Unlike Australia, Gabon, Brazil, and other countries that are dominated by manganese oxide ore, Ghana is dominated by high-grade manganese carbonate ore and is the only country in the world that has achieved large-scale mining and stable export of high-grade manganese carbonate ore.\u003C\u002Fp>\u003Cp>By the end of 2025, Ghana's manganese ore reserves stood at 69 million tonnes (in terms of metal content) [1], ranking fifth in the world. Ghana's manganese carbonate ore is produced at the Nsuta mining area in the southwest of the country, the world's sole supply base for high-grade manganese carbonate ore. In 2017, Ningxia Tianyuan Manganese Industry Group completed the full acquisition of Consolidated Minerals Limited (CML) of the United Kingdom, thereby indirectly holding equity in Ghana Manganese Company Limited and taking full responsibility for the development and operation of the Nsuta Mine. Supported by the refined management and operation of Ningxia Tianyuan Manganese Industry Group, Ghana's manganese carbonate ore output rose from 2.31 million tonnes in 2020 to 5.19 million tonnes in 2025, an increase of 124.68%.

Production data from Ningxia Tianyuan Manganese Group shows that when EMM is produced entirely from high‑grade Ghanaian manganese carbonate ore, manganese‑slag output per tonne of product falls sharply from 10 tonnes (using low‑grade domestic Chinese ore) to approximately 4 tonnes — a 60 % reduction. This meets Level‑I cleaner‑production requirements and performs far better than the Level‑I threshold. Based on China’s 2025 national EMM output of 1.479 million tonnes, full adoption of Ghanaian manganese carbonate ore could cut annual manganese‑slag generation by 4.3 million tonnes, delivering remarkable source‑reduction benefits. Against the backdrop of China’s push for source reduction of industrial solid waste and “zero‑waste city” initiatives, utilising imported high‑grade manganese ore has become a logical industry trend for the green transition of China’s electrolytic‑manganese sector.\u003C\u002Fp>\u003Cp>In addition, manganese slag derived from high‑grade Ghanaian manganese carbonate ore offers distinct advantages in terms of harmless disposal and comprehensive resource recovery compared with slag generated from low‑grade domestic Chinese manganese carbonate ore. Thanks to its high ore grade, less slag is produced. Harmless treatment via high‑temperature calcination consumes relatively little energy, making the process technically simpler and economically viable. Following high‑temperature calcination, sulphur can be efficiently recovered to produce sulphuric acid, which is recycled back into EMM manufacturing and substantially lowers overall production costs. Desulphurised manganese slag can further be processed into cement, building materials, autoclaved bricks, construction aggregates and sub‑grade fill for roadbeds, achieving high‑value resource utilisation.\u003C\u002Fp>\u003Ch2 style=\"text-align: left; line-height: 2.5;\">V. A Universally Adaptable \"All-Purpose Ore\": Sintered Manganese Ore Opens a New Path to Lower Cost and Higher Quality in Manganese Alloys\u003C\u002Fh2>\u003Cp style=\"text-align: left;\">Ghanaian manganese carbonate ore has long been known as an \"all-purpose ore.\" In addition to its core strategic value in electrolytic manganese metal production, it also demonstrates all-round quality and cost advantages in the production of manganese ferroalloys, making it the core high-quality raw material for optimizing the raw-material mix of China's silicomanganese industry and breaking the supply bottleneck of high-grade ore.