Lead and copper mineralisation occurs in rocks of Cambrian age in the Ediacara Mineral Field. Rich pockets of ore minerals of limited extent occur in the Transition beds and in the overlying carbonates, associated with breccias or turbidites....

Ore dressing investigations have shown that the branerite/absite fractions of Crocker Well ore can be concentrated with reasonable recovery by flotation (G.D. Sheridan, R.D.-80, 1958). Although the separation from the acid consuming mica minerals was...

Sediments in the area consist of blue dolomitic flaggy and laminated slates and grits, and are equated with the Sturtian Series of the Adelaide System. Copper lodes occur parallel to the beds, which dip between 50-70°W. During the period March to July...

The West Burra copper deposit, which lies in hilly country 3.5 miles west-southwest of Burra, was discovered in January 1913 and worked as a single 40-acre mining claim until that claim was cancelled on 18/2/1919. Information about the mine has been...

Field geological studies and site selection and feasibility for the proposed Middle River Dam have been completed, and a detailed report is in progress. The work has included detailed geological mapping at the dam site and at possible quarry sites,...

A geological and topographical survey has been carried out on a number of lenticular barytes bodies which cross-cut schists and dolomites. Open cut mining of the bodies has previously been abandoned. Underground mining to follow the lode appears to be...

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.

Between September 1963 and February 1964 a programme of diamond drilling and surface sampling was carried out at the abandoned Paull Consolidated mine and its environs, located approximately 18 miles north-east of Leigh Creek. Spectrographic analyses...

Irregular oxidised orebodies up to about 3 feet thick, containing copper carbonates, quartz, sphaerocobaltite (cobalt carbonate) and wad (hydrated manganese oxide), occupy both shear zones aligned parallel with bedding, and crush zones developed...

This report lists the results of acid leaching tests on Mary Kathleen ore. Attempts to control the silica concentration of the liquor have been made by leaching with and without additives and by processing the diluted leach liquors.

Ion exchange equilibrium and column tests have been conducted on Mary Kathleen leach liquors to examine the factors which influence retention of silica on Deacidite resins.

Two diamond drillholes, designed to test at depths from 70 to 100 feet the most favorable outcrops of cobalt-nickel mineralisation, failed to intersect extensions of the lode. Secondary erythrite mineralisation found along bedding seams, joints, and...

The use of dilute acid fluoride solution as a cyclic wash for the prevention of silica contamination in anion exchange resins is described. A cyclic wash employing 0.5 molar sulphuric acid and 0.05 molar ammonium bifluoride was found to be adequate in...

Copper carbonates are found irregularly dispersed within two types of quartz reef occurring in sheared Adelaide System quartzites and slates, 26 miles east south-east of Radium Hill and 4 miles south- southwest of Mutooroo Homestead. Mining there was...

Birdwood Kaolin Clay was subjected to the normal methods of acid leaching and acid salt roasting, but did not produce a sufficiently activated product for use as a decolourising agent.

Several clay samples were examined for possible activity in the decolourizing of mineral oils. Of those which responded to acid treatment, two were from local sources, and the others from remote areas beyond Port Augusta. The two local clays could...
