Embodiment Construction
[0025] A kind of ore blending and smelting method of oceanic cobalt-rich crust of the present invention, its technological process is as follows figure 1 shown, including the following steps:
[0026] 1. Ore blending: First, select oceanic cobalt-rich crusts and oceanic polymetallic nodules with four different compositions as shown in Table 1 as raw material ores, and then add oceanic cobalt-rich crusts into oceanic cobalt-rich crusts according to the ore blending ratio in Table 2. The metal nodules are blended, and the properties of the furnace pellets of each mixed raw material ore after blending are shown in Table 3.
[0027] Table 1: Chemical composition of oceanic cobalt-rich crusts and oceanic polymetallic nodules
[0028]
[0029] Note: Oceanic cobalt-rich crusts and oceanic polymetallic nodules are provided by the Oceanographic Association. DY95-9, DY105-11, DY105-15, and DY105-13 under the name column in Table 1 above represent exploration sampling voyages, and R ...
