PROCESS FOR SEPARATING HYDROPHILIC SUBSTANCES FROM A HYDROPHOBIC MATERIAL, PROCESS FOR TREATING COAL POWDER FROM A COAL PREPARATION PLANT, AND PROCESS FOR PRODUCING METALLURGICAL QUALITY COAL AND ASH POWDER COAL

摘要

The invention relates to a process for separating hydrophilic substances from hydroformic acids. This process consists in forming an aqueous suspension of hydrophilic and hydrophilic substances, and adding to this suspension a hydrofluorocarbon.
