Physical property-based screening of polyurethane foam for gold enrichment from rock gold ores

Year: 2026

Type: article

Abstract: . The U-PUF screened by the optimal parameters showed good consistency between the determined values and the certified values for 26 gold ore reference materials, and the determined values for actual rock gold ore samples were not significantly different from those obtained by the activated carbon enrichment method and fire assay. The screening standard for U-PUF physical properties established in this study resolves the dilemma of material selection in gold enrichment for batch geological samples, and provides theoretical support and technical specifications for the standardized application of U-PUF.
