中国钼矿资源供需预测 总被引：3，自引：0，他引：3
本文在对我国钼矿成矿地质条件、资源储量、开发利用现状、产业与市场进行分析的基础上,分析了我国钼矿资源的特点及产业发展趋势。利用矿产品部门消费法和回归分析法,对我国2020年、2025年和2030年钼矿资源性产品的需求量(金属量,下同)和产量(能)进行了预测。预测结果表明:2020年、2025年和2030年我国钼矿消费量分别为:8.26~8.3万吨、8.77~9.0万吨、9.22~9.5万吨;产量(能)分别为:12万吨、10万吨和9.5万吨。研究表明:我国钼矿资源储量大,以斑岩型矿床为主,品位低(0.056%),高品位(Mo≥0.12%)的保有资源储量占比不足1/5,单矿石可选性好;在一段时间内仍将维持供大于求的格局,钼精矿产能利用率持续降低。为此,本文提出通过实施严格控制钼矿开采总量、提高环保准入门槛,以及去产能化等对策建议,解决我国钼矿资源产业中存在的问题。本文研究结论对我国钼矿资源产业可持续发展战略制定等具有重要的参考价值。 相似文献

铬铁矿是我国急缺的战略矿产之一,主要来源依靠进口,由于资源储量和生产量有限,供需缺口连年加大。本文在全国重要矿产资源潜力评价数据成果基础上,对全国铬铁矿资源进行潜力预测。通过对我国铬铁矿产分布特征、成矿类型的系统分析,进行了成矿区带划分,划分出4个Ⅰ级成矿域、11个Ⅱ级成矿省和20个Ⅲ级成矿带。综合成矿规律,归纳出预测要素,建立了两种预测评价模型,分别为与超基性岩有关的侵入岩体型铬铁矿和与超基性岩有关的似层状岩浆型铬铁矿。在充分收集整理各省铬铁矿地质资料基础上,以GIS的矿产资源预测与评价为手段,开展了预测区的圈定与优选,重点筛选出3个预测资源量较大可达到500万t以上的铬铁矿三级预测区,进行了简单的资源评价,探讨铬铁矿资源潜力,提出找矿建议。评价数据显示,全国铬铁矿资源总量7 215.32万t;累计查明铬资源量共计1 565.59万t;预测铬资源量共计5 649.73万t。综合分析铬铁矿研究区已有工作成果和找矿进展,结合全国重要矿产资源潜力评价最新成果,认为在新疆萨尔托海、西藏罗布莎、甘肃大道尔吉等地区资源潜力巨大,是主要找矿方向,可作为重点找矿部署区。 相似文献

安徽省是煤炭资源大省,含煤面积约1.79万km^2,煤炭赋存量居华东第一。自上个世纪50年代以来,安徽省煤田地质局共提交各类地质报告和资料694件,累计查明资源储量约300亿t,保有资源储量约260亿t。目前,两淮煤田勘查深度一般为-1000～-1200m,埋深-1200～-1500m的煤田勘探多属空白。针对安徽省当前煤炭勘探形势,安徽省煤田地质局以新增煤炭资源储量为目标,利用现代地学理论为指导,加大科研和装备投入,实现了深部矿床勘探中的重大突破。随着深部勘探程度的提高,预计可为安徽新增煤炭资源储量近200亿t,这将大大缓解安徽省的煤炭供需矛盾。安徽省煤田地质局深部找煤的重大突破,对于提高煤炭供应能力具有重要的找矿指导意义。 相似文献

