    The purchase quality standard of antimony ore and the price stipulation


    Antimony mineral sand (include: lump ore, powder ore, floating selected sand mine)
    1.Quality Standard
    1.1 Pb/Sb≤0.35% As/Sb≤0.8%.
    1.2 Lump ore particle size: exceed 30mm, less than 150mm.
    1.3Lump Standard: Sb≥20% or 5%≤Sb<30%, Powder ore standard Sb≥25%,Floating selected sand mine standard: Sb≥30%. If the content of Sb is lower than the standard, quality and price will be renegotiated by both of seller and buyer.
    2. Price Stipulation of Quality and Impurity, Rejection Standard
    Considered 30% antimony content as benchmark price, price increase USD100/MMt for every 5% increase of content, but no increase if content is higher than 60%.
    40.01-50%, if 5% above, thus increase USD 100/MMt
    30.01-40%, if 5% above, thus increase USD 80/MMt
    20.01-30%, if 5% below, thus decrease USD 150/MMt
    15.01-20%, if 1% below, thus decrease USD 200 /MMt
    2.2 Pb/Sb, if 0.01% exceeds, thus decrease USD 20 /MMt
    2.3 As/Sb, if 0.1% exceeds, thus decrease USD 20 /MMt
    2.4 If Pb/Sb>2% or As/Sb>3%,It will not be considered as standard antimony ore and the price should be renegotiated.
    3. Confirmation of Sulphide Mineral,, Mixed Mineral and Oxide Mineral and Price Reduction Standard
    3.1 S/Sb≥20% defined as sulphide mineral, 16%≤S/Sb<20% defined as mixed mineral, S/Sb<16% defined as oxide mineral.
    3.2 Mixed mineral Sb≥16%, Price determined: USD 500 /MMt reduce from the same grade of sulphide mineral. Oxide mineral Sb≥25%, Price Determined: USD 1000 /MMt reduced from the same grade of sulphide mineral.
    Antimony ore with high content of As-Pb
    1. Quality Aspect
    1.1. The requirement of Sb content will be decided by the quantity of antimony ore.
    1.2 If quantity is more than 5000 ton per lot and antimony content is more than 6%, we can purchase it under the no requirement of other elements.
    1.3. If quantity is more than 3000 ton per lot and antimony content is more than 8%, we can purchase it under the no requirement of other elements.
    1.4 Oxide ore or Sulfide ore won’t be affected by high content of As and Pb.
    2. Price will be determined according to the content of each element and processing cost.

    Antimony ore with heavy metal over the standard
    1. There is no strict requirement for quality, because we have advanced technology and equipments, and most of materials could be dealt with.
    2. The quantity we require must reach to 2000Mt/ lot at least as the more quantities, the lower processing cost. It is better if there’s long-term contract.
