Looking for books or information on cadmium metallurgy
Thread Content
Dear heroes, can you recommend some books or information on cadmium metallurgy? It would be best if you can provide a download link or send it to my email. If it is inconvenient, you can also provide the name of the book or information! my email: wncutlhy@qq.com (Extra large attachments can be added) Thank you for your help! ! ! :lol :lol :lol
Take a look at the heavy non-ferrous metal smelting design manual lead zinc bismuth volume
I want to do vacuum distillation. If anyone has a furnace for this, please contact me. Just make 1# cadmium. I only have experience doing rough cadmium.
There is little information on raw materials and processes such as Huludao Zinc Plant, Zhuye Smelter, Yunnan Jianchuan, etc.

There are no books or information on cadmium metallurgy in bookstores. Only our factory has these processes.
There is a semi-continuous vacuum furnace for refining cadmium, using 98% crude cadmium as raw material, with a daily output of 3-4 tons of 4N refined cadmium, and an investment of less than 20,000 yuan.
-- Twenty thousand or two million or twenty million? I don't have the nerve to mention 200 million, for fear of dampening enthusiasm. Now, to open a tofu shop with a daily output of 3 to 4 tons, the investment is more than 20,000, right? ;P --
That's true! The investment to open a tofu shop with a daily output of 3-4 tons is more than 2W.~
On the 8th and 9th floors, I said that the 20,000 investment does not include factory buildings, but only equipment investment. This kind of equipment can only use more than 98% of crude cadmium. The production cost is not very high. Cadmium recycling is very good, but crude cadmium is not easy to buy.
There are currently no newer monographs or literature on cadmium metallurgy, but its process flow is relatively representative and includes a complete smelting process, so it is a grass-roots exercise and practice* A good place to go. There are many sources of raw materials. If high-cadmium zinc or cadmium ash is used as the raw material, the fire process is usually used. ； For cadmium-containing smoke, a combined wet and fire process is often used. There is also a fully wet process suitable for processing copper cadmium slag from zinc smelting enterprises. However, due to its complicated process flow and high energy consumption, it has gradually not been used. At present, Zhuzhou Smelting Co., Ltd. adopts a combined wet and fire method to process copper cadmium slag. The process includes leaching, neutralization, replacement, natural oxidation, leaching, neutralization and hydrolysis, replacement copper removal, briquetting, alkali smelting, vacuum distillation, and casting.
