Abstract

The authors assess prospects for recycling of carbonate–fluorite ore processing waste in the Voznesensky ore district in the Primorski Krai. The main factors that can influence processing of slime are determined. The flotation-based recoverability of fluorite from low-grade (11.56–13.12% CaF2) and fine-dispersion secondary material containing up to 88% of particles less than 10  \(\mu\) m is demonstrated. A rational process flow sheet to produce concentrates with CaF2 content more than 93% mass at fluorite recovery to 52% is substantiated and proposed. Processibility of samples having different degrees of dispersion is compared. The use of electrochemically pretreated water in the process increases recovery of fluorite in concentrate by 3.6–4.7%. The variants of joint processing of charge material from different areas of the manmade deposit are discussed.
