Lead and Zinc Energy

2013-11-8  Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. Primary lead was processed at smelter-refineries in Missouri and in Montana.1 Zinc Ore Zinc is a shiny, bluish-white metal. Zinc metal is never found pure in

PRIMARY PHASES AND NATURAL WEATHERING OF OLD

A substantial amount of zinc, initially dissolved in the silicate melt, is held by zinc-rich end-members of the spinel (gahnite, up to 19.9 wt% ZnO) and silicates (e.g., hardystonite, up to 10.5 wt% ZnO). Lead, in contrast, behaves as an “incompatible element” and is likely to be concentrated in the residual matrix glass.

lead, zinc, or both is fed, in some cases after sin-tering, into a primary smelter. Lead concentra-tions can be 50–70%, and the sulfur content of sulfidic ores is in the range of 15–20%. Zinc con-centration is in the range of 40–60%, with sulfur content in sulfidic ores in the range of 26–34%. Ores with a mixture of lead and zinc

Interaction of lead and zinc in cultured astroglia

Astroglia take up lead (Pb)in vivo andin vitro. In view of the fact that zinc affects both tissue deposition of Pb and clinical signs of Pb intoxication, the present study was carried out to test the effects of various Zn levels on lead toxicity in astroglia. Primary cultures of astroglia from 1- to 3-day-old neonatal rats were divided into three groups and cultured in Waymouth's 752/1
