Introduction
How It Works: Dredging + Gold Recovery in One PassOur gold dredger uses the proven jet suction principle for sediment extraction, paired with an integrated gravity concentration system for gold recovery — all on one hull, no extra equipment needed.Step 1: Jet suction loosens and sucks raw materialA high-pressure water pump generates 0.8–1.2MPa jet flow through tungsten carbide nozzles, fluidizing sand, gravel and gold-bearing alluvial deposits from the riverbed. The 6–10 inch high-chrome dredge pump then sucks the raw slurry into the onboard processing system.Step 2: Primary screening & classificationThe slurry first passes through a vibrating screen or trommel screen that separates oversized rocks, pebbles and debris larger than 5–10mm, letting only gold-bearing fine sand and gravel enter the concentration system.Step 3: Gravity gold concentrationClassified slurry flows through our multi-stage gravity concentration system: Gold sluice box with ribbed rubber mats: Captures coarse and medium gold particles (0.5mm+) Knelson concentrator / centrifugal gold concentrator (optional upgrade): Recovers fine and ultra-fine gold particles (0.01–0.5mm) with 90%+ recovery rate Gold shaking table (optional): For final cleaning and high-purity gold concentrate production Step 4: Tailings dischargeWaste sand and water are discharged through the standard pipeline to designated stacking areas — or can be pumped directly back to the river for low-impact mining.The entire process runs continuously in one pass, meaning you dredge and recover gold simultaneously. No waiting, no re-handling, no double fuel cost.Core Advantages of Our Gold Recovery Jet Suction Dredger1. 2-in-1 Design = Lower Investment, Higher ProfitWhy buy a separate dredger and a separate gold plant when one machine does both? Our integrated design: Cuts total equipment investment by 40–50% Reduces fuel consumption by 30% (one engine powers both systems) Needs only 2–3 operators (vs. 5–6 for separate machines) Saves site space and logistics cost 2. Proven Jet Suction Technology = Zero CloggingUnlike bucket ladder dredges or suction dredges with cutter heads that frequently jam on rocks and roots, our jet suction design has no rotating parts in the water. It handles roots, twigs, plastic debris and mixed-size gravel without clogging — critical for alluvial gold mining sites where riverbeds are messy and unpredictable.3. High Gold Recovery Rate Coarse gold (>0.5mm): 95%+ recovery via sluice boxes Fine gold (0.01–0.5mm): 90%+ recovery with centrifugal concentrator upgrade Ultra-fine gold (<0.01mm): Recoverable with additional shaking table and flotation options We customize the concentration system based on your gold particle size distribution — no one-size-fits-all guesswork.4. Shallow Water Champion = Access More Gold Deposits Minimum working water depth: 0.5m Draft: only 0.45m Most alluvial gold deposits sit in shallow rivers, creeks and tributaries where large dredgers run aground. Our ultra-low draft gold dredge navigates these shallow zones with ease, reaching gold deposits that your competitors can’t access.5. Modular & Portable = Easy to RelocateAll our gold dredgers feature split modular design: Disassembles into sections that fit in 20ft / 40ft containers No oversized cargo fees for international shipping On-site assembly in 1–2 days with basic tools Can be moved between mining sites by truck or even by hand in remote areas This is a game-changer for small miners who work multiple claims or need to move seasonally.6. In-House High-Chrome Pump = Durability You Can Count OnThe dredge pump is the heart of any gold dredge. We manufacture our own pumps with 28–32% high-chrome alloy impellers and volutes, specifically designed to handle the abrasive sand and gravel typical of gold mining sites. Our pumps last 30–40% longer than standard cast iron pumps, reducing downtime and replacement costs in remote mining areas where spare parts are hard to find.Standard Technical Specifications (Gold Recovery Jet Suction Dredger) 表格Parameter6-inch Gold Dredge8-inch Gold Dredge10-inch Gold DredgeHull size (L×W×D)7×2.0×0.7m9×2.6×0.9m11×3.0×1.1mDraft0.4m0.5m0.6mTotal weight~6t~12t~20tSuction pipe diameter6 inch (150mm)8 inch (200mm)10 inch (250mm)Main pump power75kW110kW160kWJet pump power37kW55kW75kWTotal installed power~130kW~200kW~280kWDredging depth1–6m1–8m1–10mMin water depth0.5m0.6m0.7mSlurry handling capacity150–250m³/h300–450m³/h500–700m³/hGold recovery rate (coarse)90%+92%+95%+Gold recovery rate (fine, with upgrade)85%+88%+90%+Standard gold systemSluice boxSluice box + classifierSluice box + trommel + classifierDischarge distance300m500m800mComparison: Our Gold Dredge vs. Imported Brand vs. Separate Equipment 表格FeatureYuanyang 2-in-1 Gold Jet DredgeImported Brand Gold DredgeSeparate Dredger + Gold PlantTotal costMedium (best value)Very high (2–3x our price)High (40–50% more than ours)Gold recovery rate90%+ (fine gold upgrade)92–95%90–93%Clog resistanceExcellent (jet suction)Good (cutter suction)Depends on dredger typeShallow water capabilityExcellent (0.5m min)Poor (1.5m+ min)PoorTransport & setupEasy (container, 1–2 days)Difficult (oversized, weeks)Very difficult (2 machines)Operators needed2–33–45–6Fuel consumptionLowMediumHigh (two engines)Best forSmall-medium alluvial gold miningLarge-scale professional miningLarge, fixed-site operationsCore Conclusion: Our 2-in-1 gold jet suction dredger gives you nearly the same gold recovery performance as top imported brands, at a fraction of the cost, with better shallow-water access and lower operating expenses. It’s the smartest investment for small and medium-scale alluvial gold miners.Ideal Application Scenarios1. River Alluvial Gold MiningThe most popular use case. Extracts gold-bearing sand and gravel from riverbeds and recovers gold on board in one continuous process. Perfect for small to medium alluvial gold deposits across Africa (Ghana, Mali, Nigeria, DRC), Southeast Asia (Indonesia, Philippines, Myanmar) and South America.2. Creek & Tributary Gold MiningUltra-low draft allows access to narrow, shallow creeks and tributaries where large dredgers cannot go — often the richest gold deposits that big mining companies ignore.3. Beach & Coastal Placer GoldRecovers heavy minerals and fine gold from beach sands and coastal placer deposits. Optional stainless steel upgrade available for saltwater corrosion resistance.4. Gold Tailings ReprocessingRe-processes old gold mine tailings to recover fine gold that was missed by older, less efficient equipment. A low-risk, high-return way to monetize abandoned tailings ponds.5. Diamond & Heavy Mineral MiningEasily reconfigured for diamond mining, tin mining, zircon or other heavy mineral extraction — just swap the concentration modules.[IMAGE POSITION 1: Gold jet suction dredger working on a river gold mining site][IMAGE POSITION 2: Close-up of gold recovery system / sluice box with gold concentrate, or factory assembly photo]Full Customization — Tailored to Your Gold DepositEvery gold deposit is different.
