  • TOMRA makes recovery promise to diamond …

    In kimberlite, the challenge is to recover 'needle in a haystack' diamonds, which requires controlled crushing of kimberlite ore to avoid damaging or breaking the diamonds. High waste dilution impacts the crushing energy needed and further increases diamond breakage risk. Utilising the company's NIR technologies can remove non-diamond bearing material, improving the crushing profile of ...
