Embodiment 1
[0036] The main content of raw material manganese ore is shown in Table 1:
[0037] Table 1
[0038] Content (weight%)
[0039] Among them, A is the Tongling block, B is the Tongling block, C is the South African block, and D is the Indian powder. Manganese ore with the following weight ratio: 30% of A, 20% of B, 30% of C, and 20% of D are configured into mixed ore, and the Mn content in the obtained mixed ore is 17.5%, and the Fe content is 35.7%. These four kinds of manganese ores are processed into 20-40mm particle size.
[0040] And according to CaO / SiO 2 =0.35, then it is necessary to add 2.43Kg of quicklime containing 90% CaO to 100Kg of mixed ore to obtain a mixture. The particle size of quicklime is 3-10mm.
[0041] The coke is first-grade coke (ash content 12-12.5), and the particle size is processed to 25-50mm.
[0042] 1350Kg of the above-mentioned mixture and 450Kg of coke are added into the reaction furnace of the present invention. The oxygen-cont...

[0068] Among them, A is the Australian block, and B is the Tongling block. Manganese ore in the following weight ratio: A 55% and B 45% are configured into a mixed ore, and the Mn content in the obtained mixed ore is 20.73%, and the Fe content is 32.9%. These two manganese ores are processed to a particle size of 20-40mm.
[0069] And according to CaO / SiO 2 =0.35, then it is necessary to add 2.25Kg of quicklime with a CaO content of 85% to 100Kg of mixed ore to obtain a mixture. The particle size of quicklime is 3-10mm.
[0070] The coke is first-grade coke (ash content 12-12.5), and the particle size is processed to 25-50mm.
