Ruthenium is a rare platinum group metal with excellent characteristics such as high density, hardness, electrical conductivity and chemical stability, and has a wide range of applications in catalysts, electronic equipment, alloy manufacturing and other fields. However, ruthenium is a very limited natural resource and is mainly extracted from platinum ore, which requires a lot of energy and cost to mine and process. Therefore, the utilization of ruthenium powder is of great significance for saving resources, protecting the environment, reducing costs and improving benefits.
First of all, let's take a look at the ruthenium powder According to the market, the ruthenium powder mainly depends on its purity and market supply and demand, and the amount of crude ruthenium that can be refined from one kilogram of ruthenium powder depends on the percentage of ruthenium in the ruthenium powder and the refining process. As a rare metal, ruthenium powder is of great significance in resource reuse and environmental protection. Its *** varies greatly depending on the purity. For example, a 90% purity ruthenium powder may reach 70 yuan per gram, so one kilogram is 70,000 yuan; The 99% purity ruthenium powder can reach 300 yuan per gram***, and one kilogram is 300,000 yuan.
Secondly, let's take a look at the ** process of ruthenium powder. The process of ruthenium powder is generally divided into the following steps:
Collection and sorting of ruthenium powder. There are two main types of ruthenium powder, one is a by-product in the industrial production process, such as ruthenium powder produced by electroplating, electrolysis, catalysis, etc.; The other is waste ruthenium products, such as ruthenium alloys, ruthenium electrodes, ruthenium catalysts, etc. These ruthenium powders need to be collected and sorted according to different **, form, purity, etc., so as to facilitate subsequent processing and refining.
Pretreatment and analysis of ruthenium powder. The pretreatment of ruthenium powder is mainly to remove impurities and improve purity, and the commonly used methods include magnetic separation, screening, washing, flotation, pickling, etc. The analysis of ruthenium powder is mainly to determine the content of ruthenium and the composition of other elements in ruthenium powder, and the commonly used methods include spectroscopic analysis, chemical analysis, fire analysis, etc.
Reduction and purification of ruthenium powder. The reduction and purification of ruthenium powder is the process of reducing the ruthenium in ruthenium powder to metal ruthenium and further improving its purity. The wet process uses a chemical reaction to reduce the ruthenium in the ruthenium powder to water-soluble ruthenium salt, and then through precipitation, filtration, drying and other steps to obtain metal ruthenium powder. The dry process is to use a high-temperature reduction furnace to reduce the ruthenium in the ruthenium powder to metal ruthenium, and then obtain the metal ruthenium ingots through electrolysis and other steps.
Finally, let's talk about the best interests of ruthenium powder. The best interests of ruthenium powder are mainly reflected in the following aspects:
Resource interests. The utilization of ruthenium powder can effectively save the natural resources of ruthenium, prolong the service life of ruthenium, reduce the mining and processing of ruthenium ore, and protect the scarcity and value of ruthenium.
Environmental benefits. The utilization of ruthenium powder can effectively reduce the waste and pollution of ruthenium powder, avoid the harm caused by ruthenium powder to the environment and human health, improve the recycling rate of ruthenium powder, and realize the green development of ruthenium powder.
Financial benefits. The utilization of ruthenium powder can effectively reduce the production cost of ruthenium, improve the utilization efficiency of ruthenium, increase the added value of ruthenium, and create economic benefits of ruthenium.
To sum up, the first and best processes of ruthenium powder are determined according to the characteristics of ruthenium powder and market conditions, and the best interests of ruthenium powder are multifaceted, which have a positive effect on resources, environment and economy. Therefore, the utilization of ruthenium powder is a meaningful cause that deserves our joint efforts and support.
