The selection of the adequate mining method is the cornerstone for mine planning and design. This selection depends on geological, geotechnical, economical, and environmental parameters. This paper's main purpose is to select the most appropriate mining method for the south body of Boukhadra underground mine (NE Algeria). To do so, a new study is needed …

The selection of the adequate mining method is the cornerstone for mine planning and design. This selection depends on geological, geotechnical, economical, and environmental parameters.

Underground mining is commonly used for the extraction of coal, iron ore, oil, and diamonds. A significant type of underground mining technique includes room and pillar mining. ... In-situ mining, also known as in-situ leaching or solution mining, is a method used to recover valuable minerals from ores. It consists of injecting chemicals into ...

The development of mining technology and sustainable methods will be pivotal in creating a steady and conscientious supply of iron ore to be able to cover the world's demands. By becoming aware of the iron ore mining process and its importance, we will be able to take into consideration the important role this fundamental product has in ...

Exploitation of existing iron ore deposit is the easier part of the mining operations. The harder part is to find new ore deposits and to define their extent and the iron content (grade). Exploration is the process by which the accumulations of …

Besides copper, gold, and iron ore, other minerals such as uranium, gravel, and dimension stone are also commonly extracted through this method. This mining method is considered different from quarrying in the sense that it selectively extracts ore rather than an aggregate or a dimensional stone product. The scale of open pit mining operations ...

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 …

Iron ore is essential in steel making; however, high-grade ores have diminished, making low-grade ores inevitable. These low-grade iron ores need further beneficiation to upgrade the iron content. Currently, traditional physical and chemical methods are utilized and are not environmentally friendly. Bio-beneficiation techniques have emerged as a sustainable …
