Ecperimental study of melting within Fe_1-xS—NaCl and Fe_1-xS—H_2O—HCl systems

摘要

The series of experiments on the pyrrhotite meltingin the Fe_1-xS—H_2O—HCl systems at 1000-1150degC and1atm and in the Fe_1-xS—H_2O—HCl systems at 1000-1150degC and 1000 atm were carried out. Obtained resultsdemonstrate almost complete inmissibility in the Fe_1-xS—H_2O—HCl system. The NaCl solubility in pyrrhotite does notexceed of 1 wt% while the pyrrhotite solubility in halite is below0.7wt%. in both cases, the solubility decreases with temperature.The addition of HCl does not affect the solidus temperature ofmonosulfide which remains the reveal a substantial effect of NaCland HCl on the melting temperature of pyrrhotide.
