Answer

To answer the question "The impurities present in the ore is called," we can follow these steps:

### Step 1: Understand the context of the question
The question is asking about the impurities found in ores, which are naturally occurring solid materials from which a metal or valuable mineral can be extracted.

**Hint:** Think about the terminology used in metallurgy and what terms are associated with ores.

### Step 2: Identify the relevant terms
In metallurgy, there are several terms that are commonly used:
- **Flux:** A substance added to molten metal to help remove impurities.
- **Alloy:** A mixture of two or more metals.
- **Slag:** A by-product formed from the impurities after the extraction of metal.
- **Gangue:** The term specifically used for the impurities present in the ore itself.

**Hint:** Recall the definitions of these terms and see which one directly refers to impurities in ores.

### Step 3: Analyze the options
From the definitions:
- **Flux** is not the impurities but helps in removing them.
- **Alloy** is a mixture and does not refer to impurities.
- **Slag** is a by-product of the smelting process, not the impurities in the ore.
- **Gangue** is defined as the impurities present in the ore.

**Hint:** Eliminate the options that do not refer to impurities and focus on the one that does.

### Step 4: Conclusion
The correct answer to the question is **Gangue**, as it specifically refers to the impurities found in the ore.

**Final Answer:** The impurities present in the ore are called **Gangue**.
