How it's used
Focuses specifically on the industrial or large scale removal of natural resources like minerals or coal. It carries a formal tone often found in news reports or historical accounts rather than everyday casual conversation. When discussing the general act of digging up the ground, other verbs like 掘 are far more common.
Examples
They extracted a lot of ore here in the past.
Has the government approved their extraction at this mine yet?
Related words
Common mistake
Avoid using this for casual digging in the garden or construction work, as it implies a systematic, commercial, or industrial process of resource extraction.
