How to Process Oxidized LeadZinc Ore by Flotation

The problem of treating oxidized leadzinc ores for the production of highgrade lead zinc concentrates is a complex problem due to the nature of the ores and to the soft sliming characteristics of the lead and zinc minerals. The ore for treatment is a leadzinc carbonate ore in a mixed siliceouslime carbonate gangue.

Lead Statistics and Information USGS

Lead is a very corrosionresistant, dense, ductile, and malleable bluegray metal that has been used for at least 5,000 years. Early uses of lead included building materials, pigments for glazing ceramics, and pipes for transporting water. The castles and hedrals of Europe contain considerable quantities of lead in decorative fixtures, roofs, pipes, and windows.

MINING AND PROCESSING : Lead is known to naturally occur in free form in nature, but is generally obtained from the ores galena(PbS), anglesite (PbSO 4), cerussite (PbCO 3) and minum (Pb 3 O 4). It is never considered to be a rare element even though it makes up only about 0.0013% of the earth''s crust since it is easily mined and refined.

Introduction to Mineral Processing

The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated. The tailing from the lead flotation circuit is the feed to the zinc circuit.

Lead: smelting, producing and classifiionMetalpedia

A major and primary Lead mineral is galena (PbS) which comprises of 86.6% of lead. In order to smelt this mineral, a blast furnace is needed to be used. A blast furnace is an enormous oven which is used to accomplish the smelting processes. The process in which galena is smelted requires two important chemical reactions to occur within the furnace.
