Metalcess provides fuming furnace for non-ferrous metals smelting and recycling plant. Fuming furnace is a device used to recover volatile metals such as Lead, Zinc, Tin and Indium from the slag of non-ferrous metallurgy furnaces. It is widely used to treat various types of slag.
Fuming furnace is a device used to recover volatile metals such as Lead, Zinc, Tin and Indium from the slag of non-ferrous metallurgy furnaces. It is widely used to treat various types of slag (such as Copper slag, Lead-Zinc slag, tin slag, etc.) and refractory ores (such as low-grade Tin oxide concentrate, low-grade lead-zinc oxide ore, etc.).The advantages of fuming furnace include the ability to directly process molten slag, low fuel consumption, high metal recovery rate, simple operation and a relatively high degree of mechanization.
Application:
Lead-zinc smelting: Treating Zinc leaching residue, Lead fire-refining dross, Lead smelting slag and ISP process residue, replacing traditional rotary kilns.
Steel plant solid waste: Recovering Zinc (15-30% content) from electric furnace dust, solving the problem of dust accumulation.
Tin smelting: Extracting metallic tin from low-grade tin slag (Sn 2-5%).
Recycled resources: Treating electronic waste (PCB) and galvanized Zinc, recovering rare and precious metals.

Comprehensive recovery of multiple metals in single furnace: can simultaneously recover Zinc, Lead, Tin, Indium, Germanium and other metals, with an overall recovery rate of ≥85% (zinc ≥ 90%, lead ≥ 88%, indium ≥ 75%). The crude metals can be directly returned to the refining system, reducing raw material procurement costs.
High-efficiency and energy-saving: Oxygen-enriched combustion technology reduces fuel consumption by 25-40%, and waste heat power generation meets 30-50% of the equipment's self-power demand. Continuous operation capability, with a single furnace processing capacity of 100-500 tons per day (depending on the furnace capacity configuration).
Environmental protection: The flue gas is treated by two-stage dust removal (cyclone + bag filter) and wet desulfurization and denitrification (SO₂ ≤ 50mg/Nm³, NOx ≤ 100mg/Nm³, dust ≤ 10mg/Nm³), achieving ultra-low emissions.
Intelligent control: DCS + AI optimization system: Real-time monitoring of furnace temperature, oxygen potential, and metal vapor concentration, dynamically adjusting reducing agent and blower parameters. Digital twin model simulates process flow, predicting slag type changes and metal recovery trends.
