Lead ore is a somewhat uncommon ore that yields lead and small amounts of silver.. Obtaining. Lead ore is less common than iron ore, but more common than gold ore.It occurs at relatively low levels in the world (layers 15-35). Lead ore veins are slightly smaller than iron ore veins, and may contain one or two blocks of silver ore as well. Similarly, silver ore …

Smelting involves heating the crushed ore in a furnace to a very high temperature – over 1000 degrees C. Heating of the ore to such a high temperature removes the sulphur component of the lead sulphide (galena), either transforming the lead sulphide to lead oxide or to the metal itself. Pure lead itself melts at a relatively low 327 degrees C ...

In this paper, the impact of mining and smelting of lead metal ores on environmental quality is described. Globally mines produce large amounts of waste because the ore is only a small fraction of the total volume of the mined material. In the metal industry, production of lead, causes the greatest degradation of the environment.

The present method for smelting lead sulfide concentrates to produce lead is a pyrometallurgical smelting method that requires temperatures as high as 1,400 °C. Such smelting methods result in high lead and sulfur dioxide emissions. These high-temperature smelting operations will be unable to meet proposed emission standards.
