COLLECTOR AND FROTHING AGENT FOR FLOTATION BASED ON ORGANIC RESIDUES TO RECOVER METALS FROM MINERALS BY FROTH FLOTATION, COLLECTOR AND FROTHING AGENT RECOVERY PROCESS AND FOAMING FLOTATION PROCESS THAT USES THE COLLECTOR AND FROTHING AGENT

摘要

The present invention involves a multifunctional frothing agent with collector and frothing functions for frothing flotation processes to recover valuable metals from minerals, based on organic residues selected from biosolids from wastewater treatment plants, organic sludge from biogas production systems, compost hydrosoluble organic matter or other similar biologically treated or stabilized organic in aerobic or anaerobic conditions, industrial sludge from industrial organic liquid waste treatments, hydrosoluble organic matter from vegetal peat, manure, dung or a combination of two or more of these, or a fraction of them, representing between 35% and 98% organic matter, apparent density between 0.2 and 0.8 g/mL, a pH between 6.0 and 8.5, an electrical conductivity between 4.0 and 15 mS/cm. It also involves the process of the multifunctional collector and frothing agent recovery (collector and frothing agent) and the frothing flotation process that uses the multifunctional agent disclosed in this investigation.
