Detailed explanation-1: -Sulphides are minerals with the S–2 anion, and they include galena (PbS), sphalerite (ZnS), chalcopyrite (CuFeS2), and molybdenite (MoS2), which are the most important ores of lead, zinc, copper, and molybdenum respectively.
Detailed explanation-2: -sulfide mineral, sulfide also spelled sulphide, any member of a group of compounds of sulfur with one or more metals. Most of the sulfides are simple structurally, exhibit high symmetry in their crystal forms, and have many of the properties of metals, including metallic lustre and electrical conductivity.
Detailed explanation-3: -galena, also called lead glance, a gray lead sulfide (PbS), the chief ore mineral of lead.
Detailed explanation-4: -Galena is the natural mineral form of lead sulfide (PbS).
