摘要

文摘:对难选硫化金精矿高压釜氧化浸出过程进行了探讨。因此，在高压灭菌器的所有内部表面形成难以去除的沉积物(外壳)，这降低了设备的生产率。在高压灭菌器中，沉积物的相组成随截面的变化而变化，沉积物的主要成分是钾黄钾铁矾KFe3(SO4)2(OH)6。分析了矿床的形成机理，探讨了防止矿床形成的可能方法。

On the Formation of Deposits during Autoclave Oxidative Leaching of Concentrates of Refractory Sulfide Gold Ores

Abstract—The processes occurring during autoclave oxidation leaching of refractory sulfide gold ore concentrates are discussed. As a result of them, hard-to-remove deposits (crust), which decrease the productivity of the equipment, form on all internal surfaces of autoclaves. The phase composition of the deposits is shown to change from section to section in an autoclave, and the main component of the deposits is found to be potassium jarosite KFe₃(SO₄)₂(OH)₆. The mechanism of formation of deposits is analyzed and possible methods to prevent them are discussed.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
