Practice Question

🎉 Explanation

English Explanation

Both 選 (せん) and 鉱 (こう) are read with their standard On'yomi, forming a technical term. えんこう misreads 選. The other incorrect options add extraneous characters. The term refers to the process of separating valuable minerals from waste rock in extracted ore, improving its quality before further processing.

日本語解説

選(せん)と鉱(こう)は共に標準的な音読みで、専門用語として用いられます。えんこうは選の読み間違いです。選鉱とは、採掘された鉱石から有用な鉱物を分離し、品質を高める工程を指します。
