A concise historical review is given of the Overpelt plant and the general principles of zinc hydrometallurgy are briefly outlined, together with a description of the new electrolytic zinc plant ore roasting process and, more particularly, the original Overpelt roasting process.
A detailed description of the flowsheet of the zinc elec-trowinning plant, with an annual capacity of 100,000 t, successfully put into operation in May 1974, is given. The treatment of the residues is performed following the goethite process; the purification is continuous in two steps; the tankhouse is equipped with cells containing jumbo cathodes; the handling and stripping of the cathodes is fully mechanized.
Concluding the description, some metallurgical and other features of the project are explained in detail.
