鎢礦大别有兩大類,一为黑鎢,一为白鎢。中國鎢礦生產,直至目前为止,90％以上是採自黑钨,歐美及其他国家在第一次世界大战以後,白鎢生產已逐年上升,隨着生產技術的進步,至第二次世界大戰前後,白鎢產量,已大大超過了黑钨產量。中国在解放後幾年来,也陸續發現了不少白鎢礦區,在這些礦區中以矽卡岩型礦床,規模最大,因此這種類型的礦床可能成为工業上最主要的礦床類型,從而使白鎢礦床成為最主要的勘探對象。现僅根據我隊年来的工作經驗,對矽卡岩型白鎢礦床的地質條件及找矿勘探方法分述如下:
There are two major types of tungsten ore Dabie, one for the black tungsten, a white tungsten. China’s tungsten ore production, so far, more than 90% is collected from black tungsten, Europe and the United States and other countries after the First World War, the production of scheelite has increased year by year, with the improvement of production technology, to World War II Before and after, the production of white tungsten has greatly exceeded the production of black tungsten. In the few years since the liberation, many scheelite areas have also been discovered in China, where skarn deposits are the largest in these mines, so this type of deposit may become the most important deposit type in the industry, Tungsten deposits become the most important exploration target. Based only on my team’s work experience for the past few years, the geological conditions of skarn-type scheelite deposits and prospecting methods are described as follows:
