The Ron Phibun tin-mining district of Thailand is an exception (Williams et al. 1996). In this area arsenopyrite oxidation products were suggested to have formed in the alluvial placer gravels during the mining phase. Following cessation of mining activity and pumping groundwater rebound caused dissolution of the oxidation products.
Placer mining - Wikipedia
Placer mining / ˈplæsər / is the mining of stream bed ( alluvial) deposits for minerals. This may be done by open-pit (also called open-cast mining) or by various surface excavating equipment or tunneling equipment. Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones both of which are often found in alluvial deposits—deposits of sand and gravel in modern or ancient stream beds or occasionally glacial deposits.
Wobbler Feeders | McLanahan
The Wobbler Feeder is used in aggregate and mining applications to sort the run-of-mine material before the primary crusher. This scalping of the feed reduces unnecessary wear on the primary crusher. Since scalping the feed reduces the amount of material going into the primary crusher it also reduces the required size and capacity of the ...
