Title (EN) METHOD FOR PROCESSING MINERAL MATERIAL CONTAINING ACID-CONSUMING CARBONATE AND PRECIOUS METAL IN SULFIDE MINERALS
(FR) PROCÉDÉ POUR LE TRAITEMENT DE MATIÈRE MINÉRALE CONTENANT DU CARBONATE AVIDE D'ACIDE ET DU MÉTAL PRÉCIEUX DANS DES MINÉRAUX SULFURÉS
Abstract: front page image
(EN)Processing of mineral material containing precious metal with one or more sulfide minerals and non-sulfide gangue minerals including acid-consuming carbonate may include preparation of a sulfide concentrate by flotation with the flotation or conditioning prior to flotation using a gas comprising carbon dioxide. Flotation may be at an acidic pH without prior decomposition of the acid-consuming carbonate and may be without addition of acid for pH adjustment.
(FR)L'invention porte sur le traitement de matière minérale contenant du métal précieux comprenant un ou plusieurs minéraux sulfurés et des minéraux de gangue non sulfurés comprenant du carbonate avide d'acide, pouvant comprendre la séparation d'un concentré de sulfure par flottation, la flottation ou le conditionnement avant flottation utilisant un gaz comprenant du dioxyde de carbone. La flottation peut se faire à un pH acide sans décomposition préalable du carbonate avide d'acide et peut se faire sans ajout d'acide pour l'ajustement du pH.
