Nickel / cobalt mining extraction procedures
Sherritt Gordon Process. The nickel and cobalt metallurgy processes begin with an initial treatment of the mineral, re-concentrating it through crushing and flotation/gravity and obtaining a "speiss", rich in cobalt and nickel. The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air.

Ending Exploitation in the DRC's Deadly Cobalt Mines
In the DRC's artisanal mining sector —which exists alongside the formal mining industry—children and adults toil underground for hours in dangerous tunnels, using sticks or makeshift tools to mine for the cobalt-rich mineral heterogenite. Others sift ore in noxious, contaminated waters. With no protective equipment, injuries and deaths are common.
