Изобретение относитс к горно-добывающей промышленности, в частности к геотехнологическим способам переработки руд, и может быть использовано в области кучного и подземного выщелачивани руд цветных металлов.The invention relates to the mining industry, in particular to geotechnological methods of processing ores, and can be used in the field of heap and underground leaching of non-ferrous metal ores.
Целью изобретени вл етс ускорение процесса вьщелачивани и снижение расхода реагентов.The aim of the invention is to accelerate the leaching process and reduce the consumption of reagents.
Сущность способа заключаетс в следующем.The essence of the method is as follows.
На объект выщелачивани (отвал руды или участок подземного вьщелачивани ) подают водные растворы серной кислоты такой концентрации, чтобы рН растворов был 1,0-1,5. В выщелачивающий раствор добавл ют фениламин в количестве 0,1-0,2 г/л. Фениламин (C Hj NHj) в растворе взаимодействуетSulfuric acid aqueous solutions of a concentration such that the pH of the solutions is 1.0-1.5 are fed to the leaching facility (ore dump or underground alcalisation site). Phenylamine is added to the leach solution in an amount of 0.1-0.2 g / l. Phenylamine (C Hj NHj) in solution interacts
