2020 Mining Facts

Auger mining: Form of underground mining that uses an auger (rotary drill) to penetrate, break and transport drilled material onto a waiting conveyor belt. Usually employed to recover remaining material in deep overburden areas that cannot be reached economically by further contour or area mining. Base metals: Any of the non-precious metals.

How Coal Works

2021-2-23Two dominant methods account for the vast majority of underground coal mining: "room and pillar" and "longwall" mining.. In room and pillar mining, seams of coal are partially mined, leaving large pillars of coal intact to support the overlying layers of rock. When finished, miners practice "retreat" mining, extracting as much coal as possible from the remaining pillars

pH and alkalinity

Water quality and pH are often mentioned in the same sentence. The pH is a very important factor, because certain chemical processes can only take place when water has a certain pH. For instance, chlorine reactions only take place when the pH has a value of between 6,5 and 8. The pH is an indication for the acidity of a substance.

How is uranium made into nuclear fuel

The mining of uranium . Uranium is found in small amounts in most rocks, and even in seawater. Uranium mines operate in many countries, but more than 85% of uranium is produced in six countries: Kazakhstan, Canada, Australia, Namibia, Niger, and Russia. Historically, conventional mines (e.g. open pit or underground) were the main source of uranium.

Metal Profile: Iron Properties and Characteristics

2020-1-12History . Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores.   The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000

How is gold mined?

Byproduct mining is related to hard rock mining in that open pit or underground mining tunnels are used. In byproduct mining, gold is a secondary find. The main purpose of the mining operation is the recovery of Copper, sand, gravel or other products but significant quantities of Gold exist to make byproduct mining a profitable venture.

WHERE IS IRON ORE MINED?

2021-1-21Iron ore can be found all over the world, in the form of rocks and other minerals. To be economically viable for mining, iron ore must contain at least 20% iron. Magnetite ore has the highest proportion of iron, at 65%. Haematite ore also has a high content of iron at 60%. All iron ore contains ferric oxide and it is from this that iron
