In Part 2 of this series we dig deeper into the specifics of laterites, one of the two main nickel ore types and look at smelting, the most common processing technique.
Let's dive into this new series of articles on sustainability, treatment processes and innovations in nickel production, starting with nickel ores.
Nickel can be found in many forms from nanowires to stainless steel alloys. But what are the properties of nickel that make it an essential element in batteries?
Materials selection for any piece of equipment or a process system is rarely a simple task, unless you are exactly replicating something successful. Often engineers will have a checklist to help them narrow down the choices, eliminating groups of materials that are not suitable for various reasons. Austenitic 300 series stainless steels containing 7-35% nickel will have most if not all of the boxes checked for being suitable where a stainless steel is desired.
The selection of an alloy should be guided by careful examination of the needs of the application. Before making a switch, it’s important to fully investigate an alloy’s strengths, weaknesses and applicability to your structure.
Most nickel production is destined for stainless steel. But a significant 8% is used in the production of alloy steels which are needed to deliver specific characteristics for specialised and often critical applications.
