Evaluación de la flotación de lodos finos de carbón usando análisis reléase

Abstract

Performance of flotation when processing a refuse tailing fine coal slurry from a Colombian coal cleaning
plant was studied using release analysis to evaluate the potential cleaning in terms of both, low ash and
high recovery. Results from release analysis showed, that this was a good estimate for obtaining ideal
flotation data, as well as exploring the feasibility of cleaning this material.
The results showed that the best combination of collector–frother was diesel oil-MIBC, producing recoveries
on the order of 65%, with cumulative ash value less than 10%. It was also tend that the type of
frother significantly affected the behavior of a refuse tailing fine coal slurry in a mechanical flotation cell.
