Electrochemical desulfurization of galena-stibnite in,
20-08-2021· Therefore, the electrochemical desulfurization strategy is a promising technique to straightly produce Sb–Pb alloy from antimonial lead minerals without isolating Sb and Pb. Herein, liquid Sb 3 Pb 7 alloy was prepared by the direct electrochemical reduction of the mixture of stibnite and galena in eutectic NaCl–KCl melt at 730 °C.

Galena - Wikipedia
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver.. Galena is one of the most abundant and widely distributed sulfide minerals.It crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite
