problems with mining sphalerite

Sphalerite AND Sulphides - Mineral Processing Metallurgy As sphalerite is such a common constituent of many types of ore, the present investigation was undertaken to determine what its relations are to the other minerals in the deposits, and also whether these are of any genetic significance. Sphalerite is obtained from underground mining. It is a zinc ore that is formed in veins, which are long layers of rocks and minerals that form underground. Found in sedimentary, igneous and metamorphic rock, sphalerite is mined in many different places around the world, such as Mexico, Australia, Italy, Spain, Germany and various places in the United States.