Development and Utilization of the World’s and China’s Bulk Mineral Resources and their Supply and Demand Situation in the Next Twenty Years 总被引：1，自引：0，他引：1
Bulk mineral resources of iron ores, copper ores, bauxite, lead ores, zinc ores and potassium salt play a pivotal role on the world’s and China’s economic development. This study analyzed and predicted their resources base and potential, development and utilization and their world’s and China’s supply and demand situation in the future 20 years. The supply and demand of these six bulk mineral products are generally balanced, with a slight surplus, which will guarantee the stability of the international mineral commodity market supply. The six mineral resources(especially iron ores and copper ores) are abundant and have a great potential, and their development and utilization scale will gradually increase. Till the end of 2014, the reserveproduction ratio of iron, copper, bauxite, lead, zinc ores and potassium salt was 95 years, 42 years, 100 years, 17 years, 37 years and 170 years, respectively. Except lead ores, the other five types all have reserve-production ratio exceeding 20 years, indicative of a high resources guarantee degree. If the utilization of recycled metals is counted in, the supply of the world’s six mineral products will exceed the demand in the future twenty years. In 2015–2035, the supply of iron ores, refined copper, primary aluminum, refined lead, zinc and potassium salt will exceed their demand by 0.4–0.7 billion tons(Gt), 5.0–6.0 million tons(Mt), 1.1–8.9 Mt, 1.0–2.0 Mt, 1.2–2.0 Mt and 4.8–5.6 Mt, respectively. It is predicted that there is no problem with the supply side of bulk mineral products such as iron ores, but local or structural shortage may occur because of geopolitics, monopoly control, resources nationalism and trade friction. Affected by China’s compressed industrialized development model, the demand of iron ores(crude steel), potassium salt, refined lead, refined copper, bauxite(primary aluminum) and zinc will gradually reach their peak in advance. The demand peak of iron ores(crude steel) will reach around 2015, 2016 for potassium salt, 2020 for refined lead, 2021 for bauxite(primary aluminum), 2022 for refined copper and 2023 for zinc. China’s demand for iron ores(crude steel), bauxite(primary aluminum) and zinc in the future 20 years will decline among the world’s demand, while that for refined copper, refined lead and potassium salt will slightly increase. The demand for bulk mineral products still remains high. In 2015–2035, China’s accumulative demand for iron ores(crude steel) will be 20.313 Gt(13.429 Gt), 0.304 Gt for refined copper, 2.466 Gt(0.616 Gt) of bauxite(primary aluminum), 0.102 Gt of refined lead, 0.138 Gt of zinc and 0.157 Gt of potassium salt, and they account for the world’s YOY(YOY) accumulative demand of 35.17%, 51.09%, 48.47%, 46.62%, 43.95% and 21.84%, respectively. This proportion is 49.40%, 102.52%, 87.44%, 105.65%, 93.62% and 106.49% of that in 2014, respectively. From the supply side of China’s bulk mineral resources, it is forecasted that the accumulative supply of primary(mine) mineral products in 2015–2035 is 4.046 Gt of iron ores, 0.591 Gt of copper,1.129 Gt of bauxite, 63.661 Mt of(mine) lead, 0.109 Gt of(mine) zinc and 0.128 Gt of potassium salt, which accounts for 8.82%, 13.92%, 26.67%, 47.09%, 33.04% and 15.56% of the world’s predicted YOY production, respectively. With the rapid increase in the smelting capacity of iron and steel and alumina, the rate of capacity utilization for crude steel, refined copper, alumina, primary aluminum and refined lead in 2014 was 72.13%, 83.63%, 74.45%, 70.76% and 72.22%, respectively. During 2000–2014, the rate of capacity utilization for China’s crude steel and refined copper showed a generally fluctuating decrease, which leads to an insufficient supply of primary mineral products. It is forecasted that the supply insufficiency of iron ores in 2015–2035 is 17.44 Gt, 0.245 Gt of copper in copper concentrates, 1.337 Gt of bauxite, 38.44 Mt of lead in lead concentrates and 29.19 Mt of zinc in zinc concentrates. China has gradually raised the utilization of recycled metals, which has mitigated the insufficient supply of primary metal products to some extent. It is forecasted that in 2015–2035 the accumulative utilization amount of steel scrap(iron ores) is 3.27 Gt(5.08 Gt), 70.312 Mt of recycled copper, 0.2 Gt of recycled aluminum, 48 Mt of recycled lead and 7.7 Mt of recycled zinc. The analysis on the supply and demand situation of China’s bulk mineral resources in 2015–2035 suggests that the supply-demand contradiction for these six types of mineral products will decrease, indicative of a generally declining external dependency. If the use of recycled metal amount is counted in, the external dependency of China’s iron, copper, bauxite, lead, zinc and potassium salt will be 79%, 65%, 26%, 8%, 16% and 18% in 2014, respectively. It is predicted that this external dependency will decrease to 62%, 64%, 20%,-0.93%, 16% and 14% in 2020, respectively, showing an overall decreasing trend. We propose the following suggestions correspondingly.(1) The demand peak of China’s crude steel and potassium salt will reach during 2015–2023 in succession. Mining transformation should be planned and deployed in advance to deal with the arrival of this demand peak.(2) The supply-demand contradiction of China’s bulk mineral resources will mitigate in the future 20 years, and the external dependency will decrease accordingly. It is suggested to adjust the mineral resources management policies according to different minerals and regions, and regulate the exploration and development activities.(3) China should further establish and improve the forced mechanism of resolving the smelting overcapacity of steel, refined copper, primary aluminum, lead and zinc to really achieve the goal of "reducing excess production capacity".(4) In accordance with the national strategic deployment of "One Belt One Road", China should encourage the excess capacity of steel, copper, alumina and primary aluminum enterprises to transfer to those countries or areas with abundant resources, high energy matching degree and relatively excellent infrastructure. Based on the national conditions, mining condition and geopolitics of the resources countries, we will gradually build steel, copper, aluminum and lead-zinc smelting bases, and potash processing and production bases, which will promote the excess capacity to transfer to the overseas orderly.(5) It is proposed to strengthen the planning and management of renewable resources recycling and to construct industrial base of renewable metal recycling.(6) China should promote the comprehensive development and utilization of paragenetic and associated mineral species to further improve the comprehensive utilization of bulk mineral resources. 相似文献

从煤炭资源、煤炭生产现状入手,按照煤炭资源区划,分析了我国煤矿现有产能及其分布,按照区域煤炭产能估算公式,测算我国已查明的资源储量仅能形成65亿t产能,其中东部地区仅为8亿t。对影响煤炭产能的水资源、生态环境、安全集约化生产、运输、大气环境等多种约束条件进行研究与评价,估算出我国煤炭科学产能为38亿t左右。通过煤炭资源保障程度的分析,认为我国煤炭资源总体保障程度高,但是东部地区煤炭供需矛盾突出,资源保障程度较低,主要炼焦配煤短缺局面仍未得到缓解,认为加强东部和稀缺煤种找矿力度,合理勘查开发周边国家煤炭资源,是缓解我国东部煤炭供应紧张局面的有效措施。 相似文献
