Abstract
Description
technical field
[0001] The invention relates to a manganese ore leaching process, which is especially suitable for rhodochrosite ore processing. Background technique
[0002] Rhodochrosite ore is the basic raw material for the production of manganese series products in my country, such as electrolytic manganese metal, electrolytic manganese dioxide, manganese sulfate, manganese carbonate, etc. They generally use manganese-rich solution processed from rhodochrosite ore as an intermediate product. The processing technology of manganese ore usually includes "ore - crushing - grinding to -200~-300 mesh ore powder - mixing with concentrated sulfuric acid for aging or directly adding to a large stirring tank for stirring and leaching - filter press for solid-liquid separation and slag removal - —Manganese-rich solution. This technique is only suitable for manganese-rich ore. For low-grade ores, the cost is too high and generally cannot be used; a small nu...
