Ruthenium slag refers to waste containing ruthenium, which is usually used in petrochemical, medical, electronics and other industries. Ruthenium is a rare material with high economic value and industrial use, so the utilization of ruthenium slag is of great significance. So, what are the general processes of ruthenium slag**?
First of all, the collection of ruthenium slag. The collection of ruthenium slag is the first and most critical step in the utilization of ruthenium slag. The collection of ruthenium slag requires professional equipment and personnel to ensure the quality and safety of ruthenium slag. The collection of ruthenium slag can be divided into two ways, one is on-site collection, that is, the collection is carried out at the place where the ruthenium slag is generated, which can reduce the loss and pollution of ruthenium slag, but requires cooperation and coordination with the ruthenium slag producer; The other is transit collection, that is, the ruthenium slag is transported from the place of generation to the designated station for collection, which can expand the scope of ruthenium slag, but it is necessary to pay attention to the safety and specifications of the packaging and transportation of ruthenium slag.
Secondly, the pretreatment of ruthenium slag. The pretreatment of ruthenium slag refers to the sorting, cleaning, drying, crushing and other operations of ruthenium slag to improve the purity and uniformity of ruthenium slag and prepare it for subsequent extraction and separation. The pretreatment of ruthenium slag requires professional equipment and technology to ensure the quality and efficiency of ruthenium slag. The pretreatment of ruthenium slag can be divided into two ways, one is physical pretreatment, that is, the physical characteristics of ruthenium slag, such as density, magnetism, conductivity, etc., are used to carry out screening, magnetic separation, electric separation and other operations, which can simply and quickly remove impurities and foreign matter in ruthenium slag, but it is difficult to separate other metal elements in ruthenium slag; The other is chemical pretreatment, that is, the chemical characteristics of ruthenium slag, such as solubility, redox, etc., are used to carry out pickling, alkali washing, oxidation, reduction and other operations, which can effectively separate other metal elements in ruthenium slag, but requires a large amount of chemical reagents and energy.
Finally, the extraction and separation of ruthenium slag. The extraction and separation of ruthenium slag refers to the separation of the ruthenium element in the ruthenium slag from other elements to obtain a high-purity ruthenium product. The extraction and separation of ruthenium slag requires professional equipment and technology to ensure the best rate and quality of ruthenium. The extraction and separation of ruthenium slag can be divided into two ways, one is wet extraction and separation, that is, the chemical properties of ruthenium solution are used to dissolve, extract, precipitate, electrolyze and other operations, which can accurately control the concentration and purity of ruthenium, but need to treat a large amount of waste liquid and waste gas; The other is dry extraction and separation, that is, using the solid-state chemical properties of ruthenium to carry out smelting, refining, crystallization and other operations, which can directly obtain solid ruthenium products, but requires high temperature and high pressure conditions and equipment.
The above is the general process of ruthenium slag, and different enterprises may adopt different methods and technologies to adapt to different ruthenium slag and needs. Ruthenium slag is generally between 1,000 yuan and 2,000 yuan per kilogram, depending on the quality of ruthenium slag and market supply and demand. Ruthenium slag is a cause that is conducive to environmental protection and resource conservation, and is also a cause that is conducive to economic development and social progress, which deserves our support and participation.
