Brenda scott many raw materials are available at the surface of the earth. surface mining is a method of mining used to extract minerals and metals which are near the surface of the earth. there are three basic types of surface mining: open pit mining, strip mining, and quarry methods are much more economical than underground mining, yet they can have a more significant impact on.
Subsurface mining ; slide 2 ; what are mineral resources concentrations of naturally occurring solid, liquid, or gaseous material in or on the earths crust in a form and amount such that extracting and converting it into useful materials or items is currently or potentially profitable. there are metallic (ex. iron and tin ores) or nonmetallic.

Subsurface mining is the removal of deposits from the earth by drilling underneath layers of rock and dirt. these deposits are difficult to reach from the surface and require the drilling of vertical or horizontal shafts for access. solid subsurface resources are often blasted out of rock with explosives.
Mining is the extraction of valuable minerals or other geological materials from the earth. the geological survey agency of nigeria and the ministry of mines and steel development have reported the occurrence of more than 34 minerals in over 450 locations spread across the entire country, which are in various stages of development.
Minerals:gold, columbite, wolframite, tantalite, bitumen, iron ore and uraniume independence: 1 october 1960 area: 923,768 km2 mining fact: despite massive mineral wealth, the nigerian mining industry is vastly underdeveloped and only accounts for 0.3 of the countrys gdp – and this due to oil resources. the underdevelopment is resulting in nigeria having to import processed minerals.
Mining and (3) insitu extraction (see figure 2). the depth of bitumen below the surface determines which extraction type is possible. both insitu and largescale surface mining operations are most nigerias bitumen, also known as oil sands, has not yet been exploited, but is a potential source of future revenue for nigeria.
