Title (EN) PROCESS FOR MINERAL ORE FLOTATION IN THE PRESENCE OF MULTIVALENT METAL IONS
(FR) PROCÉDÉ DE FLOTTATION DE MINERAI EN PRÉSENCE D'IONS MÉTALLIQUES MULTIVALENTS
Abstract:
(EN) Processes for enriching a desired mineral from an ore comprising the desired mineral and gangue, are provided, wherein the process comprises carrying out a flotation process in the presence of one or more chelating agents, one or more collecting agents, one or more types of multivalent metal ions, and optionally, one or more depressants, in a solution, wherein the one or more chelating agents are capable, alone or as a group of compounds, of sequestering a metal or metal ion in the form of a metal-chelating agent complex that remains at least partially soluble in the solution.
(FR) L'invention concerne des procédés d'enrichissement d'un minéral souhaité à partir d'un minerai comprenant le minéral souhaité et une gangue, le procédé comprenant la mise en œuvre d'un procédé de flottation en présence d'un ou plusieurs agents de chélation, d'un ou plusieurs agents de collecte, d'un ou plusieurs types d'ions métalliques multivalents, et éventuellement, d'un ou plusieurs agents déprimants, dans une solution, ledit agent de chélation étant apte, seul ou sous forme d'un groupe de composés, à séquestrer un métal ou un ion métallique sous la forme d'un complexe métal-agent chélatant qui reste au moins partiellement soluble dans la solution.
