Nonferrous metal smelting is the process of extracting nonferrous metals from ores, concentrates, secondary resources or other materials and processing them into products with certain properties.
Rotary kiln is an important equipment for nonferrous metal smelting. For example, in the smelting of copper concentrate, a rotary kiln is used for roasting to remove impurities such as sulfur and arsenic in the concentrate, and to produce roasted sand for subsequent smelting processes; when processing laterite nickel ore, the rotary kiln can dry and pre-reduce the ore to create conditions for subsequent nickel iron production; lead and zinc concentrate is oxidatively roasted in a rotary kiln to convert the sulfide therein into oxides, and then further extract lead and zinc.
Suitable for Copper ore, laterite nickel ore, lead-zinc ore, tin ore, bauxite, etc.
The rotary kiln is an inclined rotating cylinder. Nonferrous metal raw materials are fed in from the high end and slowly move to the low end as the cylinder rotates. During the movement, the raw materials are fully exposed to the high-temperature airflow in the kiln, and physical and chemical changes occur. The heat is provided by fuel combustion to maintain the high-temperature environment in the kiln, meet the reaction conditions required for nonferrous metal smelting, and realize the processes of ore decomposition, roasting, reduction, etc.

1. Strong adaptability: It can process a variety of non-ferrous metal raw materials of different properties and grades, including complex and difficult-to-select ores.
2. Large processing capacity: It can be produced continuously, with high output, suitable for large-scale industrial production.
3. High thermal efficiency: The rotary kiln has a long barrel, the material stays in the kiln for a long time, can be fully in contact with the hot air flow, and has a high heat utilization rate.
4. Flexible operation: The smelting process and product quality can be flexibly controlled by adjusting parameters such as fuel type, amount, kiln speed, etc.
