For smelting matte, blast furnace has wide adaptability, high hearth efficiency, and high thermal efficiency. So in history, it is one of the most important copper smelting methods. Traditional blast furnace top is open, only can handle lump ore or agglomerate, flue gas contains low concentration of SO2, it is not easy to effectively recycle and has envi

The input quantity Each input quantity of blast furnace depends on the furnace size,large furnace can reach 1～3.5t ,small furnace just can reach 100～500kg.Feeding time interval usually be 10 ~ 20 min, material surface wave can not more than 0.5 m before and after feeding.

After the lead burden reduction smelting in blast furnace, we can obtain all kinds of smelting products as below: crude lead, lead matte, arsenic matte, soot and slag.

The blast furnace remains an important part of modern iron production. Modern furnaces are highly efficient, including Cowper stoves to pre-heat the blast air and employ recovery systems to extract the heat from the hot gases exiting the furnace. Competition in industry drives higher production rates. The largest blast furnaces have a volume around 5580

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally iron, but also others such as lead or copper.

The main ingredients of matte: Cu2S - FeS, a little other metal sulfides (such as Ni3S2, Co3S2, PbS, ZnS and so on), precious metals (Au, Ag), platinum group metal, trace amount of Se, Te, As, Sb, Bi and other elements. The basic principle of converting, simply, is to remove almost all iron and sulfur in liquid matte by using oxygen in the air, at the same t
