Concentrating means to remove the waste rock from the lead. To begin, the ore must be crushed into very small pieces. The ore is ground at the mill, leaving it in particles with diameters of 0.1 millimeter or less.The rock is then crushed by powerful machinery. Metal is extracted from the crushed ore by one of two major methods smelting or electrolysis. Smelting uses heat to separate the valuable metal from the rest of the ore. Smelting usually requires a reduction agent, or another chemical, to separate metal from its ore. In the earliest smelters, .Once the ore has been mined and crushed to a powder, it is placed in a furnace to be fused along with lead andor litharge PbO, charcoal, and fluxes.
