Galena (PbS) and sphalerite (ZnS) are the main sources of lead and zinc and usually associated in sulfide deposits. Because of the similar surface properties of these two minerals, their flotation separation is a persistent topic of interest in mineral processing [1].Xanthate is the most commonly used collector for sulfide mineral flotation, but its poor …

Selective depression of galena in the galena and …
The separation of galena (PbS) from chalcopyrite (CuFeS 2) requires strong oxidants for the depression of PbS, due to the excellent hydrophobicity of PbS.In this work, an advanced oxidation process, i.e., S 2 O 8 2− /Fe 2+ treatment, was employed to selectively depress PbS. The parameters of the S 2 O 8 2− /Fe 2+ process were determined via flotation …

One-step extracting lead from galena (PbS) by a vacuum …
Lead sulfide (PbS) is the main component of galena. The traditional method used to prepare metal lead from galena is disadvantaged by high energy consumption and severe pollution. In this paper, an eco-friendly yet simple process is proposed to prepare high-purity metal lead directly from lead sulfide.

The electrons of different types of atoms have different degrees of freedom to move around. With some types of materials, such as metals, the outermost electrons in the atoms are so loosely bound that they chaotically move in the space between the atoms of that material by nothing more than the influence of room-temperature heat energy.
