Crushing equipment combination and investment for small gold ore processing plant

Small gold ore processing plants (typically 50-200 tons per day) require a compact, affordable, yet efficient crushing circuit. The optimal crushing equipment combination and investment for small gold ore processing plant balances capital cost, operating cost, and gold recovery. OCP Machinery, with 40 years of experience, recommends a two-stage or three-stage modular system: a small jaw crusher for primary reduction, followed by either a hammer crusher or a roll crusher for fine crushing, plus a vibrating screen. For a 100 t/d plant, the investment ranges from $45,000 to $85,000 USD depending on automation level. OCP’s recommended crushing equipment combination and investment for small gold ore processing plant includes: ZSW-380×96 vibrating feeder ($3,500), PE-400×600 jaw crusher ($12,000), PF-1007 impact crusher or 2PG400×250 roll crusher ($8,000-$15,000), and a 2YK1230 vibrating screen ($5,000). This combination produces a final product of <10mm, suitable for ball mill feeding or direct heap leaching.

In actual operation, the gold ore is fed manually or by a small loader into the jaw crusher hopper. After primary crushing to <60mm, the material is conveyed to a hammer crusher or roll crusher for secondary reduction. A screen closed circuit ensures that oversize returns to the fine crusher. OCP recently built a crushing equipment combination and investment for small gold ore processing plant in Zimbabwe: a 75 t/d plant using a PE-400×600 jaw crusher and a 2PG400×250 double roll crusher, with total equipment investment of $58,000. The plant achieved a crushing ratio of 20:1 and a product P80 of 8mm, increasing ball mill throughput by 35% compared to their previous single-stage hammer mill. OCP’s custom capability includes designing skid-mounted units for easy transport and installation. Our direct factory pricing eliminates dealer markups, saving small miners 20-30%. Environmentally, OCP offers a wet crushing option with a small settling pond to control dust without expensive baghouses.

OCP’s 40 years of experience serving artisanal and small-scale gold miners has resulted in a “Mini-Crush” series specifically designed for low headroom and limited power (diesel or single-phase electric). For a gold operation in Peru, OCP provided a crushing equipment combination and investment for small gold ore processing plant that included a diesel-powered jaw crusher and a portable trommel screen, all mounted on a single trailer, costing $42,000. The customer recovered 85% of gold with simple gravity concentration. We also offer financing options and used equipment refurbished to as-new condition.
