Non-ferrous metals with a lowered boiling point are volatilized and removed in areas above 1,000°C within the rotary kiln.
The "chloride volatilization method" is a technique for removing non-ferrous metals by adding calcium chloride to a powder containing non-ferrous metal oxides (with iron oxide as the main component) to form pellets, and then subjecting them to heat treatment in a rotary kiln. This method separates and recovers non-ferrous metals from raw materials that contain both iron and non-ferrous metals, recycling each as ironmaking raw materials and non-ferrous refining raw materials. 【Features】 ■ Volatile removal of non-ferrous metals ■ An important process in resource recycling *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Resource Recovery Process Using This Method】 <Granulation Process> 1. Add calcium chloride to iron oxide powder containing non-ferrous metals such as copper, zinc, and lead, and then knead, granulate, and dry. 2. Calcium chloride is used as a chlorine source and simultaneously increases the strength of the dried pellets as a binder. 3. The strong dried pellets can withstand rolling in a rotary kiln, enabling stable firing. *For more details, please refer to the PDF document or feel free to contact us.
