Product Name: Manual Eco-Prospector: Integrated Gold & Gemstone Sluice SystemProduct Overview:The Manual Eco-Prospector is a portable, gravity-fed classification and recovery sluice designed specifically for eco-conscious prospectors and gemstone hunters. Engineered for areas where motorized equipment is restricted, this high-efficiency system relies entirely on manual fluid dynamics to separate high-density minerals (like gold) and lower-density precious stones (like emeralds and sapphires) from raw river gravels.Key Features & Technical Specifications:Dual-Recovery Sluice Box:A multi-stage anodized aluminum channel optimized for dual-density separation. The upper section features heavy-duty ribbed rubber matting designed to immediately trap high-specific-gravity gold particles. The secondary section utilizes low-profile expanded metal riffles over miners' moss, creating controlled micro-vortices that catch emeralds and crystals without washing them away.High-Contrast Inspection Deck:An extended, flat-bottomed plucking zone lined with a high-gloss, ultra-white polymer coating. This creates an optical contrast zone under shallow, laminar water flow, allowing the operator to instantly spot and hand-pick vibrant green emeralds, beryls, or minerals with a pair of tweezers as the waste sand passes through.Gravity-Fed Grizzly Classifier:An integrated angled classifier screen positioned at the hopper head. It automatically rejects oversized rocks (10mm+) to protect the recovery See more
