Jinchuan refinery domestic extraction agent industrial test achieved a major breakthrough

     Refinery production line pressure extraction processes used in the extraction agent has been using imported products, some impact on production costs and production organization. For this reason, nickel and cobalt refinery and the School of Metallurgical Engineering and technical personnel in close cooperation, actively seek the same type of domestic instead of imported extraction agent extraction agent approach. In more than a year's time, we have organized a series of experimental studies. In a small trial on the basis of the progress made, in April this year launched a domestic extraction agent semi-industrial tests and industrial test by test to prove that domestic extraction agent under certain conditions, to meet the requirements of impurity achieved domestically instead of imported extraction agent extractant scientific basis. After successfully applied to domestic extraction solvent extraction process, annual savings of more than 100 million.
