Copper Cementation System for Small Scale Mining

Aug 17, 2017  The conversion of copper to cement copper was 67.7 percent, and the conversion of the ferric iron to ferrous iron was 71.6 percent. Thus, it appears that reactions 1 and 2 proceed simultaneously and at essentially the same rate when copper and Fe+3 ions are present in about the same concentrations. Cement Copper
