Description

Technical Field

[0001] The utility model relates to the technical field of molybdenum oxide production, in particular to a high-purity soluble molybdenum oxide crystallizer. Background Art

[0002] Molybdenum oxide is a commonly used substance in the chemical industry. It has excellent lubricating properties and can also be used to manufacture high-performance catalysts and semiconductors. The current method for producing molybdenum oxide is generally the pyrometallurgical method, which involves oxidizing and roasting molybdenum concentrate at 600°C to 700°C to obtain molybdenum roasted sand. The molybdenum roasted sand is then leached with ammonia and impurities removed to obtain a solution containing ammonium molybdate. Nitric acid is then added to the ammonium molybdate solution to react with the nitric acid and ammonium molybdate to generate solid molybdenum oxide crystals. The molybdenum oxide precipitates in the solution and is then subjected to solid-liquid separation to obtain high-purity molybdenum oxide. The crystallized object is then washed with water and dried. The current drying method usually relies on electric heating lamps to heat and dry the molybdenum oxide. However, the electric heating lamps can only irradiate a portion of the molybdenum oxide crystals, making it difficult to heat the molybdenum oxide evenly and resulting in poor drying effect.
