Once it’s located within the earth, copper ore goes through eight stages before the consumer sees it in various products that affect every day life in the home and business. These eight stages include: 1. Mining 2. Grinding 3. Concentrating 4. Roasting 5. Smelting 6. Conversion 7. Anode Casting 8. Electro-Refining Documentation of the use of copper...

Advantages of strip miningThe advantages of strip mining mainly include the following six aspects: (1) The degree of mechanization is high. (2) High labor productivity. (3) The mining cost is low. (4) Fully recover the underground mining resources. (5) The infrastructure construction time is short. (6) Good worki
Advantage of subsurface miningCompared with underground mining, strip mining also has three major disadvantages: (1) The “three wastes” in the mining process are easy to destroy the environment (2) It is necessary to strip and discharge a large amount of waste rock, especially deep strip mines, and occupy a lot 在fuchenglhd上查看更多信息

Surface mining is best suited to extract minerals that are close to the surface of the earth. It is also usually a more cost-effective mining method compared to underground mining. Common minerals extracted using surface mining are some of the most mined including coal, iron and bauxite. Underground mining (or subsurface mining)احصل على السعر
2021-10-8 Subsurface mining is a process that involves the extraction of a metal or fossil fuel from the ground. It is the best and most well-known mining method. The subsurface mining process is helpful in the process of mining for gold, silver, lead, and even gems. Besides this, it is very much beneficial in the mining of coal, salt, and oil sands.احصل على السعر
