Pre-Columbian lead pollution from Native American galena processing and land use in the midcontinental United States. Geology, 2019; DOI: 10.1130/G46673.1 Cite This Page :

In this paper, an eco-friendly yet simple process is proposed to prepare high-purity metal lead directly from lead sulfide. According to thermodynamic calculation, lead sulfide can be decomposed into metal lead under vacuum. The pathway to decomposition is based on the reaction of 2PbS (s) = 2 Pb (l) + S 2 (g).

In Nigeria, lead ore is primarily found in association with galena, a lead sulfide mineral. This unassuming mineral carries immense economic potential, contributing to Nigeria's mining heritage. Key Features of Nigerian Lead Ore: Lead ore is a primary source of lead globally, and Nigeria boasts substantial deposits of this valuable mineral.

The gravity separation separator commonly used for beneficiation of galena is a jig machine. For the coarse-grained galena, we can use the AM30 jig machine, and the selected size of this jig machine can reach 30mm. For that fine-grained galena, we can use the 2LTC-6109/8T jig machine. This jig machine is aimed at 0-8mm fine minerals.

Galena is the natural mineral form of lead sulfide (PbS). The mineral occurs as fine to large crystals due to syntectonic remobilization at low temperature and move to a suitable location. The color is shining lead-gray and silvery (Fig. 1.39) with high specific gravity between 7.2 and 7.6 g/cm 3 containing 86.6% Pb in the purest form.
