The New Dense-Medium Coal Preparation Plant of Horonai Colliery

Abstract

In this article the outline of the new coal preparation plant completed in August 1960 at Horonai Colliery. Hokkaido, is described. The plant consists of main and auxiliary Drewboy dense-medium separators imported from PIC, France, having the capacity of 250 tons and 110 tons per hour respectively, together with its medium reclamation system. It is expected that the plant will produce approximately 4000 tons of cleaned coal per day by 1963.
