Abstract
The present invention relates to the technical field of resource recycling, and particularly relates to a method of recovering tin from a liquid crystal-containing indium concentrate. The method comprises processes of low-temperature baking, ball milling, alkaline roasting, adding water and leaching, filter pressing, tin extraction, founding, etc. The method of the present invention has advantages of a high direct recovery rate of tin, an easy-to-operate process, a low hardware cost, a low manufacturing cost, and being free from secondary pollution generation, etc.
IPC Classes ?
- C22B 25/06 - Obtaining tin from scrap, especially tin scrap
- C22B 25/02 - Obtaining tin by dry processes
