Lead Mining ‐ Methods used by Alastair Laws There were five main methods of mining lead Digging – by following the vein along the surface and digging it out, much in the way of open cast coal mining. Firing – where a roaring fire was built up against the rocks, allowed to cool and then doused

How lead is made - material, used, processing, product ...

BackgroundThe Manufacturing ProcessByproducts/WasteThe FutureLead is a dense, soft, low-melting metal. It is an important component of batteries, and about 75% of the world's lead production is consumed by the battery industry. Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against X-rays. Lead resists corrosion by water, so it has long been used in the plumbing industry. It is also added to paints, and it makes a long-lastin查看有关madehow的更多信息

Mining - Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Mineral processing - Wikipedia
