Lishui is the city with the richest mineral resources in this province, which has the characteristics of many types, concentrated distribution, large scale of deposits and excellent quality. 57 kinds of minerals and 494 occurrences have been discovered in China. Among them, there are 25 kinds of metallic minerals and 32 kinds of nonmetallic minerals. There are 0/3 large deposits/kloc-0, 39 medium deposits, 0/25 small deposits/kloc-0, and 3 occurrences 1 7 (see attached table1). Gold (silver), lead and zinc, molybdenum, rare earth, pyrophyllite, fluorite, kaolin, zeolite, perlite, ceramic clay, granite, tuff for building and other mineral resources are rich. The proven reserves of major minerals account for a high proportion of the total reserves in the province (see Table 2): gold accounts for 58.7%, molybdenum accounts for 56. 1%, lead and zinc account for 13.0% and 10.2% respectively, fluorite accounts for 20.5% and pyrophyllite accounts for 6/kloc-0.

Gold (silver) ore: mainly distributed in Suichang and Longquan, with 24.59 tons of rock gold and 978 tons of silver. Zhilingtou large gold deposit in Suichang County is rich in silver and gold. Jintiansi, Xia Ju and Babaoshan in Suichang are small gold (silver) deposits.

Lead-zinc mine: mainly distributed in Longquan, Suichang and qingtian county, with 423,400 tons of lead and zinc metal proved. Among them, Longquan Wuao lead-zinc deposit has reached a medium scale, and Qingtian Sunkeng, Suichang Ge Ping, Jingning Xiaohou, Qingyuan Yingyan, Longquan Baoxi, Cheyu, Songyang Dalingtou, Liandu Liyangkeng and Yinchang are all small deposits.

Molybdenum ore: mainly distributed in qingtian county, followed by Songyang County and Jingning County, with the proven molybdenum metal amount of 6.5438+0.93 million tons. Shipingchuan molybdenum mine in Qingtian has reached a medium scale. The ore is rich in grade and easy to mine and select.

Rare earth minerals: Qingyuan River bottom, Songyang Banqiao and Suichang Hushan rare earth deposits have been identified by geological survey in our province at present, and Qingyuan River bottom still has a good prospecting prospect.

Zeolite rock and perlite: concentrated in the area from Laohutou to Tianjingshan in Jinyun County, it is a super-large natural zeolite deposit first discovered in China in the early 1970s, with proven resource reserves of1.700 million tons, accounting for 99.3% of the total zeolite reserves in the province, and it is estimated that the prospective resources will reach more than 300 million tons. Perlite and zeolite have emerged, with proven ore resources of 6.5438+0.49 million tons and prospective resources of 60 million tons.

Fluorite mines: mainly distributed in Suichang County and Longquan City, followed by Jinyun, Yunhe, qingtian county and Liandu. There are three known large-scale deposits, namely Hushan in Suichang, Huangshayao in Longquan and Ba Du. The proven resource reserves (ore quantity) are 654.38+03.639 million tons, accounting for more than 90% of the total fluorite reserves in the city. It is the main fluorite producing area in our province.

Pyrophyllite: mainly distributed in qingtian county, followed by Yunhe County, Longquan City and Jingning County, characterized by excellent quality, and the proven resource reserve (ore quantity) is 23.996 million tons.

Kaolin and porcelain clay: Kaolin is mainly distributed in Songyang and qingtian county. The ore is mainly of medium and low grade, but the content of impurities such as iron and titanium is low. Porcelain clay is mainly distributed in Longquan City and Songyang County.

Granite (stone): rich in resources, more than 40 varieties have been found. At present, there are 12 varieties that have been used as decorative stones, among which Longquan Red, Qingtian Grey and Suichang Xishihong are the dominant varieties.

Tuff: Mesozoic volcanic rocks widely exposed in the city are ideal building stones and stone materials, and are rich in resources. The rhyolitic tuff in Jinyun County is mixed with pebbles and glass chips. The so-called "strip stone" is a masterpiece of garden craft stone carving, and the proven tuff resource reserve for building is 4,654,380+057,500 cubic meters.

Purple sand, potash feldspar and diopside are important raw materials for building ceramics. Purple clay is distributed in most counties (cities). Potash feldspar deposits are mainly distributed in Qingyuan, Suichang, Jingning and qingyuan county. Kunkou diopside deposit in Suichang is a large deposit with high ore grade and good mining conditions (according to the data of the Provincial Geological Exploration Institute) found in our province.

Mineral water: found in Qingtian, Liandu, Jinyun, Yunhe and Longquan counties (cities). The mineral water in southern qingtian county and Liandu Baiqiao was identified as high-quality natural mineral water by the former Ministry of Geology and Mineral Resources.

Building yellow sand: mainly distributed in Oujiang River system, rich in resources and excellent in sand quality.

By the end of 1999, the theoretical potential value of solid mineral resources in Lishui City was 67.22 billion yuan, including 3.773 billion yuan for metal minerals and 63.45 billion yuan for non-metal minerals. Based on the reserves of metal and non-metal mineral resources (excluding mineral water, building stones, yellow sand and other resources) recognized by the geological department of Lishui City, according to the potential value calculation method stipulated by the former Ministry of Geology and Mineral Resources, the city can use the potential value of solid mineral resources.
