For example, the annual output of * * 10,000 tons of new lead-based alloy materials and rare and precious metals projects will be announced. Project name: Annual output of * * 10,000 tons of new lead-based alloy materials and rare and precious metals Project overview: The annual output of * * 10,000 tons of new lead-based alloy materials and rare and precious metals project is located in the factory area of * * Shuikoushan Zhihui Metallurgical Co., Ltd., with planned investment of * * * *. Auxiliary projects such as * * lead-based alloy workshop, gold and silver workshop, science and technology building, scum treatment workshop, canteen, raw material warehouse, water supply and drainage, roads, etc., the existing * 10,000 tons/year lead production line will be moved to * * lead-based alloy workshop, and the original lead-based workshop will be transformed into a warehouse. Maintenance workshops and office buildings will rely on existing projects. After the project is completed, the total area of the whole factory will reach * * * * *.

There are three new production lines in the project, among which the main process flow of the new lead-based alloy material production line is: electroplating lead → batching → alloy crucible melting → ingot casting → lead-based alloy. The main technological process of copper dross comprehensive recovery production line is: self-produced copper dross → batching → converter → copper matte. The main process flow of anode slime comprehensive recovery production line is: self-produced lead anode slime → reduction smelting in expensive lead furnace → vacuum refining → electrolytic refining → gold ingot and silver ingot. After the completion of the project, the annual output of lead-based alloy is * * 10,000 tons, copper matte * * * tons, gold ingot * * * kilograms and silver ingot * * * tons, and the by-product is refined bismuth * * * tons.
