Abstract
1. Способ выщелачивания металлической меди из медьсодержащего материала в растворах серной кислоты с добавкой окислителя при нагревании и наложении переменного тока промышленной частоты с использованием нерастворимых электродов, отличающийся тем, что выщелачивание ведут в режиме перколяции выщелачивающего сернокислого раствора через слой медьсодержащего материала, при этом контролируют и поддерживают содержание меди в выходящем растворе в пределах 20-30 г/л регулированием расхода выщелачивающего раствора, причем в качестве окислителя используют раствор перекиси водорода с концентрацией 5-10%.2. Способ по п. 1, отличающийся тем, что при выщелачивании нерастворимые электроды погружают в слой медьсодержащего материала, реактор герметизируют, при этом подачу раствора перекиси водорода прекращают при возникновении избыточного давления внутри реактора и возобновляют при снижении давления, причем перекись водорода подают непосредственно в реакционную зону отдельно от выщелачивающего сернокислого раствора.1. The method of leaching metallic copper from copper-containing material in sulfuric acid solutions with the addition of an oxidizing agent when heating and applying alternating current of industrial frequency using insoluble electrodes, characterized in that the leaching is carried out in the mode of percolation of the leaching sulfuric acid solution through a layer of copper-containing material, while controlling and maintain the copper content in the effluent solution in the range of 20-30 g / l by controlling the flow rate of the leach solution, moreover, as oxidize I use a hydrogen peroxide solution having a concentration of 5-10% .2. The method according to claim 1, characterized in that during leaching, insoluble electrodes are immersed in a layer of copper-containing material, the reactor is sealed, and the flow of hydrogen peroxide solution is stopped when excessive pressure occurs inside the reactor and resumed when pressure is reduced, and hydrogen peroxide is fed directly into the reaction zone Separated from leaching sulphate solution.
