Meaning
The kanji 鉱 (鉱) primarily means 'ore,' 'mineral,' or 'mine.' It is an important character for understanding discussions about natural resources, geology, and industries related to the extraction and processing of materials from the earth. Its meaning is visually communicated through a fascinating blend of components.
Its origin is revealed by its two main parts. The left side, 金 (金), is the radical, meaning 'metal' or 'gold.' This radical is commonly found in kanji related to metals, money, or anything metallic. Its presence immediately hints at the material aspect of 鉱: its connection to valuable substances found within the earth. The right side, 広 (広), means 'wide' or 'spacious.' While not directly related to minerals, in the context of 鉱, it primarily serves a phonetic role, providing the 'kō' sound. However, one could also interpret it as subtly suggesting the vastness or wide areas where minerals are found, or even the extensive process of mining. Therefore, 鉱 can be conceptualized as 'metal (or mineral) in wide (or extensive) deposits.' This kanji consists of 13 strokes and is taught in the 5th grade in Japanese elementary schools. Its JLPT classification places it at N2, highlighting its importance for intermediate Japanese learners.
Readings
On'yomi (音読み) — Chinese-derived readings
The primary On'yomi reading for 鉱 is コウ (kō). This reading is derived from Chinese and is primarily used in compound words, especially in scientific, industrial, or geological terms. This is the most common way to encounter 鉱 in formal contexts.
- 鉱山 (kōzan) — mine; mining mountain. This refers to a site where minerals are extracted.
- 鉱石 (kōseki) — ore; mineral rock. This term denotes rock containing valuable minerals.
- 鉱業 (kōgyō) — mining industry. This encompasses all activities related to extracting minerals.
Kun'yomi (訓読み) — Native Japanese readings
The main Kun'yomi reading for 鉱 is あらがね (aragane). This reading is much less common in modern Japanese compared to its On'yomi. あらがね specifically refers to 'unwrought metal' or 'raw metal'—metal in its crude, unrefined state, fresh from the earth before it has been processed. While historically more prevalent, its usage is now mostly found in specific, often archaic, contexts, or in more poetic descriptions of raw materials. It is more commonly found in literature or specialized texts than in everyday conversation.
- 荒金 (aragane) — raw metal; unrefined ore. This word directly uses the kun'yomi to describe metal that has not yet been purified.
- 粗金 (aragane) — another way to write あらがね with the same meaning, emphasizing its coarse or rough nature.

Memory Tip
To remember 鉱 (鉱), think of its components: 金 (金) meaning 'metal' or 'gold,' and 広 (広) meaning 'wide.' Imagine a vast, wide expanse of land, perhaps a large mountain range, where precious 'metals' or 'minerals' are abundantly found deep within the earth. The '金' radical on the left side is a strong visual cue for metallic substances, and the '広' on the right helps you recall the 'kō' sound and the idea of wide, open mines. So, it's 'metal' found 'widely' in the ground, leading to 'ore,' 'mineral,' or 'mine.' This visual story helps connect the kanji's visual form to its meaning and pronunciation.
