New Method of leaching of Copper oxide ore with High Content of carbonates using as lixiviant R - Sun

摘要

It consists of: a) applying Reagent based on nh2s03h Crystals (R - Sun) to the mineral, in the thick pile of Minerals, as well as the fine ore Pulp, agitated Tanks immediately, causing a series of simultaneous reactions; firstly decomposes the calcium carbonates. It reacts with the oxides of Copper,With carbonates of native copper and Copper leaching; (b) The Reagent reacts with the calcium carbonate, solubilizes the calcium on the State of Calcium Sulphite, remaining in the aqueous solution during the whole process.In addition to Generating two Products: CO2 and NH4OH aqueous solution form the AMMONIUM CARBONATE; AMMONIUM CARBONATE reacts with carbonates (Copper Malachite, Azurite) present in the Ore, Leaching the native Copper; (e) the product obtained by this process lixiviaci On is a Solution impregnated or Loaded, mainly containing Copper sulfate AmmoniumCopper carbonate, ammonium and calcium Sulphite
