摘要： Disclosed is a method for treating heap leach stacks by applying an insoluble polyimide composition, such as polysuccinimide, to the surface of an ore stack and/or incorporating the insoluble polyimide composition throughout the ore stack. The insoluble polyimide composition is then exposed to an aqueous solution to initiate hydrolysis and produce one or more water soluble products, such as hydrolyzed polyimides, polycarboxylates, polycarboxylic acids and mixtures thereof that will permeate the ore stack at a concentration sufficient to suppress scale formation within the leach stack. The water soluble products may also act to suppress scale formation in piping and channels peripheral to the leach stack, thereby reducing maintenance expenses.

摘要： A method of leaching a metal value from a heap of a metal-containing ore and a heap leaching operation are disclosed. The method includes establishing a downward flow of a leach liquor through a section of the heap by supplying the leach liquor onto a top surface of the section and allowing the leach liquor (containing metal values in solution) to drain from a lower part of the section. The method is characterized by supplying the leach liquor onto the top surface of the section at a flow rate that is sufficient so that the downwardly flowing leach liquor saturates the section of the heap.

摘要： The present invention relates generally to a process for removing dissolved or colloidal silica from a pregnant leach solution (“PLS”). More particularly, an exemplary embodiment of the present invention relates to a, process which mixes PLS with an acid source, preferably lean electrolyte, to induce formation of colloidal silica that can then be collected and removed. Additionally, in an exemplary embodiment of the present invention, at least one silica seeding agent is added to induce formation of colloidal silica, at least one flocculant is added to induce aggregation of the colloidal silica, and a solid-liquid separation process is utilized to remove advantageous amounts or substantially all of the colloidal silica, thereby providing relief from supersaturation of dissolved silica in the metal recovery processes.