\u003C\u002Fp>\u003Cp style=\"text-align: left;\">\u003Cbr>\u003C\u002Fp>\u003Cp style=\"text-align: center;\">\u003Cimg src=\"\u002Fv1\u002Fassets\u002Fnews\u002F2026\u002F08\u002F17\u002Fd1dab1f3d4cc469581024a9cc804420e.jpg\" alt=\"\" data-href=\"\" style=\"width: 50%;\">\u003C\u002Fp>\u003Cp>Using Ghanaian manganese carbonate ore to produce manganese alloys offers the following outstanding features and advantages. First, Ghanaian manganese carbonate ore is among the commercial manganese ores with the highest Mn\u002FFe ratio in the world, and its basicity (MgO+CaO)\u002FSiO2 falls exactly within the furnace-feed basicity range of 0.6–0.8 for silicomanganese production, so pure Ghanaian manganese carbonate ore alone can fully produce silicomanganese while greatly reducing the addition of flux raw materials such as dolomite, directly lowering power consumption in the smelting process. Second, after sintering and enrichment (hereinafter \"Ghanaian sintered manganese ore\"), the manganese grade can be raised to above 40% with the Mn\u002FFe ratio maintained above 24; its stable composition, large specific surface area, high mechanical strength, and good burden permeability substantially lower the strength requirements for reductants, allowing semi-coke to replace coke at a ratio of up to 60%, effectively reducing production costs while facilitating the long-term stable operation of the submerged arc furnace—offering significant advantages over producing silicomanganese from South African semi-carbonate manganese ore. Third, Ghanaian sintered manganese ore can directly replace manganese-rich slag as a high-grade manganese ore, eliminating the energy consumption and emissions of the manganese-rich slag production stage and further simplifying the process and compressing intermediate costs. Fourth, Ghanaian sintered manganese ore can also be flexibly blended with high-iron manganese ore to optimize the raw-material mix through precise proportioning, greatly reducing the overall production cost of silicomanganese while guaranteeing product grade. In addition to silicomanganese, Ghanaian sintered manganese ore also shows considerable potential in producing high-silicon silicomanganese, ferromanganese, and other manganese alloy products. Overall, Ghanaian manganese carbonate ore is characterized by a wide range of applications, large market absorption capacity, and high quality reliability, giving it extremely strong differentiated competitiveness in the global manganese alloy raw-material market.\u003C\u002Fp>\u003Ch2 style=\"text-align: left; line-height: 2.5;\">VI. Broad Long-Term Growth Prospects: Continuously Expanding Resource Value and Application Scenarios\u003C\u002Fh2>\u003Cp>As a globally scarce base of high-grade manganese carbonate resources, Ghana's manganese ore industry holds tremendous potential for future development:\u003C\u002Fp>\u003Cp>First, ample room for releasing resources and production capacity. The area currently explored by Ghana Manganese Company is less than 180 km², whereas the total mining-rights area is about 567.53 km². Taking into account the local geological conditions and the fact that the Yaka and Ndobonso areas have never undergone large-scale mining historically, the prospective resources of Ghana's manganese ore are estimated to exceed 2.6 billion tonnes[2]. Ningxia Tianyuan Manganese Industry Group has continued to step up its development of Ghana's manganese ore resources, purchasing large numbers of mining excavators, mining trucks, and other auxiliary mining equipment, and, through cooperation with large central state-owned enterprises, renovating and upgrading port yards and railway transport lines. Ghana's annual output of high-grade manganese carbonate ore is expected to achieve exponential growth.