The Philippines is the second top producer of nickel in the world, second to Indonesia, but we export laterite nickel to China, South Korea, and Japan for processing. In turn, if we need processed nickel (for the production of stainless steel, batteries, parts for electronics, and others), we have to buy this from them.

This processing based on dissolution in water is called hydrometallurgy. Saprolite ores are treated by smelting, where the ore is dried and melted using energy from coal and electricity – often coal-based – to recover the nickel as an iron-nickel alloy. The iron-nickel alloy is generally used directly to make stainless steel.
High-pressure acid leach (HPAL) residue from laterite nickel ore is a potentially valuable resource for ironmaking; however, its efficient utilization is hindered by its high sulfur content. In this study, an effective and straightforward method is proposed for sulfur removal from HPAL residue. The process involves sieving and sodium carbonate …

The Agata North laterite nickel mineis located along the western range of the Surigao region of Mindanao and has an area of over 340ha. The mine is filled with nickeliferous laterite deposits within the mineralised plateaus along the Western Range. The laterites are believed to have formed due to chemical weathering of t…
