##tihuan2##Native Lead is a very rare mineral, with few noteworthy localities. Perhaps the best collectors specimens come from Langban, Sweden. The Harstigen Mine in Varmland, Sweden has also produced a limited amount of Lead, and it has also recently been found in the Garpenberg Noora Mine, also in Varmland, as thin sheets.

##tihuan2##This culminates into low grade, fine grain size, complex ore mineralogy, and poor liberation, thus, causing the beneficiation of lead-zinc ore a challenging task. This paper summarizes the classification of ore deposits and different beneficiation techniques that are currently employed for the treatment of lead-zinc ore.

##tihuan2##Mining is entirely by underground methods and occurs at depths as great as 1,400 feet. Ores are blasted, crushed, transported to the surface, crushed further and run through flotation cells to separate the lead ore from the dolomite or limestone and other ore and non-ore minerals. Ores are then shipped to be smelted to generate lead metal.
