Abstract
Inventia se refera la un procedeu de separare a concentratelor colective de Pb-Cu, în care raportul continuturilor de Pb/Cu este mai mic sau egal 1, respectiv o pondere majora a calcopiritei în raport cu galena. Concentratul colectiv de Pb/Cu se îngroasa, se supune desorbtiei colectorilor cu sulfura de sodiu si carbune activ, se trateaza în stadiul I cu bioxid de sulf, amidon, sulfat de zinc pentru depresarea galenei, piritei si blendei continute si se floteaza partial calcopirita cu diizobutilditiofosfat sau xanat etilic. în continuare, produsul de camera se îngroasa, se supune desorbtiei colectoarelor cu sulfura de sodiu si carbune activ, se trateaza succesiv în stadiul II cu combinatia bicromat de sodiu (potasiu) - silicat de sodiu, amidon, sulfat de zinc si sulfit de sodiu pentru depresarea intensiva a galenei, piritei si blendei continute si se floteaza integral calcopirita ramasa, cu xanat etilic. Calcopirita flotata în ambele stadii se cumuleaza într-un concentrat selectiv de Cu, iar produsul de camera constituie concentratul de Pb, ce cumuleaza si zincul continut în vederea valorificarii comune.The invention relates to a process for the separation of Pb-Cu collective concentrates in which the ratio of Pb / Cu contents is less than or equal to 1, and a major proportion of calcopirite relative to galena. Collective Pb / Cu concentrate thickens, collects sodium sulphide and activated charcoal desorption, is treated in stage I with sulfur dioxide, starch, zinc sulphate for depressing the galena, pyrite and blend and partially calculates the calcopiric with diisobutyldithiophosphate or ethyl xanthate. Further, the product of the chamber is thickened, subjected to desorption of the collectors with sodium sulfide and active carbon, is treated successively at stage II with the combination of sodium dichromate (potassium) - sodium silicate, starch, zinc sulphate and sodium sulphite for the intensive depression of the galena, pyrite and blend contained, and the remaining calcopirin, with ethylene xanthate, is fully flown. The capillary floatation in both stages accumulates in a selective Cu concentrate, and the product of the chamber is the Pb concentrate, which accumulates zinc for common use.
