Abstract
A heap cryoleaching technology for gold ores was justified basing on theoretical and experimental research into physical, hydrophysical and physiochemical properties of sulfuric-chloride solution in the presence of manganese dioxide within a wide range of negative temperatures. This geotechnology enables year-round heap leaching of gold in conditions of the permafrost zone through controlling concentration of the electrolyte-cryoprotective agent – sulphuric acid.
