Complexity: Even though the mineral processing volumes are huge, this should not be mistaken for a lack of complexity in comparison to manufacturing plants. A mineral processing circuit may consist of multiphase mass transfer, hydrometallurgical and thermal processes; these are often open to the elements and coupled to a variable and evolving feed.

Mining 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. Then they shovel the ore onto loaders and trucks, and haul it to a shaft.
