method of mining lead and zinc

Lead and zinc mining GeoKansas

The lead was extracted from the mineral galena, and the zinc was extracted from the mineral sphalerite. In general, mining was done underground, using the room-and-pillar method, in which room-shaped areas were mined and large pillars of rock left in place for roof support.

Characterization of Zinc, Lead, and Cadmium in Mine Waste ...

We characterized the lability and bioaccessibility of Zn, Pb, and Cd in size-fractionated mine waste at the Tar Creek Superfund Site (Oklahoma) to assess the potential for metal transport, exposure, and subsequent bioavailability. Bulk mine waste samples contained elevated Zn (9100 ± 2500 ppm), Pb (650 ± 360 ppm), and Cd (42 ± 10 ppm), while particles with the greatest potential for wind ...

Zinc and Lead

Zinc (Zn) is a bluish-white lustrous metal that is brittle at room temperature, but malleable when heated. It has a low melting point (419.5°C) and a moderately high specific gravity (7.13). Lead (Pb) is a soft, ductile, malleable, bluish-white metal with a low melting point (327.4°C) and a high specific gravity (11.3). Zinc and lead minerals often occur together because, as elements, they ...
