Executive Summary
This technical report outlines the recovery methods for the Ferguson Lake Project, developed by Arithmetek, ACSI, and others. The proposed hydrometallurgical process is designed to minimize environmental effects and maximize energy efficiency, utilizing a chloride-based technology. The process treats bulk sulphide concentrate produced at the mine site and transported via pipeline to the Arviat processing facility.
The primary recovery method involves crushing and grinding ore to a coarse grind, followed by flotation to produce a bulk sulphide concentrate. This concentrate undergoes primary leaching with hydrochloric acid (HCl) at high temperatures, generating hydrogen sulphide gas which is converted to sulphuric acid. The process further utilizes oxidation and hydrolysis steps to precipitate iron as hematite while recycling HCl.
Base metals including nickel, copper, and cobalt are recovered from the leach solutions through a series of solvent extraction and electrowinning stages. The plant is designed to produce LME-grade metal cathodes and sulphuric acid, with excess power generation intended to make the operation energy self-sufficient. Capital costs were estimated at a scoping study level with +/- 40% accuracy.
