The processing capacity of a gold concentrator in Shandong mine is 10000 t/d, and the production process of one-stage grinding + one roughing, two sweeping and one finishing is adopted. The grinding fineness is 50%-55% of -200 mesh content, the flotation concentration is 40%-45%, and the dosage of butyl xanthate used as collector is 120 (g/t). The amount of QX-3 used as foaming agent is 40 (g/t), and the field flotation recovery rate is 93.74%. Because the mixing of tailings backfill into raw ore will cause the deterioration of flotation index, this study aims to find out the influence of tailings backfill in gold ore on flotation index, and put forward reasonable suggestions, so as to provide technical guidance for the mixing of tailings backfill in the subsequent production of gold mine.
