Control systems of sintering processes in rotary tubular kilns with using of thermovisors scanning

Article preview

The article considers the role of the lining in the tubular rotary kilns used for heat treatment processes of  raw material in the metallurgical, chemical and other fields of industries. The method of selecting a new design thermal insulation elements, ensuring reduction of heat loss to the environment and  more  accurately to provide  the required thermal  processing mode through simulation can be used with  ANSYS FLUENT software package. A system of monitoring the state of the lining with a thermal imager and control system that provides consistency lining without stopping the  operating kiln  has  been  developed.

Development of an environmentally safe gold extraction method from refractory ores using sodium thiosulfate as an extractant

Article preview

The article presents the results of a mathematical model development for the process of gold leaching from gold-containing ores and concentrates. A mathematical model has been developed by analyzing the chemistry of reactions and mass transfer processes. On the base of a kinetic extraction model and a hydrodynamic complete mixing model a mathematical model of thiosulfate leaching process in various types batch reactors, complete mixing flow process vessels and complete mixing reactor columns with different numbers of vessels in a column has been developed. The effect of the number of reactors in a column has been investigated and optimal segmentation conditions have been found. Based on the investigation of the process using the mathematical model a control system structure has been designed to provide maximum conversion at the exit area of a reactor column.

Article preview

A kinetic gold leaching model, based on the well-known shrinking core model, is presented in this work. The model considers the effects of internal diffusion, surface reaction and unreacted amount of gold in the concentrate particle during leaching. The model parameters are estimated by minimization of mismatching between experimental data and results of numerical computation of kinetic model made by using ReactOp  software.

Article preview

The method of recovery the refractory sulfide ores with the aid of pressure oxidation was examined. The basic processes of oxidation was discovered and the mathematical description of  the process of sulfide oxidation in a heterogeneous system, the  liquid – solid, was suggested. The ReactOp allowed to solve inverse   problem – determination of kinetic parameters (E = 112 kJ/mol, ln(K) = 20 m/s) from the experimental data. On the basis of defined parameters is made and investigated the cascade of continuous stirred-tank reactors.
