Simultaneous leaching of zinc sulfide concentrates and manganese ores and simultaneous electrloysis of ainc and MnO 2 can combine the production of two products.
In 1．0～3．0 mol／LHCl solutions，the simultaneous leaching of ocean manganese noduleand zinc sulfide concentrate was investigated．The leaching conditions include the ratio be-tween the manganese nodule and zinc concentrate，the initial HCl concentration in the leach-ing solution，the leaching temperature，and the leaching time.
In this paper,a hydrometallurgical process for the treatment of zinc ore with high iron content is studied,The process mainly consists of three steps:simultaneous leach of zinc sulfide concentrate and pyrolusite,neutralization of solution by zinc oxide ore and two-stage electrolysis of Zn and MnO2.Experimental results show that the hydrometallurgical method proposed in this paper for treatment of zinc ore with high iron content is feasible technologically.
The electrogenerative simultaneously leaching process of sulfide minerals and manganese dioxide is investigated by introduction of the principle of electrical power generation.
The leaching solution of NaCl-FeCl_(3)-HCl system may be used repeatedly because Fe~(2+)becomes Fe~(3+) in solution by the H_(2)O_(2) oxidation,and Ag,Bi may be leached simultaneously.
in neutralization process of the mother liquor after copper sulfate crystallization Fe can be precipitated and its separation efficiency reaches more than 99% at pH=2. With the difference of [Cu] T/[As] T ratio and pH, the different shape copper arsenate: CuHAsO 4, Cu 2AsO 4OH and Cu 5H 2(AsO 4) 4 can be formed.
In order to enhance the electrogenerative leaching rate of chalcopyrite concentrate reasonably, the principle of generative process was applied to simultaneous leaching of chalcopyrite concentrate and MnO2.
A fast and simple procedure is presented for the simultaneous leaching of butyl (mono, di and tributyl) and phenyl organotin species from sediment samples.
The zinc sulfide concentrate and pyrolusite were leached with dilute sulfuric acid under ordinary pressure simultaneously. The leaching solution after purification was electrolysed. Metal zinc on the cathode and Υ-MnO_2 on the anode were produced. A fully hydrometallurgical process for treating zinc sulfide concentrate was developed.
The new technology of extraction of zinc and manganese dioxide from zinc sulphide concentrate and manganese ores can combine the separate processes of production of two kinds of product,so some shortcomings can be overcome and an effective way to strengthen the production of elctrolytic zinc and manganese dioxide is found.According to the results of test,this paper discusses the knetie factors in the simultaneous leaching processes of zinc sulpide concentrate and manganese ores,providing the basis for stren...
When we adopt extraction of whole seeds to Chinese tallow tree with solvent, some stillingia sebifera was extracted from it while the tallow tree was receiving the technology of expunging white hull so that the extra ctiou replaced original separating and pressing technology of stripping white hull in a mechanic way.It can not only simplify technology but can also raise the quality of stillingia sebifera. When we adopted the No 6 solvent and soaked, the efficiency of extracted stillingia sebifera may amount...
