摘要： An object of the present invention is to provide a settling separation process for a neutralized slurry in which a neutralization step is efficiently performed for a leachate obtained by the leaching of nickel and cobalt from a nickel oxide ore, and further a neutralized precipitate obtained by precipitation of impurity components can effectively be separated and removed while inhibiting the filtration failure; and to provide a hydrometallurgical process for a nickel oxide ore, in which the above process is applied. In the present invention, a neutralization step is performed by using a magnesium oxide for a leachate obtained by the leaching of nickel and cobalt from a nickel oxide ore to obtain a neutralized slurry, and a neutralized precipitate is separated and removed by the addition of a cationic flocculant into the neutralized slurry.

摘要： The object of the present invention is to provide a method for producing an ore slurry that can suppress a rise in the viscosity of the ore slurry and consequently prevent a failure in transporting the slurry, and also to provide a metal refining method utilizing such a slurry producing method. The present invention includes: a pulverizing/classifying step S1 of pulverizing raw material ores and classifying the resulting ores at a predetermined classifying point so that oversized ore particles are removed so as to obtain a coarse ore slurry composed of undersized ore particles; a grain size measuring step S2 of measuring the grain size of the resulting coarse ore slurry; and an ore slurry condensing step S3 of loading the coarse ore slurry to a solid-liquid separation device and separating and removing moisture contained in the coarse ore slurry therefrom so as to condense ore components, and in this method, in the case when the grain size measured in the grain size measuring step S2 is lower than a predetermined value, one portion of the oversized ore particles that have been removed in the pulverizing/classifying step S1 is loaded and added to the solid-liquid separation device.

摘要： Provided is a wastewater treatment method for selectively removing manganese from sulfuric acid acidified wastewater containing aluminum, magnesium, and manganese. The wastewater treatment method is to control precipitation of magnesium from the sulfuric acid acidified wastewater containing aluminum, magnesium, and manganeseso as to obtain demanganized wastewater, through a step wherein an acid or an alkali is added to sulfuric acid acidified wastewater to adjust pH to not less than 4.0 and not more than 6.0, whereby the sulfuric acid acidified wastewater is separated into a dealuminized solution and an aluminum precipitate; a step wherein a slurrying solution is added to the aluminum precipitate to form a slurry, then an alkali is added to adjust pH to not less than 9.0 and not more than 9.5, whereby an pH-adjusted aluminum precipitate slurry is formed; a step wherein an alkali is added to the dealuminized solution to adjust pH to not less than 8.0 and not more than 9.0, then an oxidizing agent is added to perform oxidation neutralization, whereby an oxidized and neutralized slurry is formed; and a step wherein the aluminum precipitate slurry and the oxidized and neutralized slurry are solid-liquid separated.
