  • Since the country's opening to the world, China's rapid economic growth has resulted in strong demand for a wide variety of mineral commodities. During the same period, China's mineral production increased sharply. China's increased mineral production and demand affected the worldwide availability of minerals and metals, the market prices, and trade. Ministry of Land and Resources of China (MLR) planned to build as many as 10 strategic mineral reserve, including reserves of aluminium, copper, manganese, uranium, and other mineral that the country urgently needed. In white paper of China's mineral resources, China is planning the mineral resources conservation and its reasonable utilization, domestic supply increase of resources, activation of cooperative development with foreign partners, balance in resources development and environment conservation, and sustainable resources management as the mineral resources policies for the China's economic development.

  • Given that China's resource research, exploration and development and resource economy policies are closely related to Korea's industrial competitiveness in the field of global mineral energy resources, it is important to establish the domestic and overseas resource development strategies. In 2020, China will revise and set standards for mineral resources to ensure efficiency in exploration and development and storage management. China's Ministry of Natural Resources has established the National Mineral Resources Plan (2021-2025), aiming to achieve national goals and strategies, and local governments at all levels are also establishing and implementing regional mineral resources plans. As a result, the supervision and management of geological mineral exploration activities have been strengthened, and the safety of industrial production management in the field of geological mineral exploration and development has been strengthened. China has developed guidelines for high-quality geological exploration, surveying and mapping, improved the level of geological mineral exploration and strengthened the mining supervision and management system. According to China's standardization of mineral resources such as solid mineral resources and petroleum gas mineral resources, a new standard system for resource management will be established in China to improve scientific understanding, rational management and utilization.

  • 한동안 일본의 급성장 수출경제는 멈출 수 없는 것처럼 보였었다. 그러나 이제 지난 10년간 경제가 후퇴하면서 그 희생을 치르고 있다. 제조업 전 분야가 하락세를 면치 못하고 있거나, 기껏해야 현상 유지함으로서 결국 광물 소비량에 영향을 미치고 있다. 대규모 석회석 백운석 자원, 상당한 벤토나이트 및 납석 자원, 그리고 소다회, 융합광물(fused minerals) 등의 합성 원료를 제외하면, 일본에는 규모 있는 광물자원이 거의 없다. 광물자원의 부족과 최근의 엔고 현상 때문에 일본은 중국과 같은 나라의 주요 광물 수출 시장이 되고 있다.

  • Due to growing problems securing stable mineral and energy resources with international political and economic changes, China has dedicated itself to strategies and policies to enhance its stable mineral and energy resources security. China has established a rare earth elements(REE) industry policy after the abolition of the REE exports quota system. China's six large REE companies have also been integrated into REE mining, smelting and refining companies. Efforts have been increased to enhance China's energy security through unconventional oil and gas exploration and development investment, as well as effort in R&D. The country will focus on technology development and exploration to promote commercial production of unconventional oil and gas based on countries with shale gas. China is making long-term contracts and joint ventures to ensure the acquisition of reliable mineral and energy resources from abroad. Government of China has proposed a range of initiatives, such as the integration of resources development strategies and environmental development strategies, internationalization of resource management, supply diversification and advancement, strengthening industry linking strategy, grouping and diversification strategy.

  • The Chinese government and its agencies were trying in order to solve the unstability of resource supply and demand. Ministry of Land and Resources of China(MLR) carried out a lot of national-level policy and planning for estimating the domestic mineral and energy resources potential and recoverable reserves, as the Chinese land and resources survey plan(1999~2010), the Chinese mineral resource survey and exploration plan(2008~2020), announcement for shale gas industry policies of China, the Chinese shale gas resources evaluation and selection project for its development priority areas(2012), and the plan for Chinese shale gas development(2011~2015). The two large sedimentary basins of Chinese shale gas reserves are Sichuan and Tarim basins with excellent potential, accounting for majority of the estimated national reserves. Recoverable gas-bearing shale of China was surveyed to be widespread. The volume of recoverable shale gas reservoirs in China has been estimated to be around 31 trillion cubic meters(1,115 trillion cubic feet). China is one of only three countries with the US and Canada to produce shale gas in commercial quantities. China is concentrating on technology development to enhance commercial production of shale gas, and on survey and exploration activities to increase its recoverable reserves. The trends related to shale gas development and R&D activities in China to respond to changes in international oil market should be actively monitored based on analysis of Chinese policies and technology.

