Abstract

Изобретение относится к способу предварительной обработки сырья, поступающего в поверхностный биореактор без перемешивания для кучного выщелачивания, посредством последовательного введения в сырье первого и второго растворов для предварительной обработки в поверхностном биореакторе без перемешивания для кучного выщелачивания, в котором первый раствор имеет содержание железа более 5 г/л и рН ниже 2, а второй раствор содержит существенно более высокое количество микроорганизмов. Изобретение также относится к способам адаптации популяции микроорганизмов к применению в поверхностном биореакторе без перемешивания для кучного выщелачивания.The invention relates to a method for pretreatment of raw materials entering the surface bioreactor without mixing for heap leaching, by sequentially introducing into the raw materials the first and second solutions for pretreatment in the surface bioreactor without mixing for heap leaching, in which the first solution has an iron content of more than 5 g / l and pH below 2, and the second solution contains a significantly higher number of microorganisms. The invention also relates to methods for adapting a population of microorganisms for use in a surface bioreactor without mixing for heap leaching.