\u003C\u002Fp>\u003Cp>Second, the new-energy sector opens a new track. With the rapid development of the global new-energy vehicle and new-type energy-storage industries, demand for trimanganese tetroxide (Mn3O4), high-purity manganese sulfate, and manganese-based materials such as lithium manganese iron phosphate (LMFP) and lithium-rich manganese-based cathodes has surged. The low-impurity, easy-to-purify characteristics of Ghanaian manganese carbonate ore give it natural advantages in preparing electrolytic manganese and manganese-based battery materials. Amid the vigorous development of the new-energy battery industry, manganese carbonate ore—with its significant advantages of directly producing high-end manganese products and its broad applicability—is expected to unlock long-term growth potential.\u003C\u002Fp>\u003Cp>Third, China–Africa cooperation releases policy dividends. China has listed manganese as a strategic mineral and supports enterprises in carrying out overseas resource development in an orderly manner. China and Ghana enjoy deep political mutual trust and strong economic complementarity, and mining cooperation is a core pillar of their bilateral practical cooperation, providing solid support for the overseas resource deployment of Chinese enterprises. Ningxia Tianyuan Manganese Industry Group attaches great importance to its relationship with the Ghanaian government. While developing mining, it also helps Ghana grow its economy, improve infrastructure, increase employment, and better people's livelihoods, creating a favorable external environment for the sustained development of Ghana's high-grade manganese carbonate ore.\u003C\u002Fp>\u003Cp>As the world's sole source of high-grade manganese carbonate ore, Ghana has become an irreplaceable and indispensable part of the global manganese industry landscape. As a globally unique and scarce resource, Ghanaian manganese carbonate ore will continue to grow in strategic value and become an important force driving the green and low-carbon transformation of the global manganese industry chain.\u003C\u002Fp>\u003Cp style=\"text-indent: 22.95pt;\">\u003Cbr>\u003C\u002Fp>\u003Cp style=\"text-indent: 22.95pt;\">\u003Cbr>\u003C\u002Fp>\u003Cp>References:\u003C\u002Fp>\u003Cp>[1] USGS Mineral Commodity Summaries (2026); Ghana Manganese Company JORC Resource Report\u003C\u002Fp>\u003Cp>[2] Ghana Manganese Company internal materials\u003C\u002Fp>\u003Cp>\u003Cbr>\u003C\u002Fp>\u003Cp>\u003Cbr>\u003C\u002Fp>","2026-08-17T05:52:08Z",39,false,"2026-08-17T03:06:32.506Z","2026-08-18T02:12:07.339Z",{"id":18,"title":23,"summary":26,"cover":29,"body":30,"publishedAt":33,"viewCount":34,"isMemberOnly":35,"createdAt":36,"updatedAt":37},{"zh-CN":24,"en-US":25},"电解锰市场分化：美国价格上行，中国外销走弱","EMM Markets Diverge as US Prices Rise While Chinese Exports Soften",{"zh-CN":27,"en-US":28},"本周中国与美国电解金属锰行情走势分化。","The Chinese and US electrolytic manganese metal markets moved in opposite directions this week.","\u002Fv1\u002Fassets\u002Fnews\u002F2026\u002F08\u002F17\u002F14d09f124a1b42a1a566a11cd1b1f6bd.jpg",{"zh-CN":31,"en-US":32},"\u003Cp style=\"text-indent: 2em; text-align: left;\">2026 年 8 月 14 日\u003C\u002Fp>\u003Cp style=\"text-indent: 2em; text-align: left;\">\u003Cspan style=\"color: rgb(0, 0, 0);\">国内片状电解锰出厂价维持 17550-17650 元 \u002F 吨区间稳定，招标价形成支撑。河钢签订 1215 吨采购长单，完税后交货价 18800 元 \u002F 吨，与 7 月采购价持平；但现货需求清淡，部分厂商选择降价出货。\u003C\u002Fspan>\u003C\u002Fp>\u003Cp style=\"text-indent: 2em; text-align: left;\">\u003Cspan style=\"color: rgb(0, 0, 0);\">欧洲市场进入传统淡季，中国电解锰外销报价走弱：片状电解锰离岸价 2590-2620 美元 \u002F 吨，块状电解锰离岸价 2620-2640 美元 \u002F 吨。\u003C\u002Fspan>\u003C\u002Fp>\u003Cp style=\"text-indent: 2em; text-align: left;\">\u003Cspan style=\"color: rgb(0, 0, 0);\">与之相反，美国电解锰市场走强，市场估价 158-165 美分 \u002F 磅出厂，此前区间为 155-165 美分 \u002F 磅。汽车行业需求回暖、海运集装箱运费上涨共同推高价格；叠加中国、印尼潜在供应收缩，短期行情存在支撑。\u003C\u002Fspan>\u003C\u002Fp>","\u003Cp>14 August 2026\u003C\u002Fp>\u003Cp>\u003Cbr>\u003C\u002Fp>\u003Cp>In China, domestic EMM flake prices remained relatively stable at RMB 17,550–17,650\u002Ft EXW, supported by stable tender prices.
