Recent, developments in the field of measuring and controlling techniques are playing an important role especially in mineral dressing operations, where it is greatly expected to solve many complex and dynamic factors involved.
At Taishu mine, located on the TSUSHIMA Island (130km from Fukuoka), Nagasaki Prefecture, 14, 000 metric tons of a lead-zinc-iron sulphide are is being treated monthly by means of a straight differential flotation process accompanied with a dense medium pre-concentration.
Some experiments have been made with several new techniques in order to overcome operating difficulties, e. g. fluctuation in quality and quantity of run-of-mine ore, and poor separation of marmatite from pyrrhotite, etc., but many problems are still being left unsolved. A brief description is given on important matters in relation to the rationalization of milling operation in the mine.
