and gold. The most common lead-ore mineral is galena, or lead sulfide (PbS). Another ore mineral in which lead is found combined with sulfur is anglesite or lead sulfate (PbSO4). Cerussite (PbCO3) is a mineral that is a carbonate of lead. All three of these ores are found in the United States, which is one of the chief lead-mining countries.

The lead-mineralized samples are dominantly composed of galena up to a maximum concentration of 24%, and the partially oxidized galena is present in the range of 4.19–22.98% while quartz in these samples is up to 92% (Fig. 6). Mineralized grains in these samples are not in the form of dense accumulated grains but are distributed in the …
