Cobalt prices have been quite low for quite some time. In the last year the price has varied from 19.50 to 14 $/lb, which is very cheap compared to 2007, during which the price reached a peak of 50$/lb.
Clearly 2007 was a particular year, because before and after that prices have never been so high. However, in the last three years the fall in the price has been considerable. Only in the last six month cobalt prices has continued to fall from slightly above 17$/lb with approximately 3$ per pound, but its current value is on a rise at 15$/lb.
