Did you know that Aminpro conducts Cobalt metallurgical tests?

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

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
