Treatment
From a technological point of view, it is most profitable to use ores rich in galena. Algorithm of production technology is represented by the following stages:
- Agglomeration firing;
- · Reductive melting;
- · Primary refining;
- Final refining.
At the final stage of production, ingots are produced, which are marked with a special marking. The conditions of their storage and transportation are regulated by the GOST standards. Supplier Avlob offers to buy any non-ferrous metal at a bargain price. The price is the best in this segment of rental.
Cleaning
Add saltpeter to the lead melt at 400−420 ° C. In this case, tin, antimony and arsenic are oxidized. These oxides dissolve upon addition to the melt of NaOH, forming an alkaline melt. It introduces sodium chloride to reduce the melting point and simplify the further extraction of metals. After the extraction of arsenic, tin and antimony from the mixture is completed, NaCl and NaOH are regenerated and returned to the process for processing the following portions of lead. This method makes it possible to obtain, at lower losses, a more pure metal-lead and noble metals,
Rolling
It is very soft and malleable material, perfectly bends, is stamped and rolled. Drilling and cutting also does not cause any difficulties. The ductility of a metal depends to a large extent on the content of additional impurities. Pure metal is characterized by good plasticity, easily lends itself to a variety of processing methods — stamped, pressed, and rolled to the thickness of the foil. Recall that lead itself is used as an important component of alloys.
