INTERNATIONAL GRINDING AND TECHNOLOGY CONGRESS

17 & 18 JULY 2025

INTRODUCTION

Grinding is one of the most critical operations in the mining and metallurgical industry and requires the most energy. At this congress, we will bring together experts, researchers, and professionals to share knowledge, discuss innovations, and explore new technologies contributing to more efficient and sustainable mining.

The IGTC 2025 will take place on July 17 and 18 at the Sheraton Hotel in the city of Chihuahua, Mexico. During the event, we will address key topics such as:

✔ Design and optimization of crushing and grinding circuits
✔ Innovation in grinding equipment and media
✔ Process control, simulation, and modeling
✔ Optimization of mineral processing plants
✔ Mill linings and particle classification
✔ Applied research and education in metallurgy

Don’t miss this opportunity to connect, collaborate, and lead the transformation of the mineral processing industry.

It is an honor to welcome you to this space, where we share our passion and commitment to excellence in mineral processing. For over 26 years, I have dedicated my career to the development and innovation of this industry, refining fundamental techniques such as crushing, grinding, flotation, leaching, and solid/liquid separation.

 

My academic background includes a Ph.D. in Mineral Engineering from the University of Queensland, Australia (JKMRC), where I had the opportunity to specialize in mathematical modeling applied to mining processes and contribute to the validation of mathematical models for the commercial simulator JKSimMet.

 

Throughout my career, I have worked on the comprehensive optimization of mining and metallurgical operations under the mine-to-mill approach. My experience combines research and teaching with practical application in major international mining operations such as Minera Fresnillo, Peñasquito, Grupo México, Cadia Mine, and Mount Isa Mines, among many others.

 

My achievements include significantly reducing molybdenum production costs, pioneering the implementation of large-diameter cyclones in beneficiation plants, and successfully developing a beneficiation plant with an SABC grinding circuit for the sequential flotation of copper and zinc. I am currently involved in commissioning this plant, ensuring its optimal performance.

 

Today, as President of the first International Grinding and Technology Congress (IGTC), I continue to promote continuous improvement strategies in the mining industry. I apply tools such as Lean Manufacturing to optimize processes and eliminate production bottlenecks. I firmly believe that innovation and knowledge are the keys to the sector’s sustainable growth, and I am proud to be part of this exciting journey toward the future of mining.

Sincerely,

Dr. Juan Luis Reyes Bahena

President
