Lead Anode Slime Treatment-Lead- Metalcess

Lead Anode Slime Treatment. Anode slime is a byproduct from copper or lead electro-refining process. The copper/lead anode slime usually contains As, Sb, Bi and precious metals like gold and silver. Smelter of anode slime is most likely divided into two groups by the two different recovery processes based on its property and treatment capacity1. Wide adaptability to raw material, from iron, copper, copper-nickel, zinc, lead and zinc-lead complex concentrate; 2. Application of rich-oxygen air blast offers high smelting temperature, enhances hearth capacity and generates high concentration SO 2 gas suitable for sulfuric acid-making; 3.Copper Blast Furnace Smelting-Copper-

Copper

Copper. face-centered cubic (fcc) Copper is a chemical element; it has symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, asLead Sulfide Ore. Lead & zinc metals are closely attached to each other and usually mined together from primary ore, for example, Galena (PbS) & sphalerite (ZnS) are associated in native ore. As the main formation of lead sulfide, galena is widely spread all over the world. The other source of lead sulfide are boulangerite/ jamesonite/ bournonite.Lead Sulfide Smelting- Metalcess

Zinc Leaching and Purification-Zinc- Metalcess

Zinc Leaching and Purification. Typical process of zinc hydrometallurgy consists of zinc concentrate roasting, calcine leaching, electro-winning, ingot casting and acid-making. Zinc leaching is performed in diluted sulfuric acid system or ammonium system. The leaching acidity, temperature and pressure are regulated to achieve the most optimalFor example, galena (PbS) and sphalerite (ZnS) are detected as associated minerals in natural mines. Most of zinc metal production are from zinc sulfide ore, which mainly exists in the form of sphalerite, maramatite and wurtzite. Zinc oxides are found in smithsonite, hemimorphite, willemite and hyrdozincite. Recommended Process:Zinc Hydrometallurgy
