In October 1975, Mount Gunson mine operator Pacminex determined that the composition of mineable copper sulphide ore potentially obtainable from the undeveloped MG14 area would very likely be more difficult to process than existing Cattlegrid mine...

EXPLORATION: Systematic bulk testing of costean samples taken along exposed alluvial channels, by treatment in a wet jig plant. RESULTS: Economic to sub-economic gold values were confirmed as remaining in Brady's, Strawbridge and Deep Gully alluvial...

An agglomeration of exploration licences which partly surrounds the Challenger gold deposit at distances of between 35 and 80 km is being explored for similar type economic lode gold mineralisation that may exist in buried Archaean bedrock relatively...

Reports describe the planning and conduct of an experimental heap leach of 3000 tonnes of oxidised copper ore which took place at Mount Gunson. The mine operator's intent in proving this metal extraction concept is to successfully heap leach, with...

TARGET: Ongoing evaluation of the Honeymoon deposit. EXPLORATION: Pilot wellfield drilling (48 holes) on a 60 m by 30 m grid over the eastern half of the deposit, hydrological investigations, metallurgical testing, and in-situ push-pull leaching...

This report covers laboratory experiments designed to determine the optimum addition of Reagent S.3000 during the thickening operation of pulp leached from Radium Hill concentrates. Use of this reagent as a 1% solution up to 0.6 pounds per short ton...

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...

Potential of fluidized bed entrained state heater system is limited. Process not economic at current titanium prices and technical difficulties remain.

Tests included flotation tests with salt water and wet magnetic separation on newe 10 ton bulk sample from Brown shaft.

Experiments carried out on ion exchange adsorption of uranium, from sulphuric acid leach liquors of Radium Hill ores, have demonstrated that ferric iron in the liquor has a detrimental effect on adsorption efficiency and on the quality of the product.

Various methods of treating oxidised copper ore remaining in the abandoned open cut mine and surrounding waste dumps at Burra have been investigated using more representative, recently gathered samples, and the results are here summarised. Ore...

With the increasing interest shown in smaller scale, copper operations in South Australia, a further investigation into the possibilities of treating the remnant ore from the old Kapunda Mines was considered warranted. The deposit is estimated to...

In South Australia, at the present time, mining companies are interested in copper mining and ore beneficiation. To be in a position to provide data which would make it possible, at any time, to assess the feasibility of establishing a copper smelter...

In October 1970 Amdel proposed to the South Australian Government Department of Mines that an allocation be transferred from Project 1/1/115; "Evaluation of Kapunda Ore"; to a new project in which the economics of various processes for...

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...

Analytical and mineralogical work carried out on core from 4 drill holes show deposit is suitable for in situ leaching. Alkaline leaching using ammonium carbonate is preferred.

As part of a planned project to rehabilitate the disused, government-owned Mount Torrens gold treatment plant, expert research was commissioned by SADME into selection of a suitable extraction process to remove remnant gold credits from accumulated...
