The Journey of Nickel: From Ore to Alloy

How is Nickel Extracted and Processed?

The extraction and processing of nickel are complex operations that transform nickel ore from the earth into the refined metal we use. The process begins with mining, which can involve both surface and underground techniques, depending on the type of ore being targeted. Sulfide ores are typically mined underground, where the nickel is more concentrated, making extraction more straightforward and less costly. In contrast, lateritic ores, found closer to the surface, are mined through open-pit methods but require more intensive processing due to their lower nickel content.

Once mined, the ore undergoes a series of treatments to concentrate and extract the nickel. For sulfide ores, this involves crushing, grinding, and flotation to produce a concentrated nickel sulfide product. This concentrate is then smelted and refined to produce pure nickel and other by-products. Lateritic ores, with their complex chemistry, often require hydrometallurgical processes, such as high-pressure acid leaching, to efficiently extract nickel.
