This report reviews the available information on the region, and presents a preliminary appraisal of the data supplied by South-western Mining Co. Ltd. Current field and laboratory information has also been included. New geological and geochemical...

The problem of efficient washing was first approached with a view to providing excess wash, it being reasoned that as long as excess wash was available the maximum number of displacements through the filter could be attained dependant only on the...

The molten chloride process previously described has been modified to enable the production of electrolytic uranium metal powder directly from impure oxide. The grade of metal obtained is not sufficiently high for atomic energy purposes. High purity...

A novel process for the manufacture of pure uranium metal is described, in which impure uranium oxides are converted to chlorides in a molten salt bath by means of a graphite chlorination reaction. The melt is then purified and uranium metal recovered...

The operation of a planned industrial plant, designed to produce Portland cement and sulphuric acid from anhydrite, is described. Profitable operation of the process in South Australia, using gypsum as the principal raw material, is shown to be...

In an earlier report Wilmshurst (1963) proposed a novel method for extracting bromine from the residual liquor (bittern) resulting from the production of sodium chloride by solar evaporation of sea water. The bromine was to be released by chlorine,...

This report covers readings and observations made during the voyage to Japan of a cargo of concentrates from Peko Mines N.L.

This report gives preliminary details and estimated capital and operating costs for the planned possible treatment of kyanite-bearing ore in the Radium Hill mill. The estimated costs are based on the scale of treatment of ore required to produce 50...

The report includes a preliminary estimate of equipment sizes, capital and operating costs, together with a possible flowsheet of a treatment plant for treating slag at Copperfield Q'ld.

Includes activities of the Division since its inception; and records of pilot plant work relating to the chemical processing, for treatment, of Radium Hill uranium concentrates to produce high grade chemical salt; with photographs of plant...

Laboratory tests leading to installation of magnetic separation plant, and to heavy media plant, are decribed. Operations of plants are reviewed. Lab. tests of flotation are described. Operating costs of pilot plant are discussed.

Background: Enormous reserves of high grade polyzoal limestone exists in the South east of South Australia near Mount Gambier. The conventional methods of calcinations (vertical shaft kilns, rotary kilns and multi stage fluidized beds) are either...

Background: Australia currently imports about 430 000 tons of elemental sulphur per year, valued at about $12,000,000 in 1966. The sulphur is purchased from Canada, the USA and Mexico. The annual production of elemental sulphur in these three...

This appraisal of the Northern Adelaide Plains Groundwater Supply has been .carried out under the commission of the Director of Mines, South Australia. The appraisal is based on information compiled by the Department and re-produced in the appendices...

Background In 1965 the South Australian Government Department of Mines authorised Amdel to carry out a review of lead and copper smelting operations. This decision was undoubtedly prompted by the proving of considerable reserves of lead ore at...

Over the last few years, a problem has existed along Dawesley Creek due to the release of acid waters with a high concentration of iron and appreciable contents of other heavy metals from the mine area of Nairne Pyrites Limited at Brukunga. This...

This study reports on a project to establish a magnesium oxide derivatives business in South Australia, by exploiting a resource of sedimentary magnesite held by Commercial Minerals Ltd (a member of the Normandy Poseidon Group of companies). Aspects...

Ongoing exploration in the Kalkaroo joint venture (formerly called South Eagle - Yarramba) area, located 40-80 km north-east of Olary and 50-150 km west-northwest of Broken Hill, has continued to target stratabound/epithermal/hydrothermal Pb-Zn-Ag and...
