  • Solved: A copper smelting process is supposed to reduce ...

    A copper smelting process is supposed to reduce the arsenic content of the copper to less than 1000 ppm. Let μ denote the mean arsenic content for copper treated by this process, and assume that the standard deviation of arsenic content is α = 100 ppm. The sample mean arsenic content of 75 copper specimens will be computed, and the null hypothesis H 0: > 1000 will be tested against the ...

  • Copper Smelting Chemistry Tutorial - AUS-e-TUTE

    Any copper(I) oxide present will be converted into copper(I) sulfide during the smelting process because copper has a higher affinity for sulfur than it does for oxygen. for example: Cu 2 O + FeS → Cu 2 S + FeO. Impurities form a slag which floats on the surface and is easily removed. One of the reactions to remove iron impurities is shown below:
