which produced high grades of 1 per cent to 3 per cent.

Cobalt grades above 0.1 per cent are considered economic. Grades above 0.2 per cent are average and grades of 0.3 per cent and above are considered very good, especially with scale.

Cobalt is derived from the German word “Kobold”, which means Goblin. Like the creature from European folklore, cobalt caused mischief for miners when they tried to refine it.
