Energy minerals: mainly coal, peat soil and underground hot water. Coal resources are 2665438+ ten thousand tons, mainly distributed in Longmen and Huiyang counties (districts). Most of them belong to anthracite with low calorific value, and the scale is small. Except for a few producing areas, most of them have no development and utilization value. According to the geological exploration and evaluation, there are 8 underground hot water occurrences 18, and the allowable exploitation amount is 6000m3/day, mainly distributed in Longmen and Boluo counties. Among them, Longmen Longcheng Hot Pot and Longmen Land have a large amount of water, and the water temperature reaches 44 ~ 76℃, which has a good development prospect.
Metal minerals: mainly iron, tungsten, lead and zinc, niobium, tantalum and ilmenite. There are 22 iron ore producing areas, with resources of 26 million tons, mainly distributed in Boluo, Huidong and Huiyang counties (districts), with medium-sized 1, and the rest are small or ore occurrences. The resource of Borolli Mountain Iron Mine is 6.5438+009600 tons, and the grade of total iron is 363. 1%. Associated lead, zinc and tin can be comprehensively utilized. Lead-zinc mine resources amount to 1 10,000 tons, mainly distributed in Huiyang and Longmen. The fresh water in Longmen, Chapai and Huiyang can reach medium scale, with the lead and zinc grade of 1 1%, and the associated elements of copper, iron, silver and cadmium can be comprehensively recovered. Niobium and tantalum are the dominant minerals in this city, with a resource of nearly 80,000 tons, with 12 mineral deposits, mainly distributed in Huiyang, Boluo and Longmen counties (districts). There are 8 medium-sized or above deposits, including 3 large-scale deposits. Longmen Yonghan Niobite has a large reserve and high grade, reaching 70,000 tons, and the associated monazite can reach a medium scale.
Non-metallic minerals: mainly granite, feldspar, limestone for cement and glass quartz sand for building. Geological exploration and evaluation of 9 medium-sized and above deposits. Crystal minerals are mainly distributed in Xintian, Gaolangwei and other places in Huidong County, with a resource of 4,585 kg (piezoelectric crystals). The Tankeng potash feldspar deposit in Huiyang District has a large scale, with an estimated reserve of 1, 486,5438+0,000 tons, a good grade and a K2O content of 1, 654,38+0%. The limestone resources for cement are 65.438+0.35 billion tons, and the scales of Boluo Lishan, Huidong Lingkeng and Longmen Xianniangniang are all medium-sized. The quality of limestone is good, and the CaO content is between 50% and 54%, which belongs to high-quality cement-muddy limestone. The resources of Gabi glass placer in Huidong County are 3.95 million tons, and the silica content of raw ore is 96.62%, which is a high-quality raw material for making flat glass. Building granite is widely distributed, and its lithology is mainly Yanshanian light-fleshed red adamellite, which is generally good in stone quality and is a high-quality raw material for building stone. In some areas, the waste rate of granite is up to 30%, which can be used as raw materials for middle and low-grade building facing stone.
Water and gas minerals: mainly drinking groundwater and normal temperature mineral water. The origin of mineral water is 16, and the total allowable exploitation amount is 3728 cubic meters/day, mainly distributed in Boluo, Longmen and Huidong counties, all of which belong to metasilicate mineral water with low salinity. Among them, Huyanshan and Boluo Shikan mineral water in Huidong contain trace strontium, Longmen Xianlong mineral water and Huicheng Tonghu mineral water have large reserves and high metasilicic acid content, which are high-quality mineral water with good development prospects.
