Surface Mining Sustainable Development & Environmental

Broadly speaking, there are two types of mines underground and surface. Considering the latter, surface mining includes: Large-scale opencast mines that are kilometres long and wide, and more than 300 metres deep. Mines such as these supply manganese, iron

Choose from the following list: gold, iron, coal, phosphate, manganese, diamond, chromium, copper and the platinum group metals (PGMs). Present your findings to the class in an oral and a poster.

Mining in Africa ProjectsIQ

Africa’s mineral industry is the largest in the world. Africa is a continent richly endowed with mineral reserves. It ranks first or second in quantity of world reserves of bauxite, cobalt, industrial diamond, phosphate rock, platinum-group metals (PGM), vermiculite, and zirconium. Gold mining remains Africa's main mining resource.

South Africa's most commonly mined minerals

South Africa’s mining reserves are estimated to be worth approximately R20 trillion. Let us look at which minerals are bringing in the most money in South Africa. Coal. Coal is an important resource because it fuels industrialisation. Coal is used to generate electricity, and is used in the production of steel and manufacturing of cement.

Strip mining is ideally applied where the surface of the ground and the ore body itself are relatively horizontal and not too deep under the surface, and a wide area is available to be mined in a series of strips. Typical examples of this type of mining are the larger tonnage coal mining operations in Mpumulanga. Favourable conditions are:

An Introduction To Surface Mining

There are five main types of surface mining that are used in various degrees and for different resources, including strip mining, open-pit mining, mountaintop removal, dredging, and high wall mining. Regardless of type, all surface mining procedures will remove waste material or overburden, above the desired resource.

Equipment Selection for Surface Mining: A Review

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.

Here are the Types of Underground Mining and Their

Depending on how these ores are extracted, mining methods can be categorized as ‘surface’ or ‘underground’ types. In surface mining, the rock barrier on top of the deposit is removed to access the ore. However, sometimes, such deposits occur too far below to access them from the surface.
