How is Opal Mined? | Opals Down Under
Opal is one of the few minerals which can be extracted economically by a miner working alone. The simplest form of mining, carried out in the early days of opal mining, is by shaft sinking with a pick and shovel. A shaft is sunk straight down until some promising "opal dirt" is discovered....
What are the main methods of mining? | American ...
Insitu mining, which is primarily used in mining uranium, involves dissolving the mineral resource in place then processing it at the surface without moving rock from the ground. The method used depends on the type of mineral resource that is mined, its location at or beneath the surface, and whether the resource is worth enough money to justify extracting it....
