The desorption column is used in the carbon slurry gold extraction process, and the gold-loaded carbon is charged into the desorption column, and interacts with the passing medium sodium hydroxide solution to separate the gold from the gold-loaded carbon to form a noble liquid.
The domestic desorption column is designed by China Nonferrous Metals Institute and is mainly produced by internal machines, various mines and milk machines. There are currently three kinds of specifications. The technical performances are listed in Table 1. The external dimensions are shown in Figure 1, Table 2 and Figure 2.
The technical parameters of the desorption column produced by Xinhai Mining Machine are shown in Table 3, and the appearance is shown in Figure 3.
