Abstract

The invention discloses a novel method for simultaneously treating submarine cobalt manganese oxide resources and poly-metallic sulfides. The main technological processes include crushing, ore-proportioning and fine-grinding, sulfuric acid leaching and liquid-solid separation. The novel method comprises the following key steps: respectively crushing the submarine cobalt manganese oxides and the poly-metallic sulfides; proportioning the two crushed minerals according to certain ratio; performing fine grinding on the proportioned minerals; performing sulfuric acid leaching on the finely-ground minerals; after the completion of the leaching, performing liquid-solid separation to obtain a solution containing nickel, cobalt, copper, manganese and iron; performing conventional metallurgical treatment on a leaching solution to respectively obtain nickel, cobalt, copper and manganese products. The acid leaching process is performed under ordinary pressure, no additive is additionally added, and the environmental pollution problems of CO, SO2 and ammonia volatilization and the like existing in an existing submarine cobalt manganese oxide wet treatment process are solved. Meanwhile, the effect of treating submarine mineral resources with different natures through one process is realized. The novel method has the advantages of environmental protection, collaborative development and utilization of the various submarine resources with the different natures and high comprehensive utilitarian rate of the resources.

Description

technical field [0001] The invention belongs to the technical field of non-ferrous metal metallurgy, and relates to a new process for simultaneously processing seabed manganese-cobalt oxide resources and polymetallic sulfides. Background technique [0002] The seabed of the ocean is rich in important strategic resources such as metal minerals, which is an inevitable choice for the development of global society and the sustainable utilization of resources. The proven metal minerals are polymetallic nodules, cobalt-rich crusts and other seabed cobalt-manganese oxides, polymetallic Sulfide etc. [0003] The amount of manganese at the bottom of the Pacific Ocean is 470 times that of the proven land manganese ore. Moreover, according to J.L.Mero’s estimation, the nodule reserves on the surface of the entire ocean floor amount to 3 trillion tons, of which 1.7 trillion tons are stored in the Pacific Ocean, containing about 14.6 billion tons of nickel, 7.7 billion tons of copper, 9...
