The residues left after extracting thesilver form the source of supply for thecobalt oxide plant. In this plant thecobalt and nickel oxides are producedand shipped to England, France, UnitedStates, etc. The operations in thisdepartment are purely hydro-metallur-gical; in other words, it is a wet plant. The residues are first processed insuch a way that the metal content isrendered soluble. The next step in the
