Which of the following terms describes a rock body where the concentration of a mineral is high enough that it is profitable to mine? resource. mineral deposit ...
The results from the laboratory scale study indicated selective pre-concentrations of the REE minerals and iron oxides in the HM feed (unclassified feed samples) while rejecting mostly mineral silicates such as quartz, muscovite and feldspar minerals. The concentration technique also obtained monazite, bastnasite as well as …

1.2 Ores and Minerals. Ore is a term used to describe an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined and extracted. Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or …
a mineral, rock or organic material that can be used as jewelry or an ornament when it is cut and polished. lode. a mineral deposit within a rock formation. ore. a natural material whose concentration of economically valuable minerals is high enough for the material to be mined profitably. placer deposit.
Mineral deposits can form through a variety of processes, some of which include: 1. Magmatic processes: Some mineral deposits are … See more
A placer ore body is a concentration of eroded particles of valuable minerals in an alluvial or eluvial deposit of sand or gravel. The ore minerals in such deposits crystallize initially within the crust, in magmas or metamorphic rocks, or from hydrothermal fluids. ... and monazite (a phosphate of Th and the rare earth elements). The ...
