    Purchasing Cobalt and Molybdenum slags

    Our company purchases the following regularly:
    1. Cobalt and nickel Mix up materials, cobalt mud, rough cobalt sulfate, rough cobalt carbonate, rough cobalt hydroxide, rough cobalt chloride, rough cobalt nitrate and the alloy material with cobalt, nickel and copper contents. Metal material that include cobalt more than 7%, hydrochloric cobalt and hydrochloric manganese (cobalt content should be between 10%-12%) and so on. For Cobalt and nickel Mix up materials, the cobalt content should be more than 3% and the nickel content should be more than 8%.
    2. Mix up molybdenum catalyst, Mix up molybdenum compounds, Mix up molybdenum powder, Mix up molybdenum materials, and Mix up molybdenum alloy, etc. (Mo>3%). Mix up molybdenum, nickel, vanadium accelerant, and Mix up catalyst (Mo>3% no limit for other elements).Mix up materials from molybdenum smelter(Mo>3.5%).

    Mix up Catalyst
    The Mix up catalyst is mainly originated from petroleum industry, chemical industry and so on. The Mix up catalysts are provided with various categories and different metal contents. There are catalysts mainly made from the following metals such as Mo, Ni, Co, W, Al, Cu, Zn, V, Cr, Sn, and Mg.
    The Catalysts we often use and the metal contents are as follows:

    Catalyst Type

    Metal Content/%

    Catalyst Type

    Metal Content/%

    Molybdenum- Containing Catalyst

    MoO3 8-13%

    Zinc-Containing Catalyst

    ZnO 20-90%

    Nickel-Containing Catalyst

    Ni 2-25%

    Vanadium-Containing Catalyst

    V2O5 8-9%

    Tungsten- Containing Catalyst

    WO3 17-25%

    Tin-Containing Catalyst

    SnO2 4.5-5%

    Cobalt -Containing Catalyst

    Co 3-7%

    Chromium-Containing Catalyst

    Cr2O3 10-33%

    Aluminum- Containing Catalyst

    Al2O3 40-90%

    Magnesium-Containing Catalyst

    MgO 6-20%

    Copper- Containing Catalyst

    CuO 20-39%



    It is not allowed to mix sealed container, flammable, explosive, toxic, radioactive substance and medical Mix up materials into cobalt and molybdenum Mix up materials.
    The impurities having influence on environment and radioactive pollution substance in the import cobalt and molybdenum Mix up materials should be controlled according to GB16487.2, GB16487.7, and GB16487.9.
    The impurities on the cobalt and molybdenum Mix up materials surface should be cleaned up.
    Under transportable condition, the biggest external dimension of lump cobalt and molybdenum Mix up materials can be negotiated and determined by both parties of seller and buyer, and indicated in the contract.
    The cobalt and molybdenum in material should exist as metallic state or alloy, not the compound containing cobalt and molybdenum.
    Inspection Methods
    The status and cleaning degree of cobalt and molybdenum Mix up materials are usually inspected by eyes. If necessary, sampling can be taken to measure the weight and dimension. The methods of supplying Mix up cobalt and molybdenum materials, dealing with impurities, measuring external dimension and single block weight should be negotiated and determined by both parties and stipulated in the contract.
    The sampling method of cobalt and molybdenum materials and other relative matters should be negotiated and determined by both parties of seller and buyer.

    Inspection and Acceptance
    The inspection for Mix up cobalt and molybdenum materials could be consigned to the third party (such as AHK, SGS, and ALEX STEWART), the seller should guarantee the quality conforming to the stipulation of the contract.
