DHE Minerals is equipped with Design-Expert software, Version 13

January 29, 2021

It is statistical software from Stat-Ease Inc. (USA), which is primarily devoted to conducting the design of experiments (DOE). 

Experimentation in a one-factor-at-a-time (OFAT) manner is ineffective and sometimes delivers misleading results.


DOE requires only a minimal number of runs to study several factors and identify the variables' interactions. By this method, you make changes to input variables of the process to observe the output's effects. It leads you to understand the process enormously, thus enhancing the product quality (i.e., metal grade and recovery), lowering costs, and increasing profits!
