The paper presents the results of the analysis the remelting processes of the copper and its alloys. The evaluation of the amount of hydrogen with oxygen, cool and its compositions in the melting atmosphere which is constituted in these conditions has been carried out. It proves there is a big discrepancy in the opinions on the structure and the basic features of hydrogen influence in to the slag and in to the copper alloys as well as the essence of their interaction with the oxygen and cool. It is also stated that the analytical methods, which are used nowadays describe chosen features of the slag, cannot be regarded as a base for estimation of their refining abilities in the real, multifeatural (atmosphere-slag-metal) metallurgical system.
