BGRIMM's Oxygen-Enriched Side-Blown Smelting Technology

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.
