Molybdenum Concentrates
1.Trial Order Quantity
10.0 Metric Ton Minimum.
Regular Purchasing Order Quantity: 50.0 - 100.0 Metric Ton per month
2.Property
MoS2, lead grey color, at the similar color of graphite, metallic luster, hexagonal structure, and hexagonal flak.There is always pattern at the bottom, the texture is soft and slippery, the chip is thin but with flexibility. Specific Gravity: 4.7-4.8.
Hardness: 1.0-1.5.Melting Point:795oC.The streak is light-green grey or light green-black color, when MoS2 lacerates ceramic plate. Heating to 400-500oC, the MoS2 will generate to MoS3 easily. Both nitric acid and aqua regia all can make MoS2 decompose.

Important Notice
1)
The molybdenum concentrates of No.1 and No.2 categories in the above form getting from flotation method, the molybdenum concentrates of No.3 category in the above form getting from the comprehensive recovery of polymetallic ore.
2) The particle size requirement for molybdenum concentrates getting by flotation method should pass 200 mesh sieve, and the passing rate can not be less than 60%.The particle size of molybdenum concentrated getting by comprehensive recovery should be negotiated by both parties.
3) The sum contents of moisture and oil can not exceed 4% in molybdenum concentrates.
4) There can not be mixed with exotic materials and impurities in molybdenum concentrates.
4.Packing
There Are Two Kinds of Export Packing for Molybdenum Concentrates
1)Net weight 50.0Kg/Bag.The Inner packing is Glass Fiber Bag and the outer packing is Jute Bag.
2)Net weight 25.0-30.0Kg/Bag or 50.0Kg/Bag.The Inner packing is Latex Bag and the outer packing is Jute Bag.
