To provide a method for treating carbon fine particles, by which energy efficiency is good, lead can be effectively separated and lead content in carbon fuel can be reduced and to provide a method for producing the carbon fuel from the carbon fine particles, when the carbon fine particles contained in gas produced when performing reductive heat treatment of waste, are effectively used.
In the method for treating the carbon fine particles produced when performing reductive heat treatment of the waste, produced gas including the carbon fine particles is washed with a washing liquid to obtain carbon fine particle-containing washing water. Then the fine particle-containing washing water is subjected to solid-liquid separation or solid condensation separation to take out or extract solid or condensed liquid including the carbon fine particles. Oil is added to a dispersion liquid where the solid or the condensed liquid including the carbon fine particles is dispersed and then stirring is carried out. Thereby the carbon fine particles are granulated in the liquid to form a carbon granulated body and then the carbon granulated body is taken out.
