The impurities associated with the ore after mining are collectively called

Options

A. Flux
B. Slag
C. Minerals
D. Gangue

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question:** The question asks about the term used to describe the impurities that are found with the ore after it has been mined.

2. **Definition of Ore:** Ore is a naturally occurring solid material from which a metal or valuable mineral can be extracted profitably. However, ores are not pure and often contain various impurities.

3. **Identification of Impurities:** After mining, the ore is still mixed with impurities that are not useful for the extraction of metals. These impurities can include various earthy materials.

4. **Terminology:** The impurities associated with the ore are collectively referred to as "gangue." Gangue consists of the unwanted materials that are extracted along with the ore.

5. **Separation Process:** The gangue is separated from the ore through a process known as the concentration of ore. This process involves various methods to remove the gangue and obtain a purer form of the ore.

6. **Further Clarification:** When gangue is combined with a substance called flux during the smelting process, it forms a byproduct known as slag. Flux is used to facilitate the removal of gangue.

7. **Final Answer:** Therefore, the impurities associated with the ore after mining are collectively called **gangue**.
