AI Technical Summary
Existing technologies are insufficient for the efficient separation and recovery of low-grade, complex granite porphyry lepidolite deposits, especially fine-grained and heavily muddy minerals, leading to deterioration in flotation selectivity and separation efficiency, making it difficult to achieve efficient recovery.
A combined process of high-gradient magnetic separation pretreatment and superconducting strong magnetic separation posttreatment is adopted. Through multi-step weak magnetic separation and desliming treatment, combined with flotation and scavenging, the full-size recovery of lepidolite ore is achieved. Taking advantage of the weak magnetic characteristics of lepidolite, impurities are removed first and then the target minerals are enriched. Fine mud is then treated to improve the separation effect.
This method achieves efficient recovery of low-grade lithium mica ore, improves concentrate recovery rate and separation effect, and ensures full-scale recovery and comprehensive utilization of lithium mica ore. The method is simple, economical and feasible, and suitable for industrial application.
