Don't let heavy metals slip away with wastewater anymore! Our spiral chute uses a "roller coaster-style" 9-ring three-dimensional spiral to amplify the density difference by 300 times, achieving accurate separation of gold, tungsten, and tin ores in 0.5 seconds. Ore recovery rate ↑30%, tailings directly reduced by half! No reagents, no noise, environmental assessment passed with ease. Modular assembly, installation in 3 hours, and can be operated by a single person. Corrosion-resistant fiberglass + diamond-abrasive lining, no maintenance for 3 years. On-site video: With the same 10 tons of raw ore, the traditional shaking table only recovered 3.8kg of gold, while the spiral chute directly recovered 5.1kg, earning an extra profit of ¥43,200 per day!
