Study on the Influence of Underground Filling Body on Flotation Index of Beneficiation in Gold Mine

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