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.
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.
Think of the largest cruise ship. Then imagine how much it weighs – just over 100,000 tonnes, in fact. Now think about 500 of those ships, and what they weigh. That is the staggering amount of new electronic waste that we generate every year.
Even small quantities of nickel in an application can make a big difference to successful deployment.
The many new and innovative applications of hydrogen as fuel show great promise for a greener future.
The present-day principal driver in the Li-ion industry is the large batteries required for electric vehicles. Due to the size of these batteries and the relative growth of electric vehicles it is predicted that the total Li-ion energy capacity will exceed one tera watt-hour by 2030. This anticipation for a dramatically rapidly expanding industry has stakeholders all along the value chain very motivated to be ready.
The last three months have been unprecedented. But amidst the chaos and despite the drop in global GDP, there has still been a considerable amount of activity in the electric vehicle (EV) and battery world.
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.
