To avoid the adverse effects of antimony on the cyanide leaching process used for the recovery of gold from refractory gold ore, a cleaner production process was proposed that would selectively remove antimony as sodium pyroantimonate. The process included three steps: 1) leaching of antimony from the refractory gold ore with sodium sulfide solution; 2) pressure …

Stibnite is a historical mining operation that produced antimony for war efforts in the 1940s and 1950s and then was abandoned following a series of smaller gold operations. Perpetua's plan for Stibnite is "as much about restoring the site as it is mining it for the much-needed critical mineral antimony and gold," according to the company website.