  • Recently, there has been a rapid response from mineral-demanding countries for securing critical minerals in a high tech industries. Graphite, while overwhelmingly dominated by China in production, is changing in global supply due to the exponential growth in EV battery sector, with active exploration in East Africa. Rare earth elements are essential raw materials widely used in advanced industries. Globally, there are ongoing developments in the production of REEs from three main deposit types: carbonatite, laterite, and ion-adsorption clay types. While China's production has decreased somewhat, it still maintains overwhelming dominance in this sector. Recent changes over the past few years include the rapid emergence of Myanmar and increased production in Vietnam. Nickel has been used in various chemical and metal industries for a long time, but recently, its significance in the market has been increasing, particularly in the battery sector. Worldwide, nickel deposits can be broadly classified into two types: laterite-type, which are derived from ultramafic rocks, and ultramafic hosted sulfide-type. It is predicted that the development of sulfide-type, primarily in Australia, will continue to grow, while the development of laterite-type is expected to be promoted in Indonesia. This is largely driven by the growing demand for nickel in response to the demand for lithium-ion batteries. The global lithium ores are produced in three main types: brine lake (78%), rock/mineral (19%), and clay types (3%). Rock/mineral type has a slightly higher grade compared to brine lake type, but they are less abundant. Chile, Argentina, and the United States primarily produce lithium from brine lake deposits, while Australia and China extract lithium from both brine lake and rock/mineral sources. Canada, on the other hand, exclusively produces lithium from rock/mineral type. Vanadium has traditionally been used in steel alloys, accounting for approximately 90% of its usage. However, there is a growing trend in the use for vanadium redox flow batteries, particularly for large-scale energy storage applications. The global sources of vanadium can be broadly categorized into two main types: vanadium contained in iron ore (81%) produced from mines and vanadium recovered from by-products (secondary sources, 18%). The primary source, accounting for 81%, is vanadium-iron ores, with 70% derived from vanadium slag in the steel making process and 30% from ore mined in primary sources. Intermediate vanadium oxides are manufactured from these sources. Vanadium deposits are classified into four types: vanadiferous titanomagnetite (VTM), sandstone-hosted, shale-hosted, and vanadate types. Currently, only the VTM-type ore is being produced.

  • 국내에는 충주 어래산 광화대와 홍천 광화대에 대한 탐사 결과 약 4,600,000 톤의 자원량을 확보하였으나 시추량의 제한에 따른 자원량의 부족과 낮은 가격으로 인해 경제성이 없는 것으로 잠정적으로 판단된 바 있다. 그러나 최근 희토류 가격이 2000년대 초에 비해 2~3배까지 상승하였으며 최저개발 품위가 REO 2%대로 낮아짐으로써 두 광화대에 대한 체계적인 정밀탐사를 통하여 보다 정확한 자원평가가 요구된다. 이 두 지역은 REE 뿐만 아니라 Fe, Sr 등이 수반됨으로써 그 잠재적인 가치를 높일 수 있을 것으로 판단된다. 하동 광화대는 Ti외 REE와 Li의 추출이 가능하여 경제성을 상승시킬 수 있을 것으로 판단된다. 양양 광화대는 Zr-Nb-REE 광화대로 알려져 있으나 체계적 탐사가 수행되지 않아 자원량의 산정은 수행되지 않았으나 REE 외 희유금속인 Nb을 수반하여 그 잠재적인 가치가 높다고 판단된다. 국내 REE 자원탐사는 체계적이고 계획적인 탐사가 진행 된 적이 없어 단일 광상에 대해 정확한 매장량 산정이나 경제성 분석 등이 이루어지지 않아 그 가치 판단이 모호함으로써 개발에 제한을 가지고 있다. 세계적인 수요량이 현재 REO 100,000톤에서 2013년에는 거의 200,000톤으로의 증가가 전망되고, Eu의 가격은 2000년 중반에 비해 최근 2배 상승하였으며, Dy의 가격은 3배 이상 급상승 추세에 있어 대부분 희토류 산화물 가격은 점차 증가될 것으로 전망한다. 전 세계 희토류 생산의 95%를 중국이 독점하고 있어 자원이 1개국에 편재된 극히 좋지 않은 자원환경으로 세계 각국에서 희토류 탐사에 전념하고 있는 실정이다. 아울러 하이브리드 카 생산이 증대되면 중국만이 생산하는 중희토류의 수요가 급증하여 가격 상승과 함께 수급에 차질이 있을 것으로 추측된다. 따라서 국내 희토류 자원에 대한 체계적이고 단계적인 중장기적 탐사를 통하여 REE 자원을 확보하여 개발한다면 국내 REE 자원의 수급을 원활히 할 수 있을 것으로 기대된다.
