Abstract: This paper, based on the actuality of Guangxis manganese industry, uses statistics to analyze the manganese production and guarantee extent of manganese resource in the 13rd fiveyearplan. Ferroalloy production is predicted to be 5.86 million tons in 2020 by an annual rising rate 2.8%, electrolyzed metal manganese to be 348.600 tons and electrolyzed manganese dioxide to be 288.800 tons in 2020 by an annual rising rate 10%. Guangxi's remaining manganese reserve is 3665 million tons in manganese oxide, 92.41 million tons in manganese carbonate. Manganese oxide is predicted to be 3.8255 million tons in 2010 by an annual rising rate 2%, manganese carbonate 3.9683 million tons by 10%. During the 13rd fiveyearplan, Guangxi's manganese mines can only supply the 33%—35% of the demand of manganese oxide, with the rest relying on import or transfer. Its manganese carbonate production can fully meet the need of electrolyzed metal manganese and electrolyzed manganese dioxide.
