Lead is a dense, soft, low-melting metal. It is an important component of batteries, and about 75% of the world's lead production is consumed by the battery industry. Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against X-rays. Lead resists corrosion by water, so it has long been used in the plumbing industry. It is also added to paints, and it makes a long-lasting roofing material.
There are lots kinds of lead minerals, which have flotation differences between each other. The key

points in getting ideal technology index are the choice of effective inhibitors, pH regulators of slurry, and collectors.

Galena is the major lead sulfide. Galena in different place has differences in the types and amount of impurities and occurrence state. At the same time, the floatability has large differences because of the lack of lattice. For example, if there are silver, bismuth and copper in galena, its floatability is improved. If there are zinc, manganese and antimony, the floatability is weakened. The different impruties in galena cause the different effort of inhibitor. Cerussite is the major lead oxide. Generally after the vulcanization of Na2S, the flotation is carried out with advanced xanthate as collector. The suitable pH of vulcanization is about 9.5. If the pH is over high because of the large usage of Na2S, the NaHS can be used as the vlucanizing agent. Cerussite can be easily floated by fatty acid. However, it is difficult to separate with gangue minerals. Cerussite can also be easily collected by sting collector.

Cold rolling is a process by which metal is passed through rollers at temperatures below its recrystallization temperatures. The metal is compressed and squeezed, increasing the yield strength and hardness of the metal. Cold rolling of metal strip is a special segment within the metalworking industry.
