Salt Mining | HowStuffWorks

In solution mining, wells are erected over salt beds or domes (deposits of salt forced up out of the earth by tectonic pressure) and water is injected to dissolve the salt. Then the salt solution, or brine, is pumped out and taken to a plant for evaporation. At the plant, the brine is treated to remove minerals and pumped into vacuum pans, sealed containers in which the brine is boiled and ...

What are the main methods of mining? | American ...

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

11.19.1 Sand And Gravel Processing

Mining methods depend primarily on the degree of cementation of the rock. In some deposits, blasting is required to loosen the material prior to processing. The material may undergo primary crushing at the mine site before being transported to the processing plant. Figure 11.19.1-2 is a flow diagram for industrial sand and gravel processing.

Tunnelling: Mechanics, methods, and mistakes

For centuries, tunnels in rock were driven by building fires against the rock faces, which would cause expansion and spalling, often accelerated by dousing the hot rock with water, then picking the fractured rock away with picks and wedges (Wahlstrom, 1973). Egyptian and Roman mines were worked to depths of approximately 200 meters.
