The flotation of carbon precipitated from carbon-saturated iron melt has been studied as a function of temperature drop, cooling rate, stirring and sulfur content in the metal. Under the experimental conditions such as temperature (1 450°C), temperature drop (50 - 240°C) and cooling rate (14.6-150°C/h), the amount of carbon floated to the top of the metal phase increased with increasing the degree of temperature drop and decreasing the cooling rate. The rate of flotation for the flaky-type graphite (Kish graphite) was faster than that for sphere-type precipitated carbon. The rate of flotation was accelerated by stirring and increased by the addition of sulfur.
