Description

eleven

The invention relates to the field of metallurgy of rare metals, ei specifically to methods for processing metal-phosphorus-containing solutions.

The purpose of the invention is to increase the degree of separation of metal and phosphorus.

The method is illustrated as follows.

Example 1. Anion exchanger with a molybdenum ion content of 51 mg / l (for molybdenum) and phosphorus ions of 4.1 mg / l (for phosphorus) is desorbed under static conditions with a ratio of volumes of ion exchanger: solution equal to 1: 1, under a mixer, time contact at the stage of 1 hour. After the contact time (1 hour) has expired, the ion exchanger and the solution are separated. The solution is extracted and the ion exchanger is filled with a fresh volume of solution. Each volume of ion exchanger is eight

mov solution. The final ion exchanger is analyzed for the content of molybdenum and phosphorus, the results of the experiment are shown in Table. one.

5 Example 2. The initial anion exchanger AL (p), saturated from wash water, contains 28 mg / g Sc and 23 mg / g phosphorus ions. Under the conditions of Example 1, phosphorus ions are desorbed with solutions of sulfuric acid and sodium chloride solution (prototype).

The results of the experiment are given in table. 2

Thus, as follows from the tables, in this method, the separation factor of molybdenum from phosphorus is 2.8-3.4 times higher than in the prototype, and the separation factor of scandium from phosphorus is 3-4.2 times the ratio.
