10 000 tonnes of talc were produced since 1942. Talc and albite were formed by metasomatism within zones of intense shearing in metasediments of the Undalya Quartzite (Stonyfell Quartzite) and Woolshed Flat Shale. The lode comprises 52% talc, with...

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...

Grinding characteristics of talc from the 2 areas were compared. The project was terminated when it became apparent that Lyndoch talc was not as difficult to mill as was originally thought.

Background: Extensive deposits of talc exist in the Gumeracha-Lyndoch region of South Australia, located between 50-100 km north-east of Adelaide. Much of the talc rock contains a significant (5-30%) feldspar content. Project investigations have...

Old mines and prospects were located, sketch mapped and photographed. Ultra- violet lamp was used to search for scheelite in Mt McTaggart area and west of Mt Fitton. Scintillometer was used to search for radioactive minerals.

Object was to upgrade MgO to 30% and to improve colour of talc. Work included flotation tests and mineralogy. The low grade talc sample was contaminated with albite feldspar, but responded well to flotation to give concentrate containing 97.5% talc...

The Gumeracha deposits occur from Lobethal to Forreston and have formed by metasomatic replacement of metasediments of the Burra Group Undalya Quartzite and Woolshed Flate Shale. Steatite Hill deposit contains proved reserves of 156 000 tonnes of 65%...

Detailed mapping undertaken between 1982 and 1987 of 48 known jade outcrops located in the Cowell - Cleve area, and diamond drilling of 3 jade outcrops and 2 ornamental marble prospects, has identified many factors controlling nephrite formation. The...

Talc mines located near Mount Fitton produce 60% to 80% of the South Australian production of talc, of which two thirds is high grade material (suitable for pharmaceutical or paint manufacture). Over 40 known deposits occurring within an area of 60...

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...

This data package discusses mining and processing operations of the major non metallic and industrial mineral commodities in South Australia and is of interest to those in the industry and to manufacturers and suppliers of a range of machinery and...

Kapunda DC is underlain by folded Adelaidean and Cambrian metasediments which host important mineral deposits in the area. An estimated 15 million tonnes of ore averaging 1.2% copper remains near the Kapunda mine, with potential for further...

Geological mapping of an historically worked lamellar talc occurrence in the Tumby Bay area showed that snow white, finely flaky talc is present over a 2 km strike length within two beds of isoclinally folded schistose dolomitic limestone, but is of...

Talc occurs in the Mount Fitton area in a massive recrystallized dolomite of Proterozoic age. The larger talc deposits are concentrated on its margins. This massive dolomite cuts through bedding and formation boundaries, and available evidence...
