27.04.2018· Gold smelting Flux Lowers Smelting point: If the ore from which gold is to be separated out contains elements and impurities with a high melting point. The process becomes highly energy intensive as high temperatures are required to get the mixture melted down. The addition of flux provides a very desirable solution to this problem. The chemistry of the chemicals that constitute gold smelting

zinc carbonate ore was not shipped from it until 1913. On July 23, 1914, the writer visited the two mines, the Cliff and Hidden Treas- ^ ure, that were shipping zinc carbonate ore. The output of this ore ^ from each mine was small, but the deposits presented some very interesting features, the principal of which were the marked lamellar structure of the zinc carbonate in contrast to that in
