鑛

Phono-semantic compound:

金 (쇠 금) - semantic component, indicating the metal/metallic nature.

廣 (넓을 광) - phonetic component, indicating the sound “광 / kwang”

Literally “metal + broad/expanse” but used metaphorically for “metal in the broad earth” i.e., ore/mineral deposit.

鑛石 (광석) — ore (literally “ore rock”)

原鑛 (원광) — ore; the raw mineral deposit

鑛物 (광물) — mineral

Because the character is not included in the standard “Basic Hanja for Educational Use” list for modern Korean (it is rare), usage in Korean texts often has been technical, historical, or in compound terms.

As this character denotes “ore/mineral”, it was historically relevant in contexts of mining, metallurgy, natural-resource management: e.g., in 20th century Korean constitutional discussions the term “important mines, refineries” (‘광산’ etc) appear though the exact Hanja 鑛 may or may not be used.

The variant form “礦” is used (U+7926) with the phonetic component 丱 in its archaic form.
