GONZALEZ, J. Manuel; PATINO, Francisco  e  SALINAS, Eleazar. Medición del contenido calórico de la mata de cobre (Cu₂S-FeS) usando un calorímetro de gota. Rev. Soc. Quím. Méx [online]. 2001, vol.45, n.1, pp.13-16. ISSN 0583-7693.

The purpose of this study was to find the heat content of the Cu₂S-FeS matte for evaluating the heat balance in copper converting. The heat content of some Cu₂S-FeS mattes were determined in a temperature interval from 1073 to 1473 K by using a drop calorimeter. The heat contents of 100 % FeS, 75 % FeS-25 % Cu₂S, 50 % FeS-50 % Cu₂S, 25 % FeS-75 % Cu₂S and 100 % Cu₂S at 1473 K are 1253, 1134, 1008, 879 and 756 J/g, respectively, decreasing with increasing matte grade.
