    Flash Flotation Flash flotation offers a unique opportunity to improve performance in many mineral processing circuits. Successes in metal recovery of the gold, lead, nickel, copper, and platinum group of metals are well documented. Every project is custom engineered with Application Driven Design for proper metallurgy. Each cell is configured to

    Sep 21, 2017 SkimAir Flash flotation cell. Flash flotation (SkimAir SK500) was also investigated by Outotec as part of the BSF upgrade. The objective was to increase the recovery of liberated coarse (+106 μm) sulphur minerals and lower the BSF tails further from 2.5% S to ≤1.5% S. The justification for flash over conventional flotation was based on the ALS mineralogy findings
