Method for leaching Copper concentrates at Ambient pressure and temperature by the formation of a gel in a sulfate chloride reagent

摘要

Chemical Process in the presence of a Concentrated solution of sulfates and CHLORIDES, leaching of Copper Concentrates, characterized by the formation of a Paste of high Chemical reactivity that contains ions of high concentration in the liquid phase of the paste, which After a time, React with the Copper Minerals, forming a series of soluble saltsWhich are subsequently extracted by a simple washing. To carry out this procedure uses a mixing device which is capable of Handling High viscosity Liquids.The total mixing time is on the Order of 5 minutes, after which the Pulp is poured into a rectangular Mold, which can have several hundred metres per Side, touching, for its size, a leaching Heap or pit of solar Evaporation and leave the rest to breathe, This is to provide the Oxygen required for the reactions.During the rest time, water was added intermittently with sulfuric acid to replace the consumption of this Reagent for reactions that occur during Aeration, until virtually the end reactions. The results of this treatment is a very resistant Dry Mass containing the extracted in the form of Copper sulfate and chloride Salts.
