Can you refine cobalt NMS?

Excuse me, could you please elaborate on the possibility of refining cobalt NMS? I'm curious to understand the technical feasibility and potential challenges involved in such a process. Additionally, I'm interested in knowing if there are any specific methods or techniques that are commonly employed for refining cobalt NMS, and what kind of equipment or resources might be required. Furthermore, I'm wondering if refining cobalt NMS could have any significant impact on its properties or performance, and if so, how would that impact be manifested? Thank you for your time and consideration.
