Lead and Zinc, 611 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do existUnderground mining (hard rock), Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubi Soft rock mining refers to excavation of softer minerals such as salt, coal ,(PDF) Surface Mine Design, The method of mining is unique for each different size and each shape of the ore body Mineral deposits differ in the shape and orientation of an orebody, the strength of theExtracting Lead Materials from Ore, Extracting Lead Materials from Ore Lead is a dense, soft, low-melting metal Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against X-raysLead resists corrosion by water, so it makes a long-lasting roofing material Only about half of the lead materials used today are produced from mining, the rest is obtained from ,GEOPHYSICAL METHODS IN EXPLORATION AND MINERAL ,, lows The gravity method also enables a prediction of the total anomalous mass (ore tonnage) responsible for an anomaly Gravity and magnetic (discussed below) methods detect only lateral contrasts in density or magnetization, respectively In contrast, electrical and seismic methods can detect vertical, as well as lateral, contrasts of resistivity.
