Electrolytic manganese metal (i.e. electrolytic manganese) is elemental metal separated from electrobath in which manganese salt is electrolyzed after lixiviated by strong acid from manganese ore. Electrolytic manganese looks like iron and appears in irregular flakes which are hard and fragile. Electrolytic manganese contains manganese up to 99.7 ~ 99.9% so it’s purity is very high. It’s used for increasing hardness of alloy metal materials and most widely used for manganese-copper alloy, manganese-aluminum alloy and 200 series stainless steel in which manganese can improve its tensile strength, toughness, wear resistance and corrosion resistance. Use of manganese in the steel industry account for up to 90～95％, which is so-called “No steel without manganese”.
The most abundant distribution of manganese is in Guangxi and Hunan, which account for 55% of total reserves in China, followed by in regions Guizhou, Yunnan, Liaoning and Sichuan. Production of electrolytic manganese is mainly concentrated in the areas Jishou of Hunan, Songtao of Guizhou, Xiushan of Chongqing and Daxin of Guangxi, especially the “Manganese Triangle” connected by Jishou of Hunan, Songtao of Guizhou and Xiushan of Chongqing is the most famous. Main items of electrolytic manganese include #997/999 manganese flakes, #95/96/97 manganese ingots, manganese briquettes and manganese lumps. |
