The Lifting Installation of Manganese Nodules and Pump Test Кб. Comparing the tests research and economic technology of slurry pump, cleaning pump, jet pump and air lifting, slurry pump is selected as the lifting method of pilot mining testing ofIn the one way test, the nodules transport directly to a separator with pressure regulation via the feeder, the pump and pipe. Prior to the development of advanced technology mining equipment, freeing manganese from open pit rock beds required a lot more manpower and time. But compact mining equipment and its advanced technology allows manganese miners to produce far more of the valuable ore than was possible even a few decades ago. polymetallic nodules mining for a sustained development of the resource. 2. Economic considerations Increasing awareness of the distribution and potential of deep-sea minerals such as the ferro-manganese nodules and crusts (Cronan, ; Rona, ) has kept the world’s interest in these. Manganese nodules, Since research and development works were initiated to identify the best ocean bed nodule deposits, establishing mining and process route by prospective mining consortia comprised of federal and private companies from the UK, United States, Germany, Belgium, Netherlands, Italy, Japan, France, Soviet Union, India, and.

The recent and renewed interest in deep-sea mining relates to the decrease of ore grades of known land-based deposits, the increasing costs in land-based mining, as well as rising metal prices, and an increased demand for strategic metals. This study examines the economic requirements for future commercial mining projects focusing on manganese nodules.   One mining operation as described in this paper would produce × 10 3 t of nickel, × 10 3 t of copper and × 10 3 t of cobalt annually, representing approximately per cent, per cent and per cent of their respective markets. Because manganese is the most abundant constituent metal in the polymetallic nodules, it is important to understand the market dynamics.
