Process for extraction of metals in wet Solid Sorption and leaching

摘要

Provides a hydrometallurgical process for the selective extraction of one or more Target metals from ores, Concentrates, Tailings, slag and other solid sorption simultaneously leaching ore, combining with the State of Wet solids.The sorption is carried out by means of Sorbents, such as activated carbon, Ion Exchange Resins, Zeolites, among others, and their mixtures.The process comprises the steps of: (a) mixing the solid ore leaching with acid or basic agents, one or more Sorbents and a sufficient quantity of water to moisten the substantially Solid ore as the Sorbent without forming a suspension,To obtain Wet Solids; (b) conducting Sorption and leaching Wet Solids; (c) dilute Wet solids and preparing a Slurry by adding an aqueous solution; (d) to separate the Sorbent Loaded Pulp; (e) to elute (Desorber) Metals target from the Sorbent Loading With an eluent a eluateReturning to the Sorbent then returned to the mixing Phase (a); and (f) to recover the metals from the eluate to obtain one or More Metal Products late returning back to the eluent, the elution STEP (e). The Invention has the main advantage to improve the Recovery of metals at a reduced rate of leaching Agent consumption
