Ruthenium is a rare type of ruthenium with high density, high melting point, high conductivity and high corrosion resistance, and is widely used in electronics, chemical industry, medical treatment, aviation and other fields. The market for ruthenium is also very high, currently around 300 yuan per gram. However, the reserves of ruthenium are very limited, and they are mainly distributed in a few countries such as South Africa and Russia, so the ** ruthenium is facing huge challenges and risks.
So, is ruthenium-containing waste a viable solution? This article will analyze the following two aspects:
First of all, the value of ruthenium-containing scrap is obvious. According to statistics, about 1,000 tons of ruthenium-containing waste are generated globally every year, most of which comes from the waste and renewal of electronic products, such as mobile phones, computers, hard disks, etc. If these wastes can be effectively improved, the utilization rate of ruthenium can be improved, the mining of raw ore can be reduced, resources can be saved, the environment can be protected, and at the same time, economic benefits can be created, income can be increased, and development can be promoted.
Secondly, the possibility of ruthenium-containing waste exists, but it also faces some difficulties and challenges. At present, there are two main methods for ruthenium-containing waste, one is the chemical method, that is, the use of chemical reagents such as acid and alkali to dissolve ruthenium from the waste, and then purify it through precipitation, electrolysis and other steps; The other is the physical method, that is, the use of magnetic separation, gravity separation and other physical means to separate ruthenium from the waste, and then through smelting, refining and other steps to purify. These two methods have their own advantages and disadvantages, such as the advantages of the chemical method is high rate, and the disadvantage is high cost and high pollution; The advantages of the physical method are low cost and low pollution, and the disadvantage is that the first rate is low. Therefore, how to choose the right method, and how to improve the efficiency and quality, is the key issue of ruthenium-containing waste.
