Cobalt-rich manganese deposit (CRMD) have a significant advantage of developing projects, when they can be separated the metal-bearing crust from the accompanying rocks by introducing the mineral processing. Using the mineral processing experimental data given by the Deep Ocean Minerals Association (DOMA), the authors evaluated the cost of the total system for CRMD development.<BR>We tried to elaborate an economic improvement in considering influences upon the system combination and the apatite / basalt ratio contained in basement rocks. Comparing further the respective economic evaluation, we could obtain the profit and loss curve for a promising CRMD condition.<BR>As a result, an optimized development method was proposed as follows: it was to use robotic miner for mining, gravity concentration for mineral processing and smelting and chlorine leaching process for metallurgical process in the Co : 0.41 %, Ni : 0.35 %, Mn : 14 %, Cu : 0.07 % overgrade basaltic sites.
