Apr 01, 2014 Sodium hydroxide (NaOH) has to be used as the pH regulator, and using sodium carbonate for adjusting the pH of the pulp in zinc oxide flotation can decrease the quantum of mineral recovery. This phenomenon can be argued based on the dominant species diagram for the Na 2 CO 3 –ZnCO 3 system, that is at a pH of around 11, using extra Na 2 CO 3

Zinc Wikipedia

Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a silvery-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table.In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn 2+ and Mg 2+ ions
