उत्तर
The rocky material found with ores is called gangue.
Explanation:
Gangue refers to the commercially worthless rocky, earthy, or sandy material that surrounds and is closely mixed with a desired mineral or ore in a deposit. Common examples include quartz, silica, feldspar, and various limestone compounds that must be separated during mining. Processing methods such as froth flotation or magnetic separation are used to remove this waste material, allowing the pure metal to be successfully extracted.
