Platinum Salt Recovery Technology and Its Application Prospects

Platinum is a rare and precious metal with excellent physical and chemical properties, widely used in industries, pharmaceuticals, electronics, catalysts, and other fields. However, platinum ore resources are limited, mining costs are high, and a certain amount of platinum salt waste is generated during its production and processing. With the increasing global awareness of resource and environmental protection, platinum salt recovery has become an important technical field, with the aim of improving the recovery rate of platinum metal, achieving resource recycling, and reducing environmental pollution.

Platinum salt recovery method:

The main methods for platinum salt recovery include fire method, wet method, and biological method. The following is a brief introduction to these three methods: 1. Fire method: Fire method is a traditional platinum salt recovery method that mainly separates platinum metals from other substances in waste through high-temperature smelting, gasification, smelting and other processes. The fire method has a high recovery rate, but due to its high energy consumption, complex operation, and the production of a large amount of harmful gases, it has gradually been replaced by other recovery methods. 2. Wet process: Wet process recovery is a chemical leaching method that uses chemical reagents such as acid and alkali to dissolve platinum metals from waste, and then obtains pure platinum metals through precipitation, filtration, reduction, and other steps. Wet method operation is simple and low in energy consumption, but it has high requirements for the composition of waste, limited by the type and concentration of waste. 3. Biological method: Biological method is a new type of platinum salt recovery method that utilizes the adsorption, precipitation, and reduction capabilities of microorganisms to recover platinum metals from waste. Biological methods have the advantages of environmental protection, low energy consumption, and low cost, but their application range and recovery effect are influenced by factors such as microbial species and growth conditions.

Progress in Platinum Salt Recovery Technology

1. Improve recovery rate: Continuously improve the efficiency and recovery rate of platinum salt recovery by optimizing process parameters, improving equipment, introducing new reagents, and other methods. For example, using technologies such as secondary leaching and combination reagents can significantly improve the effectiveness of wet recovery. 2. Reduce environmental pollution: During the recycling process, gradually reduce the generation and discharge of harmful substances, and reduce their impact on the environment. For example, using biological methods instead of fire and wet methods can reduce the discharge of harmful gases and wastewater. 3. Innovative biological method technology: By screening efficient microbial strains, optimizing cultivation conditions, and improving operational methods, continuously improving the applicability and effectiveness of biological method recovery. For example, using gene editing technology to selectively modify microbial strains and enhance their adsorption capacity for platinum metals.

Industry Application and Development Prospects

Platinum salt recovery technology has been widely applied in various industries, such as automotive exhaust catalysts, chemical catalysts, fuel cells, electronic products, and so on. With the continuous improvement and promotion of recycling technology, the recovery rate of platinum metal will gradually increase, and it is expected to reduce dependence on platinum mineral resources. In the future, with the global emphasis on environmental protection and resource utilization, platinum salt recovery technology will usher in a broader market. The cooperation and support between the government and enterprises, as well as the continuous innovation of research institutions, will drive the continuous development of platinum salt recovery technology. In addition, with the rapid development of biotechnology, biological platinum salt recovery technology is expected to become the mainstream, providing important support for achieving resource recycling and environmental protection goals.

Platinum salt recovery is an important technical field that combines environmental protection, economy, and technology. With global attention to resource and environmental protection, the research and application of platinum salt recovery technology will be increasingly valued. By continuously optimizing process methods, reducing environmental pollution, and improving recycling efficiency, platinum salt recycling will make important contributions to achieving resource recycling and environmental protection goals.
