Recently, the first high-grade nickel matte production line of a smelter in Indonesia was officially put into operation. After drying in the drying kiln, roasting in the rotary kiln and smelting in the oxygen-enriched side-blown furnace, high-grade nickel was successfully produced. This marks the world's first successful industrial application of oxygen-enriched side-blown furnace (OESBF) smelting process from laterite nickel ore, creating a new technological route for laterite nickel ore smelting and opening up a new technological way from laterite nickel ore to battery nickel raw material.

Indonesia is one of the countries with the most abundant laterite nickel ore resource in the world. High-grade nickel matte is the raw material for manufacturing high-purity nickel sulfate which is an indispensable core material for ternary precursors. The oxygen-enriched side-blown furnace process first used for producing high-grade nickel matte from laterite nickel ore will achieve better matching efficiency of resources and technologies and higher resource comprehensive utilization rates. The process is free of the "heat-electricity-thermal" conversion process, which will significantly reduce energy consumption and carbon emissions, and achieve environment-friendly and clean production.

PKU Pioneer's VPSA oxygen equipment has made it possible to generate enriched oxygen with lower energy consumption. Maturely applied in lead, copper and zinc smelting, injecting enriched oxygen into the side-blown furnace significantly speeds up fuel combustion and enhances its smelting efficiency. PKU Pioneer has provided reliable, stable and low-cost oxygen units for 40+ non-ferrous smelters worldwide and helped users optimize their non-ferrous metal smelting process and improve overall economic efficiency. PKU Pioneer has provided VPSA oxygen equipment with a capacity of over 100,000 Nm3/h for high-grade nickel matte production line, making us the preferred supplier of high-quality oxygen equipment for the non-ferrous metallurgy industry.
