Substantiation of the process of transition of noble metals in solution when dissolved copper-nickel anodes on the basis оf the diagrams Purbe

Article preview

The increasing need for precious metals causes necessity of development of secondary metallurgy. Now, the important condition of processing of waste of the radio-electronic industry is the fullest extraction of precious metals and reduction of weight of the rests. Assumptions of possible options of behavior of precious metals depending on conditions of conducting process of electrolysis on the basis of charts of Purbe are given.

Character determination of fusion mode оf sulphidic material in the gas-jet rotation devise

Article preview

By working out of new technologies for fusion of sulphidic concentrates on matte and hardware registration to them special attention it is necessary to give possibilities of management of oxidation degree of malt in a reactionary zone and uniformity of oxidation process. In this connection development of the oxidation theory and behavior of sulfides in malt is of great importance for designing of fusion devices of sulphidic concentrates and revealing of management possibility of them.

Improvement development of technology for processing electronic scrap concentrates

Article preview

The question of electronic scrap processing concentrates of varying composition. During  the oxidative electrolysis smelting electronic scrap it became clear that the electrolyte composition is variable. And this complicates the whole technology of purification of the electrolyte, making it cumbersome and not profitable from an economic perspective. To improve the technology was considered by the option of separate processing of iron-nickel cobalt and copper silver concentrates.

Processes of oxidation of impurities of metal concentrate of radio-electronic scrap

Article preview

The study was carried out in order to find technological conditions that allow anodic dissolution of metal concentrate of radio-electronic scrap without difficulties caused by anode passivation. The thermodynamic probability of sufficiently complete oxidation of impurities included in the metal concentrate was established. The composition of refining slag allowing to bind oxidized impurities in slag is selected. Time dependence of oxidation of impurities by air due to application of radial-axial tuyere is shown. It is indicated that for 15min of blowing it is possible to prepare the metal-concentrate alloy for successful anodic dissolution in sulfuric acid electrolyte.
