Beginner's Guide to Strip Mining | An Underground Miner
23/08/2022 10:21. Strip mining falls under the category of surface mining, an umbrella term that describes specialized mining techniques such as open pit mining, dredging, and more. These mining operations remove top layers of soil and rock, approaching mineral deposits through the surface rather than from underground.

9 Step Process for Discovering, Mining & Refining Gold
Step #3 – Drill Testing/Samples. Next, rock samples are taken through drill testing and analyzed. Geologists and mining engineers use these samples to determine if gold actually exists, the size of the deposit and the quality of gold in the ground beneath. This information is used to determine if enough gold exists under the surface to make ...

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 …

Oil and Gas Drilling
Unconventional O&G drilling then proceeds in two major phases: directional drilling and well stimulation. Directional Drilling. The process begins by drilling to the bottom of a fresh water aquifer. The drill is then retracted and pulls the loose rocks and sediment to the surface to be discarded (i.e., drilling muds).
