2021-11-28  The recovery of zinc with this level of CaCO3 is possible; however it is economically viable we cannot say. For that truly do the calculations of zinc cleaning process, however as you will not have mining costs but the extraction of the sludge may help us end costs. Another idea is to use this product for CaCO3 as a soil amendment or cement.
