- Abstract
The technology of flotation processing of slags of the Copper Plant, both stored in the slag dump and generated in the course of its current activity, has been proposed. Variants of autonomous processing of slags of various types, as well as their mixtures in different proportions, are considered. The technology development was based on a deep study of the material composition of slags. The results of X-ray microprobe studies of slag samples showed that the main mineral phases that make up their composition are magnetite and various silicates. The laboratory studies of fractivity and grindability have shown that dump slags, in accordance with the accepted classification, are difficult to crush and difficult to grind. Based on the results obtained, an option was selected that provides for two stages of medium crushing in cone crushers and one stage for fine crushing in a high-pressure roller crusher. Further grinding occurs in two stages with obtaining a product containing 70% of the control class of size -0.045 mm, and the material is fed to flotation.
