Financial Controller

Who are we?

Seloxium Limited is a specialist critical metals recovery business, working with industrial manufacturers and mining operations to recover high‑value materials from waste streams. We are a fast‑paced company at an exciting stage of development, scaling our operations across two sites and an R&D laboratory facility in Oxford and a pilot processing plant in the North East of England.
