Dangers of Lead-Zinc Tailings - Xinhai

Due to different ore properties and flotation process demands, pH value of slurry is different too. The pH value of lead-zinc tailings generally shows alkaline. When the pH value of slurry is alkalescence, heavy metal ions in tailings will precipitate in the form of hydroxide, which won't exceed the standard generally.
