Continuing intensive exploration for economic sedimentary uranium deposits within buried Tertiary palaeochannel sediments in the Yarramba Homestead area, 50 km north-west of Cockburn, which had been invigorated by the recent discovery of strongly...

In-situ leaching of a uranium orebody can only be successful if the deposit meets a number of essential criteria. These criteria are: 1. The ore occurs in a generally porous and permeable horizontal bed underlain and overlain by impermeable strata;...

Ongoing copper exploration in the Mount Gunson area was directed primarily at locating economic stratiform mineralisation in the Tapley Hill Formation, which overlies Pandurra Formation and the associated Cattlegrid orebody. New work comprised...

Work carried out at Amdel and at the Colorado School of Mines' Research Institute has indicated that both a two solvent system (EHPA and TBP or DBBP) and a three solvent system (EHPA, DBBP and Alamine 336) of cationic exchangers are satisfactory for...

The ore consists of clay, limonite pyrolusite and psilomelane, thoroughly mixed and carried quartz, barytes and gypsum crystallised in cavities. The average grade is 24 per cent manganese. 2. Beneficiation by gravity methods, by flotation or magnetic...

Copper extraction in percolation leaching was relatively slow because of the low porosity of the large rocks in the as-ripped ore. To obtain reasonable extraction rates, size reduction will be required. Agitation leaching of ground ore gave copper...

A research project to determine the leaching behaviour of oxidised copper ores at laboratory scale was undertaken by Amdel at the request of the South Australian Department of Mines. The trials took place using sulphuric acid lixiviant acting on the...

A collection of operational and technical reports relating to an experimental project of in-situ acid leaching of remnant copper sulphide ore at the historic Mutooroo mines, which are situated south of Cockburn in the Olary - Broken Hill district....

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

An area centred ~90 km north-east of Streaky Bay was taken under licence to explore for possible economic underground concentrations of dissolved potassium, lithium, boron and magnesium which may have become ponded within stagnant groundwater lenses...

During the 2009-2010 reporting year, Great Southern Kaolin Pty Ltd (GSK)'s activities comprised: - commissioning the pilot plant at the fabrication site in Kingaroy, Qld, in May-June 2010, and processing about 2 t of kaolinised granite through it to...

The main problem, leading to poor recoveries of copper from the Kadina - Wallaroo tailings dump materials being put through the Kadina copper concentrator, is an increasing amount of oxidized sulphide minerals in the treated tailings. Testing by...

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...
