Jugger boats, also known as gold dredges, are integrated waterborne factories that combine mining and ore processing operations. They are sand gold mining equipment, encompassing systems such as excavation, ore selection, water supply, waste ore and tailings disposal, deck machinery, hull, power supports, and power sources. In terms of ore processing technology, gold dredges are categorized into fixed sluices, belt conveyer sluices, vibratory sluices, self-discharging fixed sluices, water jacket centrifuges, circular jigging machines, and others. In terms of excavation capacity, they range from 15 to 300 liters in various models. Sand gold is primarily found in the mixed sediment layer at the bottom of riverbeds, and it undergoes several processes to separate sand and gold. The primary tool for gold panning is the gold dredge, which has been designed for excellence. Larger dredges are equipped with automatic sand gold cleaning systems, achieving purity levels up to 80%.
