    May 15, 2018· Thermal characteristics of the limonite laterite ore types have been studied using TG / DTA. There are four endothermic peaks at 250, 646, 900, and 1023 °C with a total mass loss of %. These four peaks correspond to the XRD results on samples calcined at °C. Analysis of TG / DTA to the mixture of limonite and graphite showed two endothermic reaction peaks .
