Vein Mineral Deposits - Mineral Processing & Metallurgy


Vein Mineral Deposits includes a considerable variety of ore deposits formed under various conditions by the concentration of the ore from the molten rock in process of cooling, and its subsequent deposition in fissures and joints, crevices, and pores; or the accompanying solvents make room for the ore by dissolving the rock and carrying it away.

Structures of Mineral Deposits


Mineral deposits formed as a consequence of sedimentary processes. Structural deformation may alter the form and attitude of some of these deposits. Lenticular masses, veins, lodes and zones of disseminated mineralization result from metamorphic processes. Recognition of the environment and existence of potentially economic mineral deposits may be based upon a variety of geological criteria:
