CYANIDE PRODUCTION AND ACCUMULATION SYSTEM BY USING BACTERIUM AND METHOD FOR RECOVERING PLATINUM GROUP METALS FROM SPENT CATALYST OF VEHICLE USING SAME

Номер: KR1020150098308A
Автор: SHIN, DO YUN, KIM, BYUNG SU, JEONG, JIN KI, LEE, JAE CHUN, JUNG, CHAN HYUK
Принадлежит:

The present invention is to develop a cyanide production and accumulation system by using a bacterium, and relates to a technique of recovering platinum group metals from a spent catalyst of a vehicle using a cyanide solution produced using the system. By using the cyanide production and accumulation system developed in the present study, biological cyanide production can be increased. Since the produced cyanide solution is a cyanide solution not including a bacterium, leaching kinetics can be prevented from being reduced by covering the surface of an ore or a waste by a membrane of the bacterium, and cyanide can be produced by maintaining a pH of 10.5 to 11, which is the most productive in the cyanizing process. In addition, cyanide is microbiologically produced, which is relatively safe and has a small impact on the environment. When a biologically produced cyanide solution is compared with a chemical cyanide solution using the system developed in the present study, it is confirmed that ...
