| 中文摘要:我国钨矿床类型主要有斑岩型钨矿、矽卡岩型钨矿、云英岩型钨矿、石英脉型钨矿、蚀变花岗岩型钨矿、砂钨矿和其他类型钨矿。其中, 矽卡岩型钨矿和石英脉型钨矿是主要矿床类型。本文编制了中国钨矿空间分布及开发利用现状图, 共划分出13个成钨区带。我国钨矿具有广泛展布且局部集中的特点, 大中型矿区及白钨矿矿石类型资源储量占主导。我国钨矿床共(伴)生组分多、综合利用价值大, 但富矿少、贫矿多。钨矿是我国优势的矿产资源, 我国是世界上最大的钨生产国和供应国, 钨年产量占世界年产量的81%。我国钨产业链覆盖完整, 前端和中端具有明显优势, 高性能、高精度的高档硬质合金仍依赖国外进口。 |

| Abstract:Tungsten deposits in China can be classified into seven major types: porphyry-, skarn-, greisen-, quartz-vein-, altered granite-type tungsten deposits, sand tungsten deposits and other types of tungsten deposits. Among these types, skarn- and quartz-vein-type tungsten deposits are the most dominant. This study compiles the spatial distribution, development, and utilization of tungsten deposits in China. Tungsten deposits are divided into 13 metallogenic belts (regions). Tungsten deposit in China is characterized by widespread distribution with localized concentrations. Tungsten resources and reserves are dominated by large- and medium-sized ore fields and scheelite ores. Many paragenetic and associated components of tungsten deposits have significant comprehensive utilization value in China. There are few rich tungsten ores, while many are of poor quality. Tungsten deposits are the dominant mineral resource in China, which is the world’s largest producer and exporter of tungsten in the world. China’s annual output of tungsten accounts for 81% of the world’s annual output. The tungsten industry chain is integrated in China, with clear advantages in the front end and the middle ends on a global scale. However, the high-quality hard alloys with high performance and precision rely on imports. |
