Research Progress on Ammonium Molybdate
2024-11-25
Our country has abundant molybdenum resources, which is one of the six major advantageous mineral resources in China. It is also a major producer and trader of aluminum resources, holding an important position internationally. Therefore, it is crucial to pay high attention to the safety of our molybdenum resources and to develop and utilize molybdenum production rationally. About 30% of production manufacturers still use traditional processes, mostly small factories, while approximately 50% use improved traditional processes, and around 20% adopt oxygen pressure cooking and alkaline pressure cooking methods. In contrast, foreign countries generally use advanced processes such as pressure alkaline leaching, extraction, or ion exchange. Most of the ammonia and acid gases generated during the production process are not recovered and utilized, leading to environmental pollution, while foreign countries typically recover and treat ammonia and acid gases for reuse.

Comparative Study of Crystallization Process and Ammonium Molybdate Quality
2024-11-25
Crystallization is a process of mutual transformation between substances, often accompanied by phase changes. It is a complex chemical reaction process, such as the precipitation of solute crystals in the liquid phase due to changes in external conditions, and the chemical reactions of various components in the gas phase generating crystals. Crystallization is an ancient and traditional topic in the field of chemical research.
