Abstract
There is provided a dredge vehicle supporting a dredge assembly for collecting ore particles from the ocean floor. The dredge assembly includes several nozzles extending forwardly of the supports for the vehicle, pump means for developing a suction flow into and through the nozzles and a screen to separate the ore particles from most of the water before feeding the ore into, e.g., an airlift system leading to a surface vessel. Preferably, an intake of clear water from above the vehicle is used to carry the ore to and up the airlift system. Advantageously, the water flows straight through the system and exhausts from the rear of the vehicle, and mud is cleared from the ore before bringing the ore to the surface.
