Carbonation conversion lead smelting process
The process of carbonation conversion lead smelting is shown in the figure below. The lead ore is firstly introduced into air or oxygen at 50-60 ° C in ammonium carbonate solution, and stirred vigorously for several hours. Most of the lead sulfide in the ore is converted into lead carbonate and elemental sulfur, and most of the solution is returned to use after filtration. After partial treatment, the conversion slag is separated by floatation to remove precious metals such as elemental sulfur, gold and silver , and then dissolved by silicic acid. The amount of dissolved slag is small and can be discarded. The dissolved solution is a lead-containing silicic acid solution, which is insoluble. Anode electrolysis, the production of metal lead, after electrolysis, the liquid can be returned to dissolve and recycled. The lead-containing silicic acid solution can also be used as a raw material for the direct production of lead chemical products by adding a quantity of sulfuric acid to a lead-containing silicic acid solution, precipitating lead sulfate, and then producing lead by using lead sulfate as a raw material. products, these products such as: tribasic lead sulfate, dibasic lead phosphate, lead stearate, lead nitrate, lead chrome yellow, lead acetate, basic lead carbonate, red lead, and the like Huangdan. These products were originally produced from refined lead.
Mesh fence is also known as wire mesh fence, isolation fence, guardrail, etc. Metal fence mesh has the characteristics of anti-corrosion, anti-aging, anti-sun, and weather resistance. It can be widely used in important protected areas such as highways, railways, municipal fences, residential quarters, factory workshops, airport terminals, etc.
According to different materials, there can be Galvanized Wire Mesh Fence,Hot Dipped Welded Wire Mesh Fence,Hot Galvanized Wire Mesh Fence.
