"The reactions that occur in the metallurgy of zinc are in general well known as to the end results obtained. The zinc smelter desires a maximum recovery in a minimum time. There are certain factors that govern the fulfillment of this desire. The most important of these are TEMPERATURE, TIME, KIND OF REDUCTION MATERIAL, and THE NATURE OF THE ORE. There is much data available as to the temperatures at which these reactions go on and also there is obtainable some information as to the speed with which these reactions progress, particularly as to the length of time required for the commercial distillation. All of this information however is to a certain degree disconnected and to some extent contradictory. the lack of information particularly true as regards the time factor and the completeness of reaction at various temperatures under known conditions. The four points mentioned above, TIME, TEMPERATURE, KIND OF REDUCTION MATERIAL, and NATURE OF THE ORE are of vital importance to the zinc metallurgist for upon these factors hinge not only the capacity of his plant, because of the speed of distillation, but, also, the recovery of values" – Statement of the Problem, p. 1.
