Abstract
1. Способ подземного выщелачивания окисленных никель-кобальтовых руд, включающий вскрытие рудного тела системой закачных и откачных выработок, подачу в закачные выработки выщелачивающего раствора, подъем через откачные выработки продукционного раствора и его переработку, отличающийся тем, что месторождение делят на рудные блоки и последовательно их отрабатывают, при этом откачные и закачные выработки располагают вкрест движению подземных вод и ведут откачку никель-кобальтсодержащего раствора в интервале значений рН, обеспечивающим выпадение в осадок в недрах переведенных в раствор при выщелачивании балластных примесей, представленных, в основном, ионами железа и алюминия.2. Способ по п.1, отличающийся тем, что при величине рН продукционного раствора менее величины рН гидратообразования балластных примесей его откачку переносят в новые откачные выработки, располагаемые по и против потока движения подземных вод, а ранее использованные откачные выработки применяют в качестве наблюдательных.3. Способ по п.1, отличающийся тем, что при отработке рудного блока, примыкающего к контуру месторождения, откачные выработки располагают в безрудной зоне.4. Способ по п.1, отличающийся тем, что при величине рН продукционного раствора менее величины рН гидратообразования балластных примесей осуществляют его подачу в закачные выработки и последующий подъем из откачных выработок, располагаемых в безрудной зоне.5. Способ по п.1, отличающийся тем, что при величине продукционного раствора менее величины рН гидратообразования балластных примесей его подают на безрудный штабель с последующей переработкой профильтровавшихс1. A method for underground leaching of oxidized nickel-cobalt ores, including opening the ore body with a system of injection and pumping openings, feeding the leach solution to the pumping openings, lifting the production solution through the pumping openings and processing it, characterized in that the deposit is divided into ore blocks and sequentially work out, while the pumping and injection workings are arranged across the groundwater movement and pumping the nickel-cobalt-containing solution in the pH range, providing ypadenie precipitated in the depths transferred into solution in the leaching of impurities ballast represented mainly iron ions and alyuminiya.2. The method according to claim 1, characterized in that when the pH of the production solution is less than the pH of hydrate formation of ballast impurities, its pumping is transferred to new pumping excavations located on and against the groundwater flow, and previously used pumping excavations are used as observational. The method according to claim 1, characterized in that when mining the ore block adjacent to the contour of the deposit, the pumping excavations are located in the barren zone. The method according to claim 1, characterized in that when the pH of the production solution is less than the pH of hydrate formation of ballast impurities, it is supplied to the injection workings and the subsequent rise from the pumping workings located in the barren zone. The method according to claim 1, characterized in that when the value of the production solution is less than the pH of the hydrate formation of ballast impurities, it is fed to a barren stack with subsequent processing of the filtered
