Mining
Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore. Iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and …

Environmental Risks of Deep-sea Mining | SpringerLink
Deep-sea mining is a term used to describe the extraction of metals from the deep ocean. There are three common resource types—manganese, or polymetallic, nodules that occur in surface sediments in abyssal plain muds, mainly in the Pacific and Indian Oceans; cobalt crusts that occur as a surface crust on seamounts and rock …
Mining
Mining - Underground, Safety, Techniques: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of …
The Advantages of Open Pit Mining | Sciencing
Open pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas. Open pit mining is the preferred ...
