500 TPH Gold Mining Washing Plant OEM Factory Minimum Order

The Cost of Inefficient Gold Recovery at Scale

Jou 500 TPH operation faces three critical challenges that directly impact your bottom line. Eerstens, conventional washing plants lose 812% of recoverable gold in fines below 75 mikrons, representing $2.7M$4.1M in annual losses at current gold prices for a plant running 8,000 ure per jaar. Tweedens, unplanned downtime from clogged screens and worn slurry pumps costs your operation $12,000$18,000 per uur in verlore produksie. Derde, inconsistent feed material—from highclay laterites to weathered conglomerates—forces your team to constantly adjust wash water pressure and screen angles, vermindering van deurset deur 1525% during material transitions.

Can your current washing plant handle 500 TPH of variable feed without sacrificing recovery rates? Are you spending more on maintenance than the equipment is worth? The answer lies in engineered solutions designed for continuous, highvolume gold recovery.

Produk Oorsig: Die 500 TPH Gold Wassaanleg

Dit is 'n modulêre, skidmounted rotary trommel washing system engineered for alluvial and weathered hardrock gold deposits. The plant integrates three core processes: highpressure washing, vertoning, and slurry concentration.

Operasionele werkvloei:
1. Voer Hopper & Grizzly: Afloopmyn materiaal (tot 600 mm) is fed via dump truck or conveyor into a vibrating grizzly feeder with 150mm bar spacing. Oormaat (+150mm) word verwerp; undersize enters the trommel.
2. Rotary Trommel Washing: A 2.4m diameter x 8.0m long trommel rotates at 812 RPM. Internal lifters and highpressure water jets (1215 kroeg) break down clay agglomerates and wash goldbearing fines through 6mm screen panels.
3. Concentration Circuit: Trommel undersize (6mm) flows to a multistage jigging and sluicing system. Primary jigs recover coarse gold (+300 mikrons); secondary spirals and centrifugal concentrators capture fine gold (50300 mikrons).
4. Uitskotbestuur: Washed oversize (+6mm) is conveyed to a stockpile or backfill area. Slurry from concentration passes through a hydrocyclone for water recovery (8590% recycle rate).

Toepassingsomvang: Alluviale goudafsettings, verweerde saproliet, and oxidized ores with clay content up to 40%. Not suitable for primary hardrock ores requiring crushing and grinding circuits.

Toepassingsscenario's

Alluvial Gold Mine in West Africa

Uitdaging: A 500 TPH operation in Ghana faced 35% klei-inhoud in voer, causing screen blinding every 4 hours and reducing throughput to 380 TPH. Gold recovery dropped to 72% due to fines loss.
Oplossing: Installed our 500 TPH plant with highpressure wash system (15 kroeg) and dualstage jigs. Added a clay dispersant dosing system (50 dpm) to improve fines liberation.
Resultate: Deurset gestabiliseer op 500 TPH met 94% beskikbaarheid. Goudherwinning het toegeneem tot 91%. Annual production rose from 18,000 oz aan 24,500 oz, generating $9.8M additional revenue at $1,800/oz.

Weathered Saprolite Operation in South America

Uitdaging: A Brazilian miner processed saprolite with variable gold distribution—coarse gold in quartz veins and fine gold in clay matrix. Singlestage sluicing lost 40% van fyn goud.
Oplossing: Deployed our plant with 6mm trommel screens and centrifugal concentrators (Falcontype) as secondary recovery. Installed online gold analyzer for realtime grade monitoring.
Resultate: Fine gold recovery improved from 55% aan 82%. Total recovery reached 93%. Payback period on equipment was 8 months based on additional gold capture.

River Terrace Deposit in Southeast Asia

Uitdaging: An Indonesian operation processed 500 TPH of river terrace gravels with high silt content (20%). Conventional plants required daily cleaning of settling ponds.
Oplossing: Our plant included a hydrocyclone desander (200 TPH kapasiteit) and a belt filter press for tailings dewatering. Water recycle rate reached 92%.
Resultate: Waterverbruik het gedaal vanaf 1,500 m³/dag tot 400 m³/dag. Pond cleaning frequency reduced from weekly to quarterly. Operating costs decreased by $180,000 jaarliks.

Gereelde vrae

V: What is the minimum order quantity for OEM factory direct purchase?
A: The minimum order is one complete 500 TPH gold washing plant. We do not sell components separately unless part of a service agreement. Volume discounts apply for orders of 3 or more units.

V: Kan hierdie plant voer met klei-inhoud hierbo hanteer 40%?
A: Ja, maar met wysigings. Vir klei-inhoud hierbo 40%, we recommend adding a prewet conveyor (bykomende $95,000) and increasing wash water pressure to 18 kroeg. Our field data shows 92% herstel by 45% clay content with these additions.
