Sunresin has developed some resins and extraction process for high selectivity of main metals and valuable metals. However, in this process, it is generally necessary to add some impurity removal steps, and many impurities are associated with the target, and the content is high. In order to reduce the processing cost, pre-treatment of impurities can be carried out through some resins in advance to reduce the burden of extraction of the main equipment.

On the other hand, Many industries require high purity metals, and trace amounts of impurities are not allowed, such as 4N Ga. At this time, the finishing equipment can be added to remove some trace impurities after the main equipment. Mostly, the combination process is need to achieve high purity requirements.
