Lustros commences production at plant in Chile

LUSTROS, INC. announced that its subsidiary Sulfatos Chile SA has completed all the processes necessary to generate Pregnant Leaching Solution (PLS), the final step before crystallization in the manufacturing of Food-Grade Copper Sulfate. The PLS accumulates in large pools where it will concentrate for a short period before it is pumped into the company’s state-of-the-art crystallization plant and converted into 99% pure, Food-Grade Copper Sulfate Pentahydrate.

The process starts with mineral extracted from the company’s Anica copper mine. This mineral is then crushed to 0.25 inch pellets at its crushing facility and transported to the leaching pads, where it is irrigated with a mixture of sulfuric acid and water to create a solution with a heavy concentration of copper. The plant utilizes solvent by extraction technology to separate the copper from the liquid solution before it is purified and crystallized to very strict specifications.

Bill Farley, CEO and Chairman of Lustros, Inc., commented, “I am pleased that progress is continuing and that we’ve reached this important milestone. We will first be in pilot production and then look forward to a sales program in the near future.”

“This is a moment of celebration for our employees and all other people involved in the project. After 30 months and over $10 million invested, our world class facility in Chile is beginning to show tangible rewards for our efforts,” said Gonzalo Troncoso, President of Lustros, Inc. and CEO of Lustros Chile SpA.
