Embodiment 1
[0028] The Algerian high-arsenic manganese ore containing 37.09% by weight of manganese and 4.92% by weight of arsenic is subjected to dry strong magnetic separation under the technological conditions of a magnetic field strength of 13,000 Oersted, and the raw manganese ore selected is then ground into After the particle size of 60% is -0.074mm, under the technological condition that the magnetic field strength is 9000 Oersted, carry out wet strong magnetic separation, and then use the sulfuric acid with the concentration of 98% of the ore in an amount of 360Kg / t and the H of the ore in an amount of 1Kg / t 2 o 2 , carry out the wet chemical leaching reaction, the reaction time is 3 hours, the leachate in the upper layer of the reaction liquid precipitation is reused, the manganese slag is treated with calcium salt to achieve discharge, the reaction liquid precipitate is neutralized with lime milk solution, and the pH value is controlled at 7 to obtain manganese Concentrate prod...
Embodiment 2
[0031] The high-arsenic manganese ore containing 36.27% by weight of manganese and 5.03% by weight of arsenic is subjected to dry strong magnetic separation under the technological conditions of a magnetic field strength of 12000 Oersted. After the particle size of % is -0.074mm, under the process condition that the magnetic field intensity is 8500 Oersted, carry out wet strong magnetic separation, and then use the sulfuric acid with the concentration of 98% of the ore in the amount of 355Kg / t and the concentration of the ore in the amount of 0.9Kg / t h 2 o 2 , carry out the wet chemical leaching reaction, the reaction time is 2.5 hours, the leaching solution of the upper layer of the reaction liquid precipitation is reused, the manganese slag is treated with calcium salt to achieve discharge, and the reaction liquid precipitate is neutralized with lime milk solution, and the pH value is controlled at 6.6 to obtain manganese Concentrate products.
