The sample achieved a nickel recovery of 63%, iron recovery of 31% and chromium recovery of 0.27%. The final nickel concentrates had a combined nickel grade of 46% and cobalt grade of 0.27%, while the magnetite concentrate had an iron grade of 55% and chromium grade of 3%. In addition, over half of the recovered nickel is reported to have a nickel sulphide concentrate 60%.
The company said the sample was also tested for its potential to transfer the metallurgical process at Crawford to the Reid ultramafic nickel mineralization. The company said it used a standard test process from the Crawford feasibility variability program, including grind sizes, reagent dosing strategies and flowsheet layout.
“As expected,” the company stated in a press release, “the nickel in the flotation circuit was recovered to a high grade concentrate due to the dominance of higher nickel tenor heazlewoodite mineralization.”
