广西锰矿资源对“十三五”锰产业的保障程度分析

GUARANTEE EXTENT OF“THE 13^(rd) FIVE-YEAR-PLAN”MANGANESE INDUSTRY OF GUANGXI'S MANGANESE RESOURCE

在广西锰产业现状调查的基础上,采用数据统计的方法分析预测"十三五"期间广西锰系产品的产量以及锰矿资源对锰产业的保障程度。预测铁合金产量将以2.8%的年增长速度增长,2020年将达到586万t;预测广西电解金属锰和电解二氧化锰产量的年均增长速度为10%,到2020年产量将分别达到34.86万t和28.88万t。广西目前保有的锰矿资源储量中可供的氧化锰矿为3 665万t,可供的碳酸锰矿为9 241万t。预测"十三五"期间广西氧化锰矿和碳酸锰矿的产量将分别以2%和10%的速度增长,到2020年将分别达到382.55万t和396.83万t。"十三五"期间广西矿山氧化锰矿产量只能满足铁合金产业33%~35%的需求,剩余65%~67%的需求要通过区外调入和进口解决,广西矿山碳酸锰矿产量完全能满足电解金属锰和电解二氧化锰产业的需求。

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 13rdfive-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. 825 5 million tons in 2010 by an annual rising rate 2%,manganese carbonate3. 968 3 million tons by 10%. During the 13rdfive-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.
