Aminpro increased copper recovery in 8 percentage points

Aminpro performed column leaching tests for Antilla mining project, owned by Panoro Minerals.

Antilla project considers leaching over 117 Mton of secondary copper sulfides. Previous tests carried out by the company showed copper recoveries of 72,5% in 200 days of processing.

Aminpro engineers managed to obtain copper recoveries close to 80% in just 150 days of column leaching.

The President & CEO of Antilla project, Luquman Shaheen, was happy with our results:

“The results of the column-leaching experimental programme have shown a significative growth potential for the economy of Antila project”

These results were highlighted by the specialised press in Peru, as can be seen in this magazine article of  Rumbo Minero.

Visita Virginia Tech

Virginia Tech visited Aminpro

A delegation of 23 students from Virginia Tech, USA, visited Aminpro. The students were in Chile visiting several mining operations and similar companies. The visit to our facilities aimed to teach the students about the role that metallurgical laboratories and consulting companies play in the mining industry.

During their visit, they were received by Roger Amelunxen, Director of Aminpro. The students were able to visit every corner of our laboratory, pilot plant and engineering rooms, where they could ask questions to our engineers and learn about our work.

The visit, part of the Rising Sophomore Abroad Program, allowed the students to have a close look at the different processes of sample preparation, milling and flotation, learn about the traceability within our laboratory and the utility of the experimental data for modelling and plant optimization.

Alex Carvajal, CEO of Aminpro, was glad about the success of this international visit and is excited about receiving more institutions, national and international.

“We are a research and development company, and as such, attracting young and talented students is a key challenge for the development and growth of our team. We hope to receive more and more students from different careers close to mining and metallurgy, so they can learn more about how their theoretical knowledge is applied every day in the industry”.
