An investigation into the cementation of iron chloride from a zinc-chloride melt at 400 C has been carried out with zinc powder. The variables studies include preparation of the chloride melt and the amount of zinc added. The effect of lead, copper, and cadmium on cementation of iron has also been investigated. According to the results, it is possible to reduce the iron concentration in zinc-chloride melts to 20 ppm with a small excess of zinc. The preparation of the melt proved to be very important. Insufficient purification of the melt with respect to oxides, hydroxides, and water resulted in a low reaction rate and high residual iron concentration.
