roject Background
A river placer gold mining area in Ghana has long relied on manual gold panning. Although the gold content of the ore belt reaches 50 grams per ton, the efficiency of manual screening is low—with a daily ore processing volume of less than 50 cubic meters and a gold recovery rate of only 40%. Local mining enterprises were in urgent need of automated equipment to improve production capacity, and Huayao's HY-150 Bucket Chain Gold Dredger won the bid with its advantages of "deep excavation + high recovery".
Core Advantages of the Equipment
1. Efficient Excavation Adapted to River Working Conditions: 120 sets of manganese steel bucket chains operate in linkage, achieving a daily ore processing volume of 3,000 cubic meters. The excavation depth covers the 2-15 meter river ore layer, which is 60 times more efficient than manual work.
2. Step-by-Step Gold Recovery System: It sequentially performs impurity removal via a trommel screen, rough separation through a jigging chute, and fine separation with a centrifugal concentrator. The recovery rate of gold particles larger than 0.05mm reaches 92%, 52% higher than that of local equipment.
3. Low Consumption & Easy Maintenance: Equipped with an energy-saving diesel power system, it consumes only 8 liters of fuel per 100 cubic meters of ore processed; the modular component design allows local workers to complete daily maintenance after simple training.
Project Outcomes
Two months after the equipment was put into use, it has processed a total of 180,000 cubic meters of ore and recovered 90 kilograms of gold, helping the mining enterprise achieve a stable daily gold output of 1.5 kilograms. The mine manager commented: "Huayao's gold dredger has taken us from 'manual gold searching' to 'mechanical gold mining', shortening the payback period by 4 months compared to expectations."
