Revolutionizing the processing of ultra-high silica complex copper concentrates, BGRIMM has developed a high-intensity, high-temperature oxygen-enriched side-blown smelting furnace and introduced the world’s first fully hot “three-furnace continuous copper smelting” process: side-blown smelting → bottom-blown converting → anode refining.
This integrated flowsheet delivers outstanding performance:
1. Copper & precious metal recovery rates exceeding 98%
2. Smelting capacity: 100–150 t/(m²·d)
3. Specific energy consumption as low as 150–250 kg standard coal per tonne of product
4. Emissions of heavy metals and SO₂ meet or surpass international advanced levels
Proven reliable, energy-efficient, and highly reproducible, this process provides a cleaner, more economical route for copper, precious metals, and secondary resource smelting. Ideal for smelters aiming to lower capex, opex, and environmental footprint while maximizing metal recovery.
