The advantage of wet treatment of sulfide ore is that it does not produce sulfur dioxide, which can avoid air pollution. If it produces simple sulfur, it is easier to transport and store than sulfuric acid. Slag leaching residue intractable than the fire wet, but to provide concentrate for Fire beneficiation plants have similar problems. Recycling iron hydrometallurgical copper is a big problem, sodium jarosite is facing great pressure discharge should be studied into the iron slag iron feedstock. The wet process should do the following to become an environmentally friendly process:

1. Use a non-toxic leachant;

2. Extract all valuable metals from the ore;

3. All kinds of solutions in the process are recycled or discharged after being treated to the standard;

4. Produce stable leaching slag, which will not produce toxic substances due to rainwater leaching;

5. Select a reliable slag yard to ensure that the residual liquid in the slag does not penetrate into the ground;

6. Re-vegetation of slag heap.
