- •
A novel and efficient leaching agent was proposed to treat the low grade zinc oxide ores.
- •
The high zinc extraction and low iron extraction was obtained by controlling a suitable nitrilotriacetic acid concentration.
- •
The leaching agent was regenerated by adjusting the pH of the leaching solution.
