Abstract
Способ кюветно-скважинного выщелачивания металлов из руд, специальных отвалов и лежалых хвостов обогащения, включающий обработку минеральной массы раствором выщелачивающего реагента в кюветах и выделение металла из продуктивного раствора, отличающийся тем, что кюветы формируют по выщелачиваемой массе, в днище кювет сооружают систему закачных и откачных скважин, расположенных выше уровня днища кюветы и глубиной не менее нижней отметки выщелачиваемого слоя минеральной массы, производят заполнение кювет агломерированной минеральной массой или пульпой, приготовленной из ранее извлеченного материала, осуществляют обработку минеральной массы в кюветах раствором выщелачивающего реагента и выделение металла из продуктивного раствора, затем полученный после выделения металла оборотный раствор доукрепляют или заменяют на раствор другого состава и подают в систему закачных скважин для выщелачивания нижних слоев материала, затем откачивают рабочий раствор с выщелоченным металлом через систему откачных скважин и производят выделение из него металла, при этом для выщелачивания нижних слоев материала используют растворы экологически безопасных реагентов, например, хлоридов или тиосульфатов.The method of ditch-well leaching of metals from ores, special dumps and stale tailings, including the treatment of the mineral mass with a solution of a leaching reagent in the ditches and the extraction of metal from the productive solution, characterized in that the ditches are formed according to the leached mass, in the bottom of the ditches, a system of injection and pumping out wells located above the level of the bottom of the cuvette and with a depth of at least the lower mark of the leached layer of mineral mass, fill the cuvettes with agglomerated mineral mass or pulp prepared from previously extracted material, process the mineral mass in the cuvettes with a solution of a leaching reagent and separate metal from the productive solution, then the circulating solution obtained after metal separation is reinforced or replaced with a solution of a different composition and fed into the injection wells system for leaching the lower layers of the material, then the working solution with the leached metal is pumped out through the rejection system wells and produce metal from it, while leaching the lower layers of the material use solutions of environmentally friendly reagents, for example, chlorides or thiosulfates.
