  • Delivery Residual pole scrubber to our clients
    Delivery Residual pole scrubber to our clients

    Residual pole scrubber In the process of electrolytic refining of lead by residual electrode scrubber, the metal lead loses electrons in the anode and becomes lead ions which enter the electrolyte, in addition to a small part of the impurities in the anode and lead dissolved in the electrolyte, the vast majority of insoluble and adhere to the anode surface to form anode slime. The anode slime contains a lot of lead, antimony, bismuth and precious metals such as gold and silver, so the attached anode slime and residual acid must be cleaned and recycled to reduce repeated smelting. At present, there are three kinds of washing equipment in China: horizontal residual electrode washing machine, vertical residual electrode washing machine, rotary residual electrode washing machine.

  • Detailed explanation of copper process flow
    Detailed explanation of copper process flow

    The smelting methods for producing electrolytic copper from copper concentrate in the world are divided into two categories: pyrometallurgical and wet smelting. At present, over 80% of the refined copper production is produced by pyrometallurgy, and about 20% of the refined copper is produced by hydrometallurgy. The detailed information is as follows.

  • The Working Principle of a Rotary Furnace
    The Working Principle of a Rotary Furnace

    A rotary furnace is a barrel-shaped instrument that is rotated around its axis when performing heat treatment. These instruments are tilted slightly to allow the sample under heat treatment to be passed from one end of the barrel to the other. This sample transfer occurs as the rotary furnace rotates, and this rotation can also induce some mixing or stirring of the sample. When the rotary furnace is in operation, hot gases pass through the chamber to perform the heat treatment. Generally, the hot gases pass through in the opposite direction than the sample, but depending on the application requirements they can also pass through in the same direction.

    How to distinguish between gray cast iron and cast steel?

    How to distinguish between gray cast iron and cast steel? Gray cast iron carbon mainly crystallizes into graphite and exists in the form of flakes in cast iron, with dark gray fracture surface, making it a common cast iron component. The chemical composition of gray cast iron is generally 2.6%~3.6% C, 1.2%~3.0% Si, 0.4%~1.2% Mn, ≤ 0.3% P, 0.15% S. Cast steel is an important metal structural material with excellent comprehensive mechanical and physical and chemical properties. Compared with cast iron, cast steel has higher strength, plasticity, toughness, and good weldability. If you are referring to these two results, you can use a file to judge them based on their different hardness. You can first find a standard gray cast iron component and then use the same new file to file on the surface of both components. If it feels like the hardness of two pieces is the same, it is judged to be gray cast iron; If the file is judged to be slipping or noticeably harder than standard gray cast iron parts, it is judged to be cast steel.

  • The relationship and differences between cathode copper, anode copper, and 1 # electrolytic copper
    The relationship and differences between cathode copper, anode copper, and 1 # electrolytic copper

    Electrolytic purification of copper: Coarse copper (containing 99% copper) is pre made into thick plates as the anode, pure copper is made into thin plates as the cathode, and a mixture of sulfuric acid (H2SO4) and copper sulfate (CuSO4) is used as the electrolyte. After being electrified, copper dissolves from the anode into copper ions (Cu) and moves towards the cathode, After reaching the cathode, electrons are obtained and pure copper (also known as electrolytic copper) is precipitated at the cathode. Impurities such as iron and zinc, which are more active than copper, dissolve together with copper to form ions (Zn and Fe). As these ions are less likely to precipitate compared to copper ions, adjusting the potential difference appropriately during electrolysis can prevent these ions from precipitation at the anode. Impurities such as gold and silver, which are less active than copper, deposit at the bottom of the electrolytic cell The copper plate produced in this way is called "electrolytic copper" and has extremely high quality, which can be used to make electrical products. The sediment at the bottom of the electrolytic cell is called "anode mud", which is rich in gold and silver and is very valuable. It has extremely high economic value when taken out and processed Electrolytic copper=cathode copper
