Froth floatation process is employed to enrich which type of ores?

Explanation

**Step-by-Step Solution:**

1. **Understanding Froth Flotation Process**: The froth flotation process is a method used to separate hydrophobic materials from hydrophilic ones. It is commonly used in the mining industry to concentrate ores.

2. **Identifying the Type of Ores**: The froth flotation process is particularly effective for sulfide ores. These ores contain metal sulfides, which are often less dense and can be separated from the gangue (the unwanted material).

3. **Example of Ores**: One of the primary examples of ores that are enriched using the froth flotation process is zinc sulfide ores. A specific example of this is zinc blende (also known as sphalerite), which is primarily composed of zinc sulfide (ZnS).
