Beryl in this area is confined to pegmatite; particularly the coarsely zoned types, which are commonly quarried for feldspar. Feldspar quarries have in the past yielded much bi-product beryl, but at present beryl is not being produced owing to...

Review of methods, mainly from USA, and survey of patent literature.

Summary of deposits, products, methods of producing phosphorus and phosphoric acid and production costs. All reserves are low grade and unsuitable for super phosphate, but probably amenable to electrothermal reduction for phosphoric acid. Tests on...

During the period April 1st to July 14th 1964, the writer was privileged to visit overseas a number of important non-metallic mineral deposits including most of the world's major phosphate deposits. In the United States inspections were made of the...

Sample of phosphatic rock was tested by flotation with anionic and cationic reagents. No significant concentrations of apatite were obtained.

At least 90% of the phosphate was leached with either nitric, hydrochloric or sulphuric acids. Products unsuitable for the surface preparation of steel. The most promising outlet would be for upgrading the P2O5 content of super phosphate fertilizer.

The problem of the southern continuation of the Upper Proterozoic Adelaide Geosyncline is discussed. A transverse Cambrian trough and the related unconformity with the Precambrian is described, and its palaeogeographic significance outlined.

Since the days of early settlement in South Australia mineral production from Yorke Peninsula has made an important contribution to the wealth of the state. Firstly, with the discovery and mining of copper in the Moonta Wallaroo district early in...

The problem of the southern continuation of the Upper Proterozoic Adelaide Geosyncline is discussed. A transverse Cambrian trough and the related unconformity with the Precambrian is described, and its palaeogeographic significance outlined.

Visits have been made to most of the known South Australian phosphate rock deposits in order to make an appraisal of potential reserves. The deposits, with several exceptions, are associated with limestones of the Proterozoic and Cambrian systems....

Prospecting for asbestos and phosphate rock on the Kapunda sheet has been completed, and work begun on the Florieton sheet. Although 42 possible phosphate occurrences have been sampled, no economic deposit has been found. Small deposits of tremolite...

Mineral exploration on CHILDARA 1:250 000 geological map sheet was reviewed from SADME open file Envelopes, to complement an overview of regional prospectivity supported via the recent acquisition of high quality aeromagnetic data and a compilation by...

Exploration conduced over three semi-adjacent small licence areas located 50-75 km north-east, north and north-west of Marree targeted possible near-surface sedimentary uranium deposits in sandstone palaeochannels, and also sedimentary phosphate rock...

Two adjoining licence areas located ~50-70 km to the east and south-east of Blinman are being explored for possible economic buried willemite (zinc silicate), scholzite (zinc phosphate) and other base metal mineralisation associated with particular...

An area centred about 30 km south-east of Burra has been explored for possible buried economic Burra style copper mineralisation and for Mongolata Goldfield type alluvial and reef gold. The host metasedimentary unit to the Monster mine, the...

During the third year of exploration nominally ending on 1/7/2002 [and subsequent to the starting date of 5/3/2002 for the application of provisions of the Flinders Ranges Project's multi-tenement Amalgamation of Expenditure Agreement (AEA), whence...
