Most of these companies are small operations engaged in the physical tasks involved in mining, as well as in planning, development, and exploration. Some companies specialize in preparing mine shafts and tunnels, while others offered test boring services

Mining techniques can be divided into two common excavation types: surface mining (above ground) and subsurface (underground) mining. sometimes subsurface mining is also called deep mining like in my text book p.s i am in 8th grade
They aren't considered to be ores because ores are partly mineral and partly metal. The metal deposits are purely metal.
Prospecting and exploration for uranium continues in Gabon. It has been ongoing for some years, but though extensive deposits have been located, the extent of these deposits and the concentration of uranium in the ore make economic recovery questionable. At least four large mining consortiums are still in the hunt, however. As the market for uranium evolves, the companies continuously evaluate the profitability of a mining venture for this heavy metal in Gabon.
Geographically speaking, the state of Nevada has the most companies engaged in mining services.

Metal-bearing rocks sought after in mining are typically called ore deposits. These deposits contain high enough concentrations of valuable metals such as copper, gold, silver, or iron to be economically viable for extraction. Mining companies prospect for ore deposits to extract and process the valuable metals.
Extracting a metal oxide from the ground
You have to mine the metal ore (an ore is a rock containing a metal compound) before you can extract the metal from it.
Gold is recovered by three basic mining methods: placer mining of alluvial deposits, lode or vein mining, and recovery as a by-product of base-metal mining.
