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.

If you are looking for more information about our leaching work, please do not hesitate to contact us.

Virtual Access to Aminpro – Innovation during the Pandemic

by Innovation

At Aminpro we have always aimed to be an innovative company, with an open doors policy, looking to fulfil all the technical requirements of our clients, while meeting the most strict safety and quality standards.

We used to make ourselves proud to be always willing to open our doors to receive our clients, so they could oversee the development of their tests in-situ, and even offer them a physical workspace in our facilities for the whole duration of their project. However, the current pandemic forced us to stop this practice to maintain social distance and take care of the health of our clients, partners and workers.

That’s why we are proud to inaugurate a new and innovative service of Virtual Access to Aminpro! We have installed cameras with live streams that allow our clients to oversee their tests in real-time remotely, keeping instantaneous communication.

We have 6 high-resolution cameras (4K) with a 360 degrees field of view, which oversee the pilot plant and the metallurgical laboratory.

In Aminpro we are constantly checking our procedures and practices to incorporate innovative solutions that are useful for our clients. If you need more information about our services, please contact us.

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.

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.

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
