Kinetic Analysis of Thermal Decomposition Process of Emulsion Explosive Matrix in the Presence of Sulfide Ores

This study aims to characterize the whole reaction process of (i) emulsion explosive matrix and sulfide ores, (ii) ammonium nitrate pyrite by thermodynamics analysis method. A series experiments were carried out at atmospheric pressure from 25 °C 350 four heating rates (3, 5, 10, 15 K/min) Coats–Redfern method was applied calculate apparent activation energy samples different rates. The results show that thermogravimetric (TG) curve ores can be divided into stages: water evaporation stage, dynamic balance thermal decomposition extinguishment stage. However, burnout ignition temperature (T0) maximum peak (Tm) increased with rate, but shape TG/DTG (Derivative Thermogravimetric) not affected. is similar nitrate. stability decreases when are added. By contrast, added, more significantly.
