  • Zinc production environmental impact

    Zinc occurs only in a combined state. The dominant zinc ores found in the earth's crust is zinc blende (zinc sulphide or spharelite) ZnS, calamine ZnCO3 and Zincite, Zno. Zinc is commonly found in mineral deposits along with other base metals, such as copper and lead. Zinc deposits are broadly classified on the basis of how they are formed.

  • What Does Chelated Zinc Do?

    Jan 14, 2019Zinc is an essential mineral needed by your body in relatively small amounts, 20 milligrams or less per day, depending on your body size. Elemental zinc is very poorly absorbed in your gut so in supplemental form, it's often attached to a chelating agent, which is a compound that binds or grabs onto it and facilitates absorption.
