Project Solution
Product Application
Darnal's cutting-edge and proven metallurgy equipment is specifically engineered for the smelting of metal ores and concentrates, including silver (Ag), gold (Au), platinum (Pt), copper (Cu), zinc (Zn), lead (Pb), tin (Sn) and other metals. Additionally, it facilitates the processing of scrap metals and smelting by-products, such as oxides and sulfides like anode slime or smelting slag, which also contain these valuable metals. This advanced technology empowers users to efficiently extract high-purity metals from the aforementioned raw materials, which can then be cast into ingots designed for international market distribution.
