Embodiment 1

[0042] A method for preferentially absorbing ruthenium in a process for enriching platinum group metals and gold, comprising the following steps:

[0043] (1) Take the cooked coke gem raw material, pulverize it into a coke coke powder with a fineness of 200 mesh for subsequent use; mix and stir concentrated sulfuric acid and water with a mass fraction of 98% at a mass ratio of 0.9:1 to obtain a sulfuric acid solution, and take the molar Concentration is the hydrochloric acid solution of 1mol / L standby;

[0044] (2) Add sodium chloride, sulfuric acid solution and hydrochloric acid solution to the cooked coke gemstone powder, mix evenly by the mass ratio of 4.5:1:4.5:50, obtain mixed material;

[0045] (3) The mixed material obtained above was transferred to a reaction kettle, and reacted at 90° C. for 1 h under 10 kw / h visible light irradiation. A condensing device is used to control the temperature of the gas above the reactor to ≤50°C, and the gas generated during the reacti...

Abstract

The invention provides a method for preferentially absorbing ruthenium through a technology enriching platinum group metal and gold. The method comprises the following steps: (1) crushing raw materials containing platinum group metal and gold into powder; (2) adding alkali metal chloride, a sulfuric acid solution and a hydrochloric acid solution to the powder, and performing uniform mixing, so asto obtain mixed materials; (3) heating the mixed materials, absorbing tail gas with the hydrochloric acid solution in a reaction course, and after reaction is completed, and performing filtering to remove filter residues, so that the solution is obtained, and the obtained solution is an enriched solution of the platinum group metal and the gold. Through the adoption of the method disclosed by theinvention, the hydrochloric acid solution is used for absorbing ruthenium oxide gas generated in the reaction course, so that risk in the extracting course of the platinum group metal is reduced, andthe recovery rate of rare metal ruthenium is also increased.

Description

technical field [0001] The invention relates to the technical field of noble metal chemical metallurgy, in particular to a method for preferentially absorbing ruthenium in the process of enriching platinum group metals and gold. Background technique [0002] Platinum group metals have become a class of metals because of their incomparable and excellent comprehensive physical and chemical properties, bright and bright colors that remain unchanged all year round, long-lasting and stable service life and long-term storage without depreciation, and unique biological and catalytic activities. Special metals that are irreplaceable and widely used in various fields of human life. [0003] However, platinum group metals are precious metals, and are the metals with the least amount of resources among all the metals stored in the earth's crust. Its distribution is very uneven, and China's platinum group metal resources are poor, accounting for only 0.2% of the world's total reserves....
