Jinchuan Refinery made a major breakthrough in the industrialization of domestic extractants

2020-04-27

The extractant used in the extraction process of the pressurized production line of the refinery has always used imported products, which has a certain impact on the production cost and production organization. To this end, the refinery works closely with the engineering and technical personnel of the Chemical and Metallurgical Institute of the Nickel Cobalt Institute, and actively seeks to replace the imported extractant with the same type of domestic extractant. In more than a year, he has organized a series of experimental research work. On the basis of the progress of small-scale experiments, semi-industrial tests and industrialization tests of domestic extractants were carried out in April this year. The tests proved that domestic extractants could meet the requirements for removing impurities under certain conditions, and made domestic extractants replace imported Scientific basis of extractant. After the domestic extractant is successfully used in the extraction process, it can save more than 1 million yuan per year.
