It is difficult to filter-press the leachate containing copper when its pH is 2.0. Do any of you have any solutions for this issue? Thank you!
What is contained in the liquid extracted from any raw material? Is it the difficulty in separating solids from liquids after leaching, or is it the raffinate?
The leachate is an NISO4 solution, and we want to extract the copper from it; at a pH of 2 after leaching, it is difficult to carry out pressure filtration
Check the iron and soluble silicon content inside, then examine the filter cloth model; try adding some filter aid； The pH can also be lowered to around 1.5.
Is the filter cloth model appropriate? Model 758 is generally fine. The iron content in the solution before filtration should not be too high, as this can affect the extraction process; generally, a pH level of 1.5 or 3.5 is suitable for filtration
It depends on the specific situation; adding something like lime might help.
