Tiivistelmä
The aim of this master's thesis is to develop a programmed part of monitoring system for the particle size distribution of red mud slurry on the case of OJSC UAZ RUSAL's red mud.
In the course of the work, a literature review and the analysis of existing research on the topic were conducted to confirm the relevance of the master’s thesis. In particular, the following aspects of the special and practical parts were touched upon: the study of the red mud thickening process, the study of the flocculation process and kinetics, the application of the population balance. A laboratory study of the flocculation of red mud slurry was carried out on a sample obtained from the production of OJSC UAZ RUSAL in 2020. The outcome of the practical part is the implementation of the software code of the monitoring system and its visual component. The economic part considers the feasibility of implementing a monitoring system at OJSC UAZ RUSAL.
