Abstract
Oxidation process of iron sulfides was observed by installation of oxidation experiment. Oxidation process of iron sulfide can be divided into three stages: surface layer self-heating period, incubative period and accelerative oxidation period. Heat gathering was the key factors for iron sulfide self-ignite. Effects of oil, water content and sulfur on heat gathering were explored using oxidation experiment installation. The results show that oil has complicate effect on self-ignite of iron sulfide. Water content can prevent iron sulfide from oxidizing. Sulfur has a little effect on initial stages of self-ignite, while in the final stage it can be as external heat source.
