Question

a chemical equation for the reaction between iron pyrite and oxygen

Answer 1

Hello mate:

Here is ur answer;

In the current case, iron pyrite is the fuel and atmspheric oxygen is the oxidant. This is a combustion reaction and generates iron (III) oxides. ... Typically, the pyrite ore containing up to 85% iron pyrite and 15 % inert materials reacts with excess air (up to 200% excess) to generate sulfur dioxide (SO2).
