| Abstract: | Based on the study of single particle settling motion, experimental studies on floating velocities of coarse particles were conducted for manganese nodules, cobalt-rich crust, polymetallic sulfide and simulated nodules using high-speed photography, from which calculation formulas of floating velocity were derived for single particle and group of coarse particles. It is found that the calculated value is in good agreement with experimental results, indicating it can be of reference to parameter design and normal operation of vertical pipe hydraulic transportation system. |
