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.

Abstract

The invention discloses an ore-blending and smelting method of ocean cobalt-rich crusts, comprising an ore-blending step and a smelting step. The ore-blending step is as follows: blending ores of more than one ocean cobalt-rich crust and more than one ocean metal nucleus. The ore-blending and smelting method of ocean cobalt-rich crusts has the advantages pf further optimized process, low production cost, little energy consumption and further improved product quality and yield.

Description

technical field [0001] The invention relates to a method for smelting seabed manganese-containing polymetallic ores, in particular to a method for blending and smelting different types of seabed manganese-containing polymetallic ores. Background technique [0002] Oceanic cobalt-rich crusts and oceanic polymetallic nodules are two different polymetallic mineral resources on the seabed, rich in Mn, Fe, Cu, Co, and Ni, and therefore have become important potential metal resources for human beings. Western advanced countries such as the United States, Germany, France, and Japan, and developing countries such as China, India, and South Korea have invested a lot of money in the extraction and metallurgy research of valuable metals, and developed a variety of smelting and processing techniques, among which the smelting-leaching method is considered It is one of the most promising extraction metallurgical methods. [0003] Pyroenrichment is the first step in the smelting-leaching ...
