Case Study: Met‑Mex Peñoles cuts costly gold & silver losses and avoids pilot trials with Palisade DecisionTools Suite

Met-Mex Peñoles - Customer Case Study

Met‑Mex Peñoles, the world’s largest refiner of silver and Mexico’s largest refiner of gold, faced the challenge of optimizing its refining processes without wasting costly precious metals on risky pilot projects. To support Six Sigma Design of Experiments and avoid expensive trial runs, the company turned to Palisade’s DecisionTools Suite (including @RISK and TopRank) to model and analyze process variability and material losses.

Using Palisade’s DecisionTools Suite, Peñoles built detailed Six Sigma simulations that incorporate physical error measurements, equipment tolerances, random processing errors and precise cost analyses; @RISK distribution fitting and TopRank improved insight and visualization. The Palisade solution let the company answer difficult process‑design questions without running many pilot trials, cut the number of costly experiments, and minimize gold and silver losses while improving communication and decision making.
