There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. In-situ mining ...
Get PriceLead also commonly exists in ore containing other frequently mined materials, such as iron, copper, silver, and zinc. Thus, there are many different mining operations worldwide that could potentially be responsible for releasing lead into the environment.
Get PriceLead 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
Get PriceThis method is very selective and keeps dilution low, but requires many active stopes because ore is not removed from each mining area until completion – meaning longer lead times for ore to get to the process plant compared to cut and fill operations.
Get PriceMining the ore 1 The first step in retrieving lead-bearing ore is to mine it underground. Workers using heavy machinery drill the rock from deep tunnels with heavy machinery or blast it with dynamite, leaving the ore in pieces.

Get Price18/7/2020· Lead processing, preparation of the ore for use in various products. Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury). Its low melting point of 327 C (621 F), coupled with its easy castability and softness and malleability, make lead and lead alloys especially suitable for a wide range ...
