• 16 Energy and Mineral Resources – An Introduction to Geology

    All ore minerals are mixed with less desirable components called gangue. The process of physically separating gangue minerals from ore bearing minerals is call concentrating. Separating a desired element from a host mineral by chemical means (including heating in the presence of other minerals.

  • 6 Stages of the Mining Process | BOSS Magazine

     · This stage of the mining process requires establishing a path to the mineral deposit. That path, however, requires more than excavation. In order to even begin work, mining rights must be acquired, access roads must be constructed to help workers navigate the site, and a power source must be established. Production. Once these elements are obtained, the physical mining process—or, the .

    Their logs are highly detailed and this type of logging is a must for new logging areas without well defined ore zones. It also allows for potential new ore zones to be identified more readily in the future. This method however is very time consuming. A grouper style logger will log two to five times the amount of core in the same time frame as the separator.
