Abstract

Conventional converting of nickel-containing copper mattes in Peirce–Smith horizontal converters does not conform with the current environmental regulations. A global trend is to change over from conventional batch converting to a continuous converting process producing running slags. The main purpose of the continuous matte converting process is to produce commercial blister copper that would not require oxidation during further anode refining. To minimize the risks of obtaining off-grade blister copper, the Norilsk Nickel Continuous Converting of Copper Nickel-Containing Mattes Project provides for granulation and rapid determination of the composition of converter matte using an on-stream analyzer. Currently, the matte granulation process has not been studied adequately. The objective of this paper is to study the granulation of copper–nickel mattes of variant composition under various process conditions.
The effect of the granulated matte composition on water pH has been studied. Noticeable acidification of water used for melt granulation has been found out, which is probably due to the formation of soluble sulfates of non-ferrous metals and sulfuric acid. To minimize the risk of equipment wear, a method for neutralizing the process water with alkali in the granulation unit has been proposed.
The time of accumulation of sodium sulfate to the solubility limit in the closed water supply cycle of the granulation unit has been determined based on the composition of granulated mattes. DTA and TGA data for granulated matte samples indicate a decrease in the equivalent diameter of matte granules with increase in the degree of superheating above the liquidus temperature. It has been established that not only the superheating of the melt, but also the pressure head of granulation water–air jet affects the degree of dispergation of the melt.
