Wastewater from gold recovery contains strong acids and heavy metals. Indiscriminate discharge can corrode building pipe line, and it is also toxic to the environment.
Therefore, wastewater must be treated before it can be discharged. I use chemical displacement reactions in the film to swap precious and base metal bodies for iron.
Then I use NaHO to separate liquid from iron.
Neutralized liquid can be discharged and Iron slag is discarded directly.
