The gold ore from Kushikino-mine contains mainly electrum, pyrargyrite and argentite, wheres these minerals are not suitable for ordinary cyanidation process.
We conducted some studies on this ore which was summerized as follows;
1. More effecive cyanidation process.
2. Re-treatment of the cyanide tailing by flotation or gravity-seperation.
3. Flotation followed by cyanidation process.
After all, we had reached to the conclusion that the last process was the most preferable one, and our flotation plant was put into operation in July, 1954.
