The square corners and edges, both of the whole crystals and of the broken pieces, are very characteristic. This is the common ore of lead. Zinc blende is often found mixed with galena. From the mixed minerals, both lead and zinc can be extracted; but .
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 crystallizes in the cubic crystal system often showing octedral forms. It is often associated with the minerals sphalerite, calcite and fluorite
A wide variety of lead sulfide options are available to you, such as industrial grade, agriculture grade, and medicine grade. There are 96 lead sulfide suppliers, mainly located in Asia. The top supplying countries or regions are China, India, which supply 94%, 1% of lead sulfide respectively.
With the exhausting of lead–zinc sulphide ores, the recovery of leadzinc oxide ores becomes more and more significant. Extensive work has been carried out at home and abroad on the treatment of lead and zinc oxide ores in reagent scheme, flotation flowsheets, and joint process. Sliming is one of the main reasons why the leadzinc oxides are difficult to recover.
