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.

About 70% of Kangaroo Island soils are acidic and continued cultivation will cause increasing acidity. The best treatment is application of lime sand from deposits of Holocene Semaphore Sand along the southern coast. Material tested has high calcium...

History of exploration for Mississippi Valley type lead zinc in Cambrian limestone in the Flinders Ranges and of SADME involvement in exploration of Flinders Ranges National Park for BHP (EL 1080). The 1983-85 SADME investigations located 8...

The abandoned Brukunga pyrite mine is a source of acid drainage which pollutes nearby creeks. 6 holes (6627-WW 7454 to 7459) totalling 123 metres were drilled in the quarry benches to investigate acid drainage which is produced in 2 ways : 1....

A total of 28 landfill sites in the metropolitan area have been investigated for risk of groundwater pollution by leachate. All are municipal waste disposal areas, accepting mainly domestic garbage and hard fill. The investigation was carried out...
