Lead solubility in FeO x-CaO-SiO 2 slags at iron

Experiments have been carried out to determine the equilibria between FeO x-CaO-SiO 2 slag and lead metal in iron crucibles at temperatures ranging from 1473 to 1573 K. It has been found that the highest lead solubilities are observed in the silica-saturated iron silie slags, while the lowest solubilities are observed in the CaO-saturated calcium ferrite slags.

Challenges of digitalizing the circular economy

The metal wheel shows that lead, as well as other base metals such as copper, offer metallurgical platforms to recover many elements in the CE, acting as a source of technology elements from ores and also acting as powerful high temperature liquid metal solvents of minor technology elements during smelting, which are released during refining (Reuter et al., 2015a).

Lead - Wikipedia

2019-4-20 · Lead (/ˈlɛd/) is a chemical element with syol Pb (from the Latin pluum) and atomic nuer 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air
