  • The anode is made of coarse or semi refined lead, the cathode is made of pure lead, and the electrolyte is composed of silicofluoric acid and lead silicofluoric acid. Anode: Lead is oxidized into lead ions and enters the solution: Pb-2e=Pb2+; Cathode: Lead ions in the solution are reduced to metal lead and precipitated: Pb2++2e=Pb. During the electrolysis process, impurities such as iron, zinc, tin, nickel, diamond, and other metals with a lower standard electrode potential than lead dissolve into the solution together; Metals with standard electrode potentials corrected for lead, such as antimony, arsenic, pound, copper, tin, gold, and silver, do not dissolve and form anode slime, which adheres to the anode surface. Electrolysis is the process of causing oxidation-reduction reactions on the cathode and anode by passing current through an electrolyte solution or molten electrolyte (also known as electrolyte). Electrochemical cells can undergo electrolysis under an applied DC voltage. The process of chemical changes caused by the passage of an electric current through a substance.

  • An ingot mold is a container or mold used in the casting process to shape and solidify molten metal into ingots. It is typically made of durable materials such as cast iron, steel, or graphite, and is designed to withstand the high temperatures and pressures involved in the casting process.

  • Eddy current sorting is a sorting technique that utilizes different conductivity of materials. Its sorting principle is based on two important physical phenomena: an alternating magnetic field that changes over time is always accompanied by an alternating electric field (electromagnetic induction law); A current carrying conductor generates a magnetic field (Biot Savart's law).

  • 01. Lead smelting The main raw materials for lead smelting are lead sulfide concentrate and a small amount of block ore. There are two methods for smelting lead: pyrometallurgy and wet metallurgy. Currently, pyrometallurgy is the main method in the world, and wet metallurgy of lead is still in the experimental research stage. The pyrometallurgical lead smelting process basically adopts the sintering roasting blast furnace smelting process, accounting for 85-90% of the total lead production; Next is the reaction melting method, which can be equipped with chamber furnaces, short kilns, electric furnaces, or vortex furnaces; Precipitation melting is rarely used. The refining of lead mainly adopts fire refining, followed by electrolytic refining, but due to customary reasons, electrolytic refining is not widely used in China. For difficult to separate sulfide lead zinc mixed concentrates, the closed blast furnace smelting method that simultaneously produces lead and zinc is generally used for processing. For the extremely difficult to separate mixed ore of lead and zinc oxide, a unique treatment method has been developed in China through long-term research, which involves using the raw ore or its enriched products of the mixed ore of lead and zinc oxide, sintering or pelletizing them, and melting them in a blast furnace to obtain coarse lead and molten slag containing lead and zinc. The slag is further fumigated in a fuming furnace to obtain zinc oxide products, and electrolytic zinc is obtained through wet zinc smelting. In addition, zinc oxide products can also be directly fumigated using a rotary kiln.

  • Lead and zinc are widely used in fields such as electrical industry, mechanical industry, military industry, metallurgical industry, chemical industry, light industry, and pharmaceutical industry. In addition, lead metal has many uses in sectors such as the nuclear industry and petroleum industry. More than 80% of the world's lead is used to produce lead-acid batteries.

  • Battery dismantling machines Battery dismantling machines (battery dismantling machines, battery dismantling machines) easily disassemble waste batteries. If electric vehicle batteries and car batteries are directly disposed of, they pose a significant risk and require centralized recycling for harmless treatment. Therefore, we will use our company's waste battery dismantling machine. The battery car battery dismantling machine equipment uses manual feeding to push waste batteries into the body. The propulsion system pushes the batteries into the position to be cut, and the crank drives the cutting blade to accurately cut off the waste battery cover. The cutting blade can be adjusted, and the propulsion system pushes the next battery forward again.
