BACKGROUND REPORT PRIMARY ZINC SMELTING Prepared

Zinc ores typically contain three to eleven percent zinc, along with cadmium, copper, lead, silver, and iron. Beneficiation, or the concentration of the zinc in the recovered ore, is accomplished at or near the mine by crushing, grinding, and flotation. Once concentrated, the zinc ore is transferred to smelters for the production of zinc or

WILLEMITE (Zinc Silicate) Amethyst Galleries

Willemite is a somewhat rare zinc mineral, but it was found in such great abundance at Franklin New Jersey that it instantly became an important ore of zinc. The deposit at Franklin, New Jersey is truly unique. Not only is willemite found there but other rare minerals are also found there, and some in amazingly large quantities.

Zinc

Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity
