Mining Types: Hardrock Mining – This mining method requires digging into solid rock to find minerals in their ore form. The simplest form is utilizing picks and shovels, but rock drills and dynamite were often used as well. Shafts and tunnels might go straight down into the ground or advance horizontally into mountain faces.

25.2 Extracting ores | Mining of mineral resources | Siyavula

Rocks with large concentrations of minerals, are called ores. Mining depends on finding good quality ore, preferably within a small area. The next step is to get the rocks which contain the mineral out of the ground. Once the ore is on the surface, the process of getting the mineral you want out of the rock can start.

Methods of Gold Mining - Geology In

Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging. Gold panning is mostly a manual technique of separating gold from other materials.
