  • The Geology of Rare Earth Elements

    Rare earth elements-bearing minerals, once separated, contain as many as 14 individual rare earth elements (lanthanides and yttrium) that must be further separated and refined. The complexity of extracting and refining rare earth elements is illustrated by a metallurgical flow sheet for the Mountain Pass mine in California (fig. 2).

    Different lasers extract ore at different speeds, and sometimes you will need special lasers to extract certain ores. To begin mining, get in range [usually within 10km for starting lasers], target an asteroid, and then activate your laser. It will then start to extract the ore from the asteroid, putting it in your cargo hold.

    However, if the ore is ground to -200 mesh, most times, a few specs of gold can be visibly seen under microscopic examination. Based upon numerous case studies, it appears that gold particles in pyrite are generally fine, ranging from 75 microns down to 2 or 3 microns. The incidence of fine gold's quantity also appears to be related to the gold ...

  • Heap leaching - Wikipedia

    Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...

    In general, the rarer the ore, the higher its volume per unit (e.g. one unit of Veldspar has a volume of 0.1 m 3, whereas one unit of Arkonor has a volume of 16 m 3). Since mining lasers mine a given volume of ore per minute, it takes longer to mine the rarer ore types. Additionally, each ore reprocesses into a different set of minerals.
