benchmark column separation plant - Opis:
- The granulation method of λ-MnO2 adsorbent employing chitin-based binder, which has efficient selectivity towards lithium ion, has been developed. The granules of ca. 1 – 2 mm with high resistance to the column operation for seawater (pH = 8.1) can be achieved. The laboratory scale column separation with the granulated adsorbent shows that lithium ions from seawater can be selectively recovered against the majority of co-existing cations. In addition, the elution of Mn from the adsorbent can be prevented. The benchmark column separation plant with seawater intake 200 L/h has been built and the whole process was verified and evaluated. The composition analysis of dried precipitated salts showed ca. 35 % efficiency of lithium recovery in the benchmark plant. In order to enhance the lithium recovery efficiency the following recovery steps are expected when routine techniques are applied.
