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%.
2.21 Main Source: 1.Dust or slag from Cu, Pb, Zn and other non-ferrous Smelter .2.Caked antimony oxide when smelting Sb; 3.Sb dust from Pb smelter after recycling Pb from dust.
2.3 Sb≥70% Pb/Sb≤0.30% As/Sb≤0.8% moisture≤2% considered as standard antimony oxide powder, it is applicable for producing standard antimony ingot and the pricing will be the highest.
