THERMAL BEHAVIOR AND KINETICS OF SULFIDE …
Results indicate that the heating rate is an important factor affecting the thermal behavior of sulfide concentrates. The peak temperature corresponding to the maximum mass loss rate of the ore sample at different heating rates is different and the sulfide concentrates at heating rate of 5 ℃ per minute is more prone to spontaneous combustion.

Combustion and Flame: Class 8 Notes, Important Questions
Aug 10, 2021 · Types of Combustion. Combustion can be divided into three types- rapid, spontaneous and explosion. Rapid Combustion. It is a type of combustion in which the gas burns quickly and produces heat and light. When a lit matchstick is placed near a gas burner, and the gas tap is turned on, the gas instantly begins to burn, producing heat and light.
