purchase antimony ore and primary antimony oxide
Date:2013-03-12     Count:3684
We purchase antimony ore and primary antimony oxide,
antimony ore indicators and harmful elements requires the approach of excessive harmful elements.
 Imported packaging, shipping considerations. Minimum delivery amount. The SGS inspection reports or other description of the content of the proof before signing the contract.
Antimony Description: (metal nature, purposes)
Antimony is a silver metal is an acid-resistant material, at room temperature, the relative density of 6.68, m.p. 630.5 ° C. Brittle, non-malleable. Is a poor conductor of electricity and heat, not easily oxidized at room temperature, and corrosion resistance. Antimony alloy main role is to increase the hardness, often referred to as metal or alloy hardener. Antimony and antimony compounds are the first to use the wear-resistant alloy, printing type metal on the military-industrial manufacturing bullets, artillery shells, warheads; to battery plates submarine cable foreskin. With the development of science and technology, it is now widely used in the production of flame retardants, enamel, glass, rubber, paint, ceramics, semiconductor components, fireworks, pharmaceutical and chemical sectors.
The antimony metal affinity copper, but also pro-oxygen. Amphoteric element characteristics. Ions Sb3 is +, also Sb5 + the various antimony concentrate, are used pyrometallurgical process to the production of various antimony products, such as antimony oxide, antimony white (Sb2O3), and the Health and antimony (acicular antimony trisulfide).

Note:
1.There should be proper price reduction if the harmful elements exceed the standard
2.The oxide antimony ore can refer to the above specification and should be reduced the price by the Sb content. The cost of smelting antimony oxide 
ore is higher than the antimony sulfide ore. Pricing regulation refer to Group’s price list.
3.  Antimony Ore relevant Specification and Stipulation for Harmful Elements: Our Group could deal with the materials with content of harmful elements exceeding the standard. 
4.  Imported Materials' Packing: We prefer 1 Mt/bag; Attention of shipment: The anticipation of offering 14days free detention of containers at destination port; Quantity: 100Mt min.

Note:
1. There should be proper price reduction if the harmful elements exceed the standard
2. The oxide antimony ore can refer to the above specification and should be reduced the price    based on the Sb content.
3. Our company provides the technical service of antimony concentrating; treat with mine tailing and recycling. We would also like to cooperate on dealing with antimony mine tailing.
4. In addition, we can offer the technical service of deep processing and cooperation to process antimony raw material.
This standard is applicable for the antimony concentrates getting from mineral processing and antimony smelting. 
(1) The moisture content in the concentrates should be less than 14% and also less than 8% during heating-period. 
(2)Other impurities should not be mixed into the concentrates. 
(3)Packing: The concentrates most have been delivered by container transport, packed with ton bag. The same grade can be classified as one lot.

Inspection Method. 
The inspection carried out at the loading port is to determine the letter of credit amount. The inspection carried out by AHK, ALEX, SGS or CCIG at the port of discharge should be final for both parties of seller and buyer. The regular customer could be amortized by TT, according to inspecting by each other. 

The others as per the international practice.

Rough Antimony Oxide Powder
Rough Antimony Oxide Powder (Include Antimony Oxide Powder, Powder-sticking Antimony Oxide, , Caked Antimony Oxide, Antimony Oxide with High As, Antimony Oxide with High Impurity)
1. Quality Standard 
Antimony content should be more than 10%.
2. The Grade Determination & Method of Calculating Price 
We can purchase Sb≥10%,and other metals total content should be more than 25%. Price is determined based on the content of Sb and other elements separately.
2.11 Main Sources: 1.Flue dust from smelting lead; 2.lead slag containing Sb from refining zinc by hydrometallurgy; 3. Flue dust from copper smeltery; 4.Antimony ash or slag containing sb from other non-ferrous metals smelting plants.
2.2 70%>Sb≥30%,purchase in large quantity. If As<1.5%,no price deduction; 10%>As>1.51%, the pricing will be effected by As, If As>10.01%.
