PROBLEM TO BE SOLVED: To obtain a molded material having strengths by low compressive force from coal from which a molded material having strengths is not obtained when coal powder or coal powder mixed with another substance is compression molded. SOLUTION: The method for molding a mixture comprises mixing coal powder having≤10% or≥30% volatile matter content, which has a large amount of expansion and does not give a molded material having strengths, with coal powder having >10% and <30% volatile matter content, which has a small amount of expansion and gives a molded material having strengths in the weight ratio of≥15% and compression molding the mixture by using a roll type molding machine at≥35 kN/cm pressure between rolls and≤60 kN/cm compression force when coal powder is compression molded or coal powder is mixed with vegetable powder such as saw dust, maize stem, slaked lime as a desulfurizing agent, or the like, so as to reduce soot and SOx in flue gas during combustion and to make briquette.
