BRIQUETTE MANUFACTURING METHOD, REDUCTIVE METAL MANUFACTURING METHOD, AND ZINC OR LEAD SEPARATION METHOD |
摘要 |
An object of the present invention is to produce briquettes that have high strength even when the amounts of binder and water used are decreased as much as possible. A method for producing briquettes that achieve this object includes a step of forming primary granules by using a powder containing a metal oxide and at least one of zinc oxide, lead oxide, and titanium oxide and a step of compressing the primary granules still containing the at least one of zinc oxide, lead oxide, and titanium oxide so as to mold the primary granules into secondary granules. |
