The liquefying process and zinc oxide production process are computerized.

A lot of equipment and materials provided by national institutions and the General Bureau of the Tanchon Area Mining Industry to the project and their aid given to help settle technical problems contributed to its successful project.

Mass-production of zinc oxide and remarkable increase of actual zinc extraction rate will help radically boost the production of quality nonferrous metal.
