Способ по п.1, отличающийся тем, что дробленую крепкую руду крупностью менее 20 мм, перед формированием штабеля кучного выщелачивания золота, подвергают замораживанию при температуре ниже -10°C с последующим ее оттаиванием до температуры более +5°C.3. Способ по п.1, отличающийся тем, что после проведения кучного криовыщелачивания золота, штабель кучного выщелачивания золота подвергают естественному промерзанию-оттаиванию с проведением повторной стадии кучного криовыщелачивания золота.4. Технология для криовыщелачивания золотосодержащего сырья, содержащая последовательно расположенные отделение дробления руды, отделение подготовки выщелачивающих растворов, штабель кучного выщелачивания золота, отделение восстановления золота, отличающаяся тем, что технология дополнительно снабжена отделением криодезинтеграции руды, установленны1. The method of heap cryo-leaching of gold-bearing raw materials, including the separation of ore crushing, adding regenerated manganese dioxide to the crushed ore, heap sulfuric acid-chloride leaching to obtain a gold precipitate, characterized in that sulfuric acid-chloride leaching of gold-containing raw materials in the presence of negative manganese dioxide and conducting dioxide ore stack temperatures from +20 to -30 ° C with a weight content of cryoprotectant electrolyte - sulfuric acid more than 10.5%, and weight soda The holding of the cryoprotectant-sulfuric acid electrolyte is regulated taking into account the ore porosity in the stack, as well as the geotechnological parameters of the leaching solution - temperature, dynamic viscosity, density and filtration coefficient. 2. The method according to claim 1, characterized in that the crushed strong ore with a particle size of less than 20 mm, before forming a stack of heap leaching of gold, is subjected to freezing at a temperature below -10 ° C, followed by thawing to a temperature of more than + 5 ° C. 3. The method according to claim 1, characterized in that after carrying out heap cryo-leaching of gold, the stack of heap leaching of gold is subjected to natural freezing-thawing with a repeated stage of heap cryo-leaching of gold. A technology for the cryo-leaching of gold-bearing raw materials, containing a sequentially located ore crushing compartment, a leach solution preparation department, a heap leach stack of gold, a gold recovery department, characterized in that the technology is additionally equipped with an ore cryosintegration department
