| 简介 |
The invention relates to mining and may be used in heap leaching of rare, radioactive and noble metals from ores, tailings and concentrates. Technical result of the invention is the diffusion lu reliability of base during long operation of. -, That in the base for heap leaching of ores, tailings and concentrates, including layers of hydro of insulating material and protective-drainage layers, located above and under hydro insulating layers, protective-drainage layer, arranged under hydro insulating layers, is made from mineral hydro filnogo sorbent with positively charged surface of mineral skeleton. In heap leaching of ores of noble metals cyanide as sorbent is natural clinoptilolite, treated successively sulfuric acid and iron sulphate solution. For diffusion condensate adsorption properties and protection lower hydro insulating layer from damage natural zeolites preliminarily ground to powder-like state. |
