SUPER CLEAN COAL PRODUCTION WITH ORGANIC REAGENTS FROM SLIME COAL

2022
In this study, it was aimed to produce super clean coal from Zonguldak slime coal with 29.67% ash with a completely organic process. For this purpose, slime coal was first enriched by flotation, and then super clean coal was produced by leaching with organic acids. Only organic consumables were used in laboratory-scale studies. In this way, super clean
