The minerals include the native metals copper and gold, and many sulfides, oxides, and hydroxides. Minerals in these groups are generally good ore minerals because they contain relatively large amounts of the desired elements.

Find the incorrect option:a)Minerals are usually formed in "ores".b)T...
Explanation:
The incorrect option is option C: The mineral content of the ore must be in sufficient concentration to make its extraction commercially viable.
Reasoning:
- Minerals are usually formed in "ores": Ores are naturally occurring rocks or minerals that contain a valuable substance that can be extracted for profit. Minerals are often found in ores and are extracted through mining and processing.
- The term 'ore' is used to describe an accumulation of any mineral mixed with other elements: Ores can contain a mixture of minerals and other elements. For example, iron ore contains iron mixed with other elements such as oxygen and sulfur.
- The type of formation or structure in which they are found determines the relative ease with which mineral ores may be mined: The geological formation or structure where mineral ores are found can affect the ease of mining. For example, ores found in shallow deposits near the surface may be easier to mine than those found deep underground.
Incorrect Option:
- The mineral content of the ore must be in sufficient concentration to make its extraction commercially viable: This statement is incorrect because the mineral content of an ore does not necessarily have to be in sufficient concentration to make its extraction commercially viable. Some ores may have low mineral concentrations but still be economically viable to mine and extract due to factors such as the demand for the mineral, the cost of extraction, and the availability of technology.
Example:
- Bauxite is an ore that contains aluminum mixed with other elements. The mineral content of bauxite is relatively low, but it is still commercially viable to extract aluminum from bauxite due to the high demand for aluminum and the availability of efficient extraction methods.
Conclusion:
The incorrect option is option C because the mineral content of an ore does not have to be in sufficient concentration to make its extraction commercially viable. Other factors such as demand, cost, and technology can also determine the commercial viability of extracting minerals from ores.
