Cobalt (Co) is a metal of great strategic and economic importance. The Museum is working with five UK universities on a multidisciplinary study, Cobalt: the roles of geology, geomicrobiology and geometallurgy in its mineral formation and recovery (COG3).
The COG3 project investigates potential solutions for the extraction of cobalt from reserves in Europe. It involves a consortium of international researchers with a wide range of scientific disciplines.
The project aims to:
We hope to unlock the UK's unique capabilities in the exploration, mining and recovery of cobalt.
Co is classified as an E-tech element by the Natural Environment Research Council (NERC) and as a critical element by the European Union's Raw Materials Initiative.
Around 55,000 tonnes of Co are produced globally each year. Less than 0.1% of this is produced within Europe, yet European countries use around 30% of globally produced cobalt.
Large untapped reserves of cobalt in Europe include:
One of the primary difficulties facing cobalt (Co) recovery from sulphide copper ores relates to its flotation when using conventional processes.
In order to recover Co, processing companies are considering increasingly complex chemical additives. The toxicity of these chemicals increases the potential environmental risk of the process, both in terms of volatilisation and leakage into the surroundings.
Lateritic and other oxidised Co-bearing ores, such as marine nodules, pose significant technical challenges in developing economical and environmentally benign approaches to Co extraction.
Recent advances in fields such as bio-processing ores and mineral concentrates have highlighted potential new techniques.
