Abstract

Изобретение относится к горно-металлургической промышленности и может быть использовано при кучном выщелачивании различных металлов из руд. Целью настоящего изобретения является повышение эффективности выщелачивания за счет предотвращения образования или разрушения антифильтрационных слоев внутри штабеля КВ, а также обеспечение воздействия на нетронутые области штабеля при проникновении технологических растворов в целях восстановления или обеспечения оптимальной фильтрационной способности массива выщелачиваемых руд и освобождения для растворов золота, заключенного в рудах зоны кольматации. Для этого предусмотрено введение в них специальных устройств, преимущественно в виде роботов-червяков (так называемых "электронных червей, электрических червей, умных червей или цифровых червей") или иных видов миниатюрных (отвечающих требованиям) устройств, предназначенных для передвижения в штабеле КВ, преимущественно в местах образования антифильтрационных слоев, с образованием каналов до восстановления их оптимальной проницаемости.The invention relates to the mining and metallurgical industry and can be used for heap leaching of various metals from ores. The aim of the present invention is to increase the leaching efficiency by preventing the formation or destruction of anti-filtration layers inside the KV stack, as well as to provide exposure to intact areas of the stack during the penetration of technological solutions in order to restore or ensure the optimal filtration capacity of the mass of leached ores and release the gold contained in ores of the colmatation zone. For this, it is envisaged to introduce special devices into them, mainly in the form of robotic worms (the so-called "electronic worms, electric worms, smart worms or digital worms") or other types of miniature (meeting the requirements) devices intended for movement in a KV stack, mainly in places of formation of anti-filtration layers, with the formation of channels until their optimal permeability is restored.
