Abstract

The results of studies on flotation slurry heating effect upon bulk copper-lead-zinc concentrate selective separation with application of modified mixed aerofloat in comparison with base butyl aerofloat are presented. Modified mixed aerofloat is a mixture of butyl aerofloat with fusel oil in a 1 : 3 ratio. Experiments proved that modified mixed aerofloat consumption, if compared with butyl aerofloat, is decreased by 10 g/t. With that, base metals recovery into bulk concentrate is increased by 1.5–3 %. The results of studies showed, that in bulk copper-lead-zinc concentrate selective separation with application of modified mixed aerofloat, flotation slurry heating is required only in copper concentrate separation cycle. At the temperature of +60 °С, copper concentrate was produced with copper mass fraction of 28.9 %, recovery being 68.5 %. With temperature increase, copper recovery into copper concentrate is increased by 13.7 % in open flotation circuit and by 6.1 % in closed flotation circuit. Increased temperature also permits to eliminate sodium sulfide from desorption process.
