Title:
亜鉛浸出工程における希少金属回収方法
Document Type and Number:
Japanese Patent JP5334592
Kind Code:
B2
Abstract:
Sulphidic zinc concentrate usually also includes small amounts of rare metals such as indium and gallium. If the content of these metals in the raw material is sufficiently high, their recovery may be economically worthwhile. In the method according to the invention the recovery of indium and other desirable rare metals takes place in a zinc leaching process, in which at least part of the sulphidic concentrate is leached directly without roasting.
