New leaching facilities

by InnovationLaboratoryOur company

At Aminpro we are constantly investing in the continuous improvement of our processes and facilities, in order to deliver the best service to our customers. That is why we have expanded our installed capacity to perform leaching tests at different scales.

We have new automated equipment for bottle leaching tests, with temperature, agitation, and timer control. We have also installed 30 6-meter high columns for 180-day irrigation tests.

We are currently conducting several tests of non-chloride leaching of copper ores, using 3 sets of columns in a series of 3, i.e. where the first column feeds the second column, etc. This allows us to study the behavior of the ore over long periods of time with different irrigation rates.

New geometallurgical project

by EngineeringLaboratoryOur company

Aminpro is starting a new project of test work for geometallurgy, which considers the mapping, and comminution and concentration tests to inform the geometallurgical models of our client. The project includes the mapping of 6,000 m of cores, comminutions tests, flotation and magnetic separation, as well as sedimentation tests and rheology characterization.

The project also considers the pilot testing of magnetic separation, both dry and wet,  using magnetic drums – DFA – CDA – L-8, among others.

Aminpro gave a talk on a webinar for clients in Central America

by Fairs and exhibitionsOur company

Aminpro was invited by Anminco to give a talk on a free webinar for clients in Central America. Our Laboratory Chief Engineer, Esteban Rodríguez, talked about the added value of metallurgical tests for the development and evaluation of mining projects.

Esteban

The talk was very well received by the participants, who congratulated the organisation and our company. You can find the presentation (in Spanish only) here.

Aminpro improves its Pilot Plant

by InnovationOur company

At Aminpro we have a complete pilot plant for mineral processing, including crushing, milling, flotation and thickening operations.

Our flotation cells are modified square Denver cells, with capacities ranging from 80L for the rougher stage, to 5L to the cleaner.

During 2021, we have been modifying and improving our flotation cells in order to enhance our capacity to float coarse and heavy materials, such as iron ore. These improvements entail the modification of the overflowing system and some internal designs, in order to prevent solid settlement, thus obtaining a more efficient operation.

If you want to know more about our facilities, equipment and capabilities, just contact us.

Did you know that Aminpro conducts Cobalt metallurgical tests?

by InnovationOur company

Cobalt is a relatively scarce ferromagnetic metal, mainly used in high-performance super alloys and in the glass and ceramic industries, providing a distinctive blue color. However, its importance today lies in its use for the manufacture of battery electrodes for electric cars, which has increased its demand and price  considerably, reaching today a value of US$ 33,000 per tonne, after a historic peak  in 2018, at around US$ 90,000 per tonne.

Cobalt is mainly extracted from copper and nickel mines, with the Democratic Republic of the Congo being the main producer. But the political instability of that country, coupled with the growing demand (as shown in Fig. 2) has led to the search for this metal in other countries, presenting itself as a great opportunity for other copper-producing countries, such as Chile, Peru, Australia and Canada.

At Aminpro we are currently conducting various flotation tests of copper-cobalt minerals from pyrite-rich Scavenger tailings, both at laboratory- and pilot-scale. After experimenting with several operating conditions, we will move on to a stage of operating optimization, which will then be complemented by simulations of different flotation circuits, to finally validate them in the pilot plant.

Desafio 10xAminpro

Aminpro has joined the 10xChallenge

by General NewsOur company

Chile is undergoing a period of intense and historical social unrest, mainly motivated by large economic inequality.

It is in this context that Aminpro has decided to join the 10xChallenge, agreeing to reduce the gap between its maximum and minimum salary to just 10 times.

https://www.youtube.com/watch?v=Ra8kA_chgpo

We have done a collective effort and we have agreed on a long term commitment. By joining the 10xChallenge we seek to promote the sustainable development of our company, for our workers and stakeholders.  We invite our collaborators, clients, and partners to join this initiative.

Alex Carvajal
General Manager

This agreement will position Aminpro as an innovative company that is deeply involved with the society, constantly seeking to improve the quality of life of its workers and partners.

Aminpro has a new Technical and Sales Manager

by General NewsOur companySin categoría

Aminpro gives a warm welcome to our new Technical and Sales Manager: Max Valenzuela. Max is a metallurgical engineer from Universidad de Santiago de Chile, with more than 30 years of experience. In that time he has become an expert engineer in comminution and mineral concentration processes.

During his career he has fuflfiled many roles in the mining and metallurgical business, in companies such as: Centro de Investigación Minera Metalgúrgica (CIMM), Yáñez y Valenzuela Ingeniería, Centro de Investigación e Innovación en Minería y Metalurgia (IM2), among others.

We are confident that bringing Max Valenzuela into our team will strengthen the position of  Aminpro in the southamerican market.

Aminpro presented at Procemin Geomet 2019

by Fairs and exhibitionsInnovationOur company

Aminpro is well known for being an innovative company, where research and development of new metallurgical methodologies, equipment, tests and protocols are of great importance.

Given that, 2 of our engineers presented research works at Procemin Geomet 2019, which took place at the Sheraton Hotel in Chile last week. In that international conference, we presented two works related to milling and flotation process.

procemin 1

Aminpro’s participation began on the Thursday 21st of Novembre, with the presentation of Patricio Berrio, Chief of Engineering, titled “The MiniBond test: description, calibration and sources of error”.

The MiniBond offers a more accessible alternative for the generation of geometallurgical data, allowing to include the Bond Work Index in the block models at a lower cost and in less time than the standard Bond test

.On Friday, our Senior Engineer David Barriga presented the work titled “Pilot-scale of Cu-Mo separation as a tool for industrial plant design”, showing the benefits of carrying out pilot-scale tests to compare with the simulation data, in order to generate a better industrial plant design

Pilot-scale tests allow to reduce the risk and uncertainty related to the construction and operation of new industrial plants
