Fill in the blanks by selecting correct word/term given in the brackets.
Froth floatation process is used to concentrate __________ ores. (oxide/sulphide)

Explanation

To solve the question, we need to fill in the blank in the statement: "Froth flotation process is used to concentrate __________ ores." The options provided are "oxide" and "sulphide."

### Step-by-Step Solution:

1. **Understanding the Froth Flotation Process**: The froth flotation process is a method used in metallurgy to separate valuable minerals from their ores. It is particularly effective in concentrating certain types of ores.

2. **Identifying the Type of Ores**: The process is primarily used for the concentration of sulfide ores. Sulfide ores contain metal sulfides, which are more amenable to separation through this method.
