Which is not correctly matched :

Options

A. Spiegleisan `" " : Mn +Fe+C`
B. Dow's sea water process `" " : Ca(OH)_(2)`
C. Parke's process `" " : Ag`
D. Liquation `" " : ` spelter (Impure Zn)

Explanation

To determine which option is not correctly matched, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding the Options**:
- A. Specklesian
- B. Dose seawater process
- C. Parkes process
- D. Liquation

2. **Analyzing Each Option**:
- **A. Specklesian**: This term is likely referring to "spelter," which is a term for zinc obtained from ores. It is correctly matched as it relates to the production of zinc.
- **B. Dose seawater process**: This option seems to be a typographical error. The correct term is likely the "seawater process," which is used for extracting certain metals. This option needs clarification but is generally associated with metal extraction.
- **C. Parkes process**: This is a well-known method for refining silver from lead. It is correctly matched.
- **D. Liquation**: This is a metallurgical process used to separate metals from their ores based on their melting points. However, the description provided in the transcript indicates that liquation is not the method used to obtain pure zinc.

3. **Conclusion**:
- After analyzing the options, it is clear that option D, "Liquation," is not correctly matched in the context of obtaining pure zinc. The transcript indicates that pure zinc is obtained through distillation or electrolysis, not liquation.

### Final Answer:
**D. Liquation is not correctly matched.**
