Dryers in the mining industry rely on various heat sources, including natural gas and propane, which are widely used but may add moisture and emissions.
In remote areas, fuel oil (diesel) is often preferred due to limited access to natural gas. Electricity mainly used in indirect dryers offers clean, emission-free heating, though it tends to be more expensive.
To enhance sustainability and lower carbon emissions, alternative fuels such as biomass, waste heat recovery, and biogas are increasingly being adopted.
The choice of energy source depends on factors like local availability, cost, environmental regulations, and operational requirements(feeco, 2017).
