The first phase of the project adopted the combined “ flotation enrichment + pyrometallurgy” process , with an expected annual production of 50,000 tonnes of copper.  The second phase of the project, for its part, concerned the recycling of the company's copper and cobalt in March 2018.  Trial production took place on December 26, 2018.  The first batch of copper cathode was produced on April 15, 2019, and the production reached the standard in September 2019.  The total investment in Phase II is approximately $210 million, with planned annual production of 40,000 tonnes of copper and 1,500 tonnes of cobalt.
