Lead ore is found from ores dug from ground mines. some form of lead is found in many minerals but the galena is a one of the most important product for getting lead. the galena has only lead and sulphar which is called pure galena.
Mineral processing techniques of lead ore. lead is extracted from ores dug from underground mines. lead is also found in conjunction with other metals such as silver and zinc. lead materials are mined as a by product of these other more valuable metals. extracting the lead materials from the ore is a tedious process. first the lead ore is

The majority of nucleated lead mines with ore works are of 18th to 20th century date earlier mining being normally by rake or hush and including scattered ore dressing features a 'hush' is a gully or ravine partly excavated by use of a controlled torrent of water to reveal or exploit a vein of mineral ore.
Underground mines. in underground mines the ore is extracted through a series of vertical shafts and ramps and horizontal drifts and adits see figure 2.4. extraction is more selective than in open pit mining and the ratio of waste rock to ore generated is much lower.
Underground mining. ... an underground mine is used. shafts are dug with tunnels branching out leading to the load deposits. ... after all of the processing of the ore and extraction of gold the ...
Usually kimberlite ore can be found in depths of at least 15 meters. when the diamond-rich depth is reached the raw material extracted from the ground is then transported to a special screening plant for further processing. there’s another form of alluvial mining called artisanal mining. in essence it is basically the same method employed ...
