Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a bluesilvery appearance when oxidation is removed. It is the first element in group 12 of the periodic some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn 2+ and Mg 2+ ions are of ...
This causes most of the zinc ore to sink to the bottom and the lead ore to float to the top. The lead ore then gets skimmed off. (Additional chemicals, such as copper sulfate, allow the zinc ores to be skimmed off later in the process.) At this stage, the lead particles skimmed contain between 40 to 80% lead.

MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.
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
