Abstract
1. Способ извлечения металлов из руд и промышленных отходов, включающий дробление сырья, его отсыпку в форме штабеля, предварительную обработку сырья в штабеле, обработку штабеля выщелачивающим раствором, растворение металлов и получение продуктивного раствора с извлечением из него металлов, отличающийся тем, что предварительную обработку сырья в штабеле производят подачей в штабель раздельно или в виде смеси растворов, содержащих поверхностно-активное вещество и гипохлорит, а обработку штабеля проводят выщелачивающим раствором, полученным смешением в объеме штабеля при подаче в него раздельно или в виде смеси растворов, содержащих гипохлорит, поверхностно-активное вещество и/или минеральную кислоту. ! 2. Способ по п.1, отличающийся тем, что предварительную обработку проводят последовательной подачей в штабель растворов поверхностно-активного вещества и гипохлорита. ! 3. Способ по п.1, отличающийся тем, что предварительную обработку проводят смесью растворов ПАВ и гипохлорита. ! 4. Способ по п.1, отличающийся тем, что в выщелачивающем растворе используют смеси минеральных кислот или последовательно вводимые минеральные кислоты. ! 5. Способ по п.1, отличающийся тем, что места подачи растворов в объем штабеля могут не совпадать. 1. A method of extracting metals from ores and industrial waste, including crushing raw materials, filling them in a stack, pretreating raw materials in a stack, treating a stack with a leaching solution, dissolving metals and obtaining a productive solution with the extraction of metals from it, characterized in that pretreatment raw materials in a stack are made by feeding them into a stack separately or in the form of a mixture of solutions containing a surfactant and hypochlorite, and the stack is treated with a leaching solution obtained by mixing in the volume of the stack when fed into it separately or as a mixture of solutions containing hypochlorite, surface active substance and / or mineral acid. ! 2. The method according to claim 1, characterized in that the pre-treatment is carried out by sequential feeding into the stack of solutions of a surfactant and hypochlorite. ! 3. The method according to claim 1, characterized in that the pre-treatment is carried out with a mixture of surfactant and hypochlorite solutions. ! 4. The method according to claim 1, characterized in that mixtures of mineral acids or sequentially introduced mineral acids are used in the leaching solution. ! 5. The method according to claim 1, characterized in that the places for feeding the solutions into the volume of the stack may not coincide.
