Ilmenite beneficiation process and a digester method

摘要

An improved digester method and apparatus particularly useful in the digestion stage of a process for the beneficiation of titaniferous iron ores and the like. A discharge nozzle is connected to a portion of the digester and the digested material is pumped from the digester via a pump connected to the discharge nozzle. In one aspect, fluid from a fluid source is passed through a portion of the discharge nozzle and into the interior of the digester for dislodging any solid-like masses prior to discharging the digested material and, in another aspect, fluid from the fluid source is passed into the discharging digested material from the digester.
