This article is dedicated to the comparative analysis of capital and operatiо nal costs of project of construction of the concentrating plan. Implementation of the technology of coarse crushing on the Lomonosov GOK will not only provide a stable processing of ore, but also improve the productivity of the entire projected concentrator plant.
In the given work research of material structure of a radio-electronic breakage is conducted. Concentrates with different mineralogical composition selectively obtained. A study on the separate processing of concentrates is conducted in order to enhance extraction of precious metals.
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.
In the given work research of material structure of a radio-electronic breakage is conducted. Concentrates of various structure are received selectively A study of the separate processing of copper-silver and iron-nickel cobalt concentrates is conducted.
In the given work assessment of raw materials is conducted. Concentrates with different mineralogical composition selectively obtained. A study on the separate processing of concentrates is conducted in order to enhance extraction of noble metals.
The article reflects the main aspects of determining the dissolution potentials of copper- and nickel-based alloys containing precious metals in laboratory conditions and the choice of electrolyte for their dissolution. The composition of the investigated anode, graphs of dependence of the obtained potentials on time and voltage are given. The influence of some impurities on the process is explained. The conclusion about the rationality of using hydrochloric acid electrolyte is made.
