Abstract
Based on analyzed redistribution of nonferrous and precious metals in aqueous and weak acid solutions passed through copper–nickel ore dressing refuses, the authors have obtained distribution of the metals in mineral phases for different levels of filtering layer in the tailings and for different contact solutions. Potential extractability of gold and platinum at 28.4 and 3.9% of the total quantity of mine refuse, respectively, using weak acid contact solution is shown in the article.
