Chromium | Minerals Education Coalition

The mining method used for extracting chromite depends greatly on the characteristics of the deposit. These characteristics include whether it is stratiform or podiform, high grade or low grade, subsurface or near surface, or massive or disseminated. Because surface mining typically is less expensive than underground mining, it is preferred, but not always possible.

Nickel Mining, Nickel Mines, Nickel Mine, MINING AND PROCESSING : The mining methods differ with respect to the type of ore being mined. Since nickel is composed in two types of ores, both of them are mined differently. The sulfide ores are mined using underground mining methods though open-pit mining can also be done in early stages. The laterite ores are mined through applying earth-moving operation techniques. Usage of large Resolution Copper Mining Method - YouTube08.11.2012· Resolution Copper will use the panel caving mining method, a variation of block caving to break up the underground ore.

Chromite Beneficiation ProcessExperience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely freed until the ore is minus 16 mesh, it is obvious that the plus 16 mesh particles should be
