine clay products from previous washing tests were treated in an attempt to meet specifications for the paper industry.

Three specimens of kaolin-rich rocks from the Cultana area were examined. One specimen is distinguished by cross-bedded, highly angular quartz and is probably Adelaidean in age. Identification of the other two specimens is uncertain.

This report presents a comprehensive summary of the results of considerable geological, survey and beneficiation work which has been carried out at four mines. The mined deposits have been formed in Burra Group schists and gneisses that constitute the...

The Dudley pegmatite, located 10.5 km south-east of Penneshaw, was worked during the 1890s and early 1900s for gem tourmaline, ceramic-grade feldspar and silica, and kaolin for brickmaking. The pegmatite outcrop strikes in a north-easterly direction...

South Australia has been a traditional source of non metallic minerals. Those minerals currently being mined that offer scope for expansion is – Barite – In pigments, drilling muds, the manufacture of barium chemicals and for medical purposes...

Aim was to estimate effects of modifications on the cost of producing aluminium sulphate solution from Birdwood clay for the treatment of domestic water supplies.

The Engineering and: Water Supply Department has let a contract to Adelaide and Wallaroo Fertilizers limited for the supply of an estimated 8,000 to 25,000'tonnes per annum of aluminium sulphate solution OW.5% A1203) to be used% ais'a coagulant for...

Kaolin deposits at Birdwood, 48 km NE of Adelaide, are a commercial source of well-crystallized kaolinite formed in medium-grade metamorphic rocks equated with Saddleworth Formation of Adelaidean age. The kaolin appears to have formed by weathering...

The kaolin deposits located south-west of Poochera on northern Eyre Peninsula have formed by deep weathering of early to mid-Proterozoic crystalline basement rocks, which are now blanketed by late Tertiary to Quaternary terrestrial sediments. During...

The Poona Copper Mine on northern Yorke Peninsula, South Australia, was worked from 1988-92 on an extension of the original Poona lode, a narrow, shear-hosted copper sulphide vein deposit in Moonta Porphyry of Mesoproterozoic age. The orebody is...

This report summarises the main consumers, reserves, production and probable life of current mines and identifies potential alternative sources. Shale reserves in the currently worked pits are sufficient for 50 years, white plastic clay at Golden...

Established producers have taken advantage of export opportunities for gypsum, salt and dolomite. New developments include a graphite processing plant at the former Uley Graphite Mine and trial mining of micaceous iron oxide for pigments. Proposals...
