In today's mill operation, both rise of the electric power cost and lack of the land for tailing dam are serious problems. “Elimination of the gangue mineral in coarse grain sizes” can be said as an approach which solves positively the problems men-tioned above. Namely, a remarkable decrease in quantity of the gangue mineral passing a grinding circuit based on “Elimination-” brings, 1) a reduction of the electric power cost in grinding circuit, 2) a prolongation of the life of tailing dam owing to lesser formation of the slimy tailing. Moreover, by attainment of the matter mentioned above, a selling of the gangue mineral as aggregates may be expected.
In order to offer some technical informations to various trials concerned with “Elimination ”, in the second paper, this research committee has reported about the following two subjects.
1) Examples of actual operation:
Jokoku Plant (Hokkaido)
Hosokura Plant (Miyagi Pref.)
Kaneuchi Plant (Kyoto Pref.)
Yanahara Plant (Okayama Pref.)
Kuga Plant (Yamaguchi Pref.)
Kushikino Plant (Kagoshima Pref.)
2) Introduction of an important literature:
La Préconcentration (Industrie Minerale-Les Techniques, Janvier 1981)
