Gold ore treatment at Beaconsfield mine. Gold ore treatment plant was commissioned in 1998 and the first gold bar was poured in September 1999. The treatment plant will now be used for the Lefroy Tailings Retreatment Project. Around 150,000t of Lefroy tailings were treated at the Beaconsfield process plant. The plant will now be used for processing ore from Stormont mine.
1.1 PHASES OF A MINING PROJECT - elaw.org
Placer mining is used when the metal of interest is associated with sediment in a stream bed or floodplain. Bulldozers, dredges, or hydraulic jets of water (a process called ‘hydraulic mining’) are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains.
