Embodiment 1
[0015] Embodiment 1: 100g pyrolusite powder (containing manganese 55.5%, Fe 2 o 3 6.7%, particle size 180 mesh) and rice straw powder (1.5mm) 88g were added to a stainless steel pressure reactor with a volume of 10L, and the concentration was 30g / L, Mn(NO 3 ) 2 4300ml of 400g / L mixed solution was leached for 2h at 40℃~50℃ under airtight stirring (stirring speed 70r / min). According to the laboratory analysis results of the washed leaching slag, the leaching rate of manganese is 99.2%.
Embodiment 2
[0016] Embodiment 2: 1000g pyrolusite powder (containing manganese 55.5%, Fe 2 o 3 6.7%, particle size 180 mesh) and rice straw powder (1.5mm) 1005g into a stainless steel pressure reactor with a volume of 50L, the concentration of adding is 50g / L, Mn(NO 3 ) 2 26L of 150g / L mixed solution was leached for 1h at 50℃~60℃ under closed stirring (stirring speed 60r / min). According to the laboratory analysis results of the washed leaching slag, the leaching rate of manganese is 99.4%.
