Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by …

Refining is the process by which players can turn materials gained from Gathering into usable items for Crafting. To refine gathered resources, the player must travel to refining buildings that can be located in Faction Cities or built on Islands. The refining process costs silver (except when refining tier 2 resources) and the player can …

7.1.6 METAL REFINING OF ORES. In the metal refining of ores, the metal is solubilized in an aqueous solution. The optical control of metal refining requires quick, accurate analysis of the major chemical species present in solution. Raman spectroscopy and resonance Raman are used to identify the amine complexes of Co, Ni, and Cu species, as ...
