在日本山口县以东的(Kuga)地区发现一个有希望的钨矿床。发现两个矿化带,一个平均含钨2—3%,另一个含钨3.7%。这都比现在所开采的矿石品位高。将进一步勘探以定其储量。日本1978年钨精矿的产量为1.3191吨。
A promising tungsten deposit was discovered in the Kuga area east of Yamaguchi Prefecture in Japan. Two mineralized zones were found, one containing tungsten on average 2-3% and the other containing tungsten 3.7%. This is higher than the mineral grades currently mined. Will explore further to determine its reserves. Japan’s 1978 tungsten concentrate production was 1.3191 tons.
