Pilot-scale plant for processing gold ores and concentrates (optional)

摘要

Pilot plant processing of gold ores and concentrates relates to hydrometallurgy enrichment and noble metals, in particular a flow diagram of a pilot plant for processing gold ores and concentrates. The object of the utility model is to provide a compact, mobile, pilot plant, the instrumental line which allows to simulate and implement the various, for hardware design, processes refining gold ores and concentrates of different types in a continuous process due to different connection schemes associated vehicle modules. The technical result of the proposed utility model is achieved by the Pilot plant processing of gold ores and concentrates, comprising in series and / or parallel mounted downstream of and connected to each other vehicles ore grinding module flotation crushing products unit gravity separation module flotation concentrate, leaching of gold from the module residual concentrate cyanide and gold extraction module from pulps with rbtsiey, characterized in that the installation is also provided with a thickening and filtration module processing products gravio- module regrinding and flotation concentrates, concentrates module bacterial oxidation and decontamination module, wherein the crushing unit and the gravitational classifying ore beneficiation set at the beginning of the line, the initial displacement means products or products gravity module connected to the flotation, and means for moving the gravity concentrate or middlings with gravity The uniform module regrinding and modules flotation and regrinding concentrates displacement means processing products, connected with the module condensation and filtration, and the displacement means flotation tailings, flotation unit (in the case of depleted content of gold) is connected with the module neutralization, condensation module and filtering processing products, in turn, means for moving the condensed raw products or regrinding coupled to bacterial oxidation module concentrates and / or the module regrinding, and / or with the module neutralization alkalizing pulp cyanidation products sorbent regeneration, electrolysis and melting cathode deposit and bacterial oxidation module concentrates, in turn, is connected to means for moving the oxidized concentrate thickening and filtration module, and means; displacement sorbent regeneration products of electrolysis and melting cathode deposit module cyanidation alkalizing the pulp, and the latter, displacement means coupled to the cyanation product with the modulus of neutralization. The variants of the installation schemes which allow changing the flow chart of connecting equipment units by simulating connection vehicles moving products binding modules (valve, flexible hose connections, piping) on ​​the same pilot plant, to carry out testing and testing different flowsheets and processes. 4 bp f BACKGROUND illustration: 4.
