Most are manganese oxide ore deposits Eluvial secondary ore, soft texture, containing more clay minerals, the mining of clay and easy handling process, the clay content is usually 20% to 70%, in order to improve ore The manganese-containing grade and improved crushing, sieving, beneficiation and transportation conditions all require washing. Coarse grain The pre-miao mining area of ​​Liancheng manganese mine in Fujian Province is a weathering crust-manganese-manganese deposit, which is divided into leaching type, slope type and leaching and slope type mixing type, mainly leaching type. The main ore minerals are hard metal manganese ore, manganese ore, manganese soil and brown iron ore and other gangue minerals are dominated by quartz, followed by sericite, opal, barite, other impurities are mainly loess, clay. The ore process is a washing-jigging-strong magnetic separation process. Broken to The SPH type strong magnetic separator is also used for the magnetic separation of manganese oxide ore.
