Product Specification
Rock gold (hard rock gold) processing is a systematic beneficiation process designed to extract gold from gold-bearing vein ores. The complete production flow generally includes crushing, grinding, gravity separation, flotation, leaching (CIL/CIP), and smelting, to achieve efficient gold recovery.
1. Crushing & Screening Stage Raw rock gold ore is first fed into a jaw crusher for primary crushing, then sent to a cone crusher or impact crusher for secondary and fine crushing. After crushing, the ore is screened by a vibrating screen. Qualified fine ore enters the next stage, while oversized particles are returned for re-crushing to form a closed-circuit crushing system.
2. Grinding & Classification Stage Crushed ore is sent to a ball mill for wet grinding with water. A spiral classifier or hydrocyclone is used to control particle size. Qualified ore pulp enters the separation process; unqualified coarse particles return to the ball mill for re-grinding.
3. Gravity Separation Stage Gravity separation is the most economical and widely used method for rock gold. Ore pulp passes through shaking tables, spiral chutes, centrifugal concentrators, or gold centrifuges to separate heavy gold concentrate from gangue based on density difference. This step quickly recovers coarse gold and reduces the load of subsequent processes.
4. Flotation Stage For finely disseminated and sulfide-associated gold ore, flotation is applied. Reagents (collectors, frothers, modifiers) are added to the pulp to make gold particles attach to air bubbles. The froth containing gold is scraped out to obtain gold concentrate, achieving high-selectivity separation.
