[0036] Example 1
[0037] The method of extracting osmium, iridium, and ruthenium from iridium osmium ore and directly processing them into corresponding compounds involves the following steps:
[0038] 1) After the aluminum is heated to melt, add the materials according to the mass ratio of material: aluminum = 1:2, and mix them evenly. After the mixture is heated to 1200°C, the temperature is kept for 40 minutes to obtain a molten alloy;
[0039] 2) Put the molten alloy of step 1) into water at room temperature for water quenching, so that the molten alloy becomes alloy particles;
[0040] 3) Add the alloy particles of step 2) to the lye with a mass concentration of 7%, and react for 2h at 90℃ to completely dissolve the aluminum in the alloy particles in the lye. After solid-liquid separation, the content Aluminum lye and alloy; aluminum-containing lye is sent to post-processing to recover aluminum;
[0041] 4) According to the mass ratio of alloy: sodium peroxide: sodium hydroxide =...

[0049] Example 2
[0050] The method of extracting osmium, iridium, and ruthenium from osmium-iridium platinum ore and directly processing them into corresponding compounds involves the following steps:
[0051] 1) After the aluminum is heated to melt, add the materials according to the mass ratio of material: aluminum = 1:3, and mix them evenly. After the mixture is heated to 1500°C, the temperature is kept for 20 minutes to obtain a molten alloy;
[0052] 2) Put the molten alloy of step 1) into water at room temperature for water quenching, so that the molten alloy becomes alloy particles;
[0053] 3) Add the alloy particles of step 2) to the lye with a mass concentration of 25%, and react for 2h at 25°C to completely dissolve the aluminum in the alloy particles in the lye. After solid-liquid separation, the content Aluminum lye and alloy; aluminum-containing lye is sent to post-processing to recover aluminum and alkali;
[0054] 4) According to the mass ratio of alloy: sodium peroxi...

[0062] Example 3
[0063] The method of extracting osmium, iridium, and ruthenium from the aqua regia insoluble matter containing ruthenium, iridium, and osmium and directly processing them into corresponding compounds, through the following steps:
[0064] 1) After the aluminum is heated to melt, add the materials according to the mass ratio of material: aluminum = 1:2, and mix them evenly. After the mixture is heated to 1300°C, the temperature is kept for 30 minutes to obtain a molten alloy;
[0065] 2) Put the molten alloy of step 1) into water at room temperature for water quenching, so that the molten alloy becomes alloy particles;
[0066] 3) Add the alloy particles of step 2) to the lye with a mass concentration of 15%, and react for 2h at 60℃ to make the aluminum in the alloy particles completely dissolve in the lye. After solid-liquid separation, the content Aluminum lye and alloy; aluminum-containing lye is sent for post-processing to recover aluminum;
