methods of minning lead and zinc
Underground Mining Methods of Zinc Ore
The methods of mining followed in this field, and even in individual mines, are varied in accordance with the character of the ore The general practice of the field is to sink vertical shafts, generally on the footwall side, free from the liability of disturbance from settlement due to stopingMining is the method of tacking materials from the earth to get valuable metal ores like copper, zinc, and lead, which are known as target minerals in mining terms Metal ores like copper, zinc and lead are minute quantities contrasted to the whole composition of the earthSulfide Mining, Mining Methods, Techniques, Copper, Zinc

Zinc and Lead
Zinc (Zn) is a bluishwhite lustrous metal that is brittle at room temperature, but malleable when heated It has a low melting point (4195°C) and a moderately high specific gravity (713) Lead (Pb) is a soft, ductile, malleable, bluishwhite metal with a low melting point (3274°C) and a high specific gravity (113) Zinc and lead minerals often occur together because, as elements, theyZinc is characterised as a bluishwhite, lustrous, diamagnetic metal, hard and brittle at most temperatures Zinc is the 24th most abundant element in Earth's crust and is usually found in association with other base metals such as copper and lead in ores Zinc prefers to bond with sulphides because of its low affinity (liking) for oxidesZinc Ore Mineral Deposits in Nigeria with their Locations
