Oxygen-Enriched Combustion and Non-Ferrous Metals Smelting

In the smelting of non-ferrous metals such as copper and nickel, oxygen plays a vital role throughout the entire metallurgical process. It boosts furnace temperatures, reduces fuel consumption, and plays a key role in refining to enhance metal purity. Using copper smelting as an example, oxygen is particularly critical in the following two stages:

Smelting Stage: Reducing Energy Consumption through Oxygen Enrichment

During the initial smelting process—typically performed in high-temperature furnaces such as flash or bath smelters—copper concentrate is heated to over 1,200°C. This breaks down sulfide ores and produces a semi-refined product known as matte, which contains around 40%-70 % copper. By enriching combustion air with oxygen, the process generates enough internal heat, which significantly reduces the need for supplemental fuel and improves energy efficiency.

Converting Stage: Oxygen as a Key to Removing Impurities

Following the smelting stage, the matte undergoes further processing in converters, where oxygen-enriched air is injected to oxidize and remove remaining iron sulfide (FeS) and sulfur. This step increases the copper purity to 97% or higher. In this phase, oxygen is not only a reactive agent but also enhances the efficiency of the overall reaction, leading to improved recovery rates. A reliable and efficient oxygen supply is therefore essential for achieving high-purity copper production.

JLOX Series Molecular Sieves: Enabling Efficient Oxygen Generation

JALON’s flagship molecular sieves JLOX series, are the core material used in Pressure Swing Adsorption (PSA) and Vacuum PSA (VPSA) oxygen generation systems. These systems selectively adsorb nitrogen from the air, enabling oxygen enrichment on-site in a more cost-effective and energy-efficient manner compared to traditional cryogenic processes.

We cordially invite mining, metallurgy, and gas separation professionals from around the world to visit our booth. Let’s explore the future of energy-efficient oxygen supply together!
