mineral processing metallurgy britannicamineralogical analysis a successful separation of a valuable mineral from its ore can be determined by heavyliquid testing, in which a singlesized fraction of a ground ore is suspended in a liquid of high specific gravity. particles of less density than the liquid remain afloat, while denser particles sink.

Advantages of ore dressing economics underground

mineral processing in all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. to do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur.

introduction to mining ci234;ncia vivapertain to the ore deposit being mined. mining is never properly done in isolation,nor is it an entity in itself. it is preceded by geologic investigations that locate the deposit and economic analyses that prove it nancially feasible. following extraction of the fuel, industrial mineral,or metallic ore,the runofmine material is generally

ore dilution amp; recovery in miningwhere it is imperative to prevent surface subsidence and resultant damage to surface improvements or to prevent an influx of surface or underground water, 20 to 40 percent of the ore in the deposit may have to be left as pillars. aside from ore left in pillars, high extraction is usually possible in open stopes, since the stope boundaries

environmental geology ch 13. mineral and rock as a an ore is a rock in which a valube or useful metal occurs. the more demand a certain rock has the more value it has thus it will be more valuble to be mined. the higher the concentration factor, the richer the ore, and the less of it needs to be mined to extract a given amount of the metal.
