The study analyzes the practice of fine wet screening of slurry solids in ore processing for the last few years. The current urgency of the problem of replacing hydraulic density-based classification of finely ground ores with separation by geometric size is noted. The practice of processing low-grade finely disseminated ores shows that a significant proportion of mineral losses is due to …
