    Ores Containing Cobalt Cobalt Institute

    In general common rock-forming minerals do not contain significant amounts of cobalt. However, it can be found in economic concentrations in olivine, spinel and chloride in lateritic and hydrothermal deposits (hydrothermal deposits occur where minerals are concentrated by the movement of hot fluids).

  • Veins and Hydrothermal Deposits Geology In

    Vein deposits of this nature are a type of hydrothermal deposit because the mineral species which compose the veins were precipitated by hot waters. However, sometimes the preexisting rock wall which contains the vein undergoes alteration. Portions of the host rock may either dissolve and be transported away or else react chemically with the circulating volatile fluids or the newly formed
