Review articleA systematic review of sustainable gold extraction
2022年3月1日 Depending on the mineralogy properties of the ore, physical separation can occur at crushing sizes through optical sorting, dense media separation (DMS), jigging and screening, or at fine crushing and grinding sizes by gravity separation and froth

Gold Gravity Separation - JXSC Mineral
Gravity separation is used to assist gold extraction. In the grinding and classification circuit, jig, spiral chute, and shaking table are used to recover the easily dissociated coarse-grained gold first, so as to create better
