How Is Sphalerite Mined? Career Trend

2019-9-4  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.
