Further to the design and cost estimate for a mobile gold treatment plant, the South Australian Government Department of Mines requested a design and cost estimate for a mobile crushing and sampling plant. The plant is to be capable of reducing 6-9...

Wet processed china clay rock is suitable as filler in paper manufacture and, with further reduction in grit content, for coating paper. Dry processed clay not bright enough for paper manufacture.

The 10 foot diameter Happy Valley Outlet Tunnel is a water supply tunnel designed to operate under a maximum head of about 70 feet. A 650 foot long section of the tunnel adjacent to its Outlet Portal has been driven through rock with a minimum...

A quarry site located near Lowbank on the River Murray, 7 miles east of Waikerie, has been geologically mapped and partly explored by drilling 14 vertical diamond holes with a total depth penetration of 702 feet. Marine sandy limestone and calcareous...

Whilst overseas during the period April to July, 1964, the writer visited, in addition to phosphate deposits, most of the major potash mines and a number of evaporated-salt, rock salt, brine and sulphur operations in North America, Europe and Israel,...

This report is complementary to an Amdel report in preparation entitled “Review of Lead Smelting Operations” and to a similar report on copper smelting operations which will be prepared at a later date. When concentrates are not smelted by the company...

A geological investigation of a deposit of Stonyfell Quartzite has been carried out. One subunit appears to be a suitable source of civil engineering construction aggregate. An area in which quarrying could be commenced is suggested.

Supplementary gravimeter traverses have been run over the strong Bungalow aeromagnetic anomaly to further define it. Earlier in the year a percussion drilling programme was carried out over the same area. In the light of both sets of results it is...

The raw gypsum contains 86.3 per cent. CaSO4.2H2O. This figure could not be improved by the conventional washing methods tried. The light brown colour of the raw material is not improved by washing. Colour determinations of the calcined fractions show...

Examination of gypsum material from the Streaky Bay area indicated that a gypsum concentrate assaying 95.1 per cent CaS04.2H20 could be obtained by simple washing and classification. Recovery at this grade was 82.2 per cent. Cyclone separation of the...

Roll crushing, drying and milling with air classification produces a high quality kaolin, quartz-free and of good colour.

Addition of various dyes, colouring agent and optical whitening agents did not visibly improve the colour of final cast plaster produced from Kangaroo Island gypsum.

Reserves of good quartzite at the existing quarry site are adequate to maintain the present production rate for some years. The overburden problem may be handled by cutting the upper bench higher up and working the quarry towards the west. An...

The groundwater licensing authorities in the States of South Australia and Victoria recognize that future development of the lands adjacent to the border will depend on the groundwater resource underlying those lands. In most areas there, shallow...

Processes suitable for use by small scale mining operations are discussed in detail. Covers methods of treatment for oxidized ores, sulphide ores and mixed sulphide oxide ores, marketing and economics.

At the Anna Coalfield, the November 1976 appraisal drilling by SADME of 2 rotary mud, partly cored vertical boreholes with a total penetration of 159.62 m (including 28.36 m of continuous ?NQ coring over the coal-bearing section) has confirmed the...

Shaking table that can be built by small mining operators has been designed to produce concentrates of heavy minerals. It is simple to build, has low power consumption and high throughput, and has been used successfully to treat ores of lead, tin,...
