The production technology includes the following process: Mixing the spent catalysts with supplementary raw material, after roasting, leaching, precipitation, filtration and flaking process, getting final product of vanadium pentoxide and crude ammonium molybdate.

According to the characteristics of spent catalysts and market needs of vanadium pentoxide and crude ammonium molybdate, the company has designed scientific extraction method, which effectively combines the process of mixing, roasting, precipitation and flaking together with strict operation of the workers. This method can also adjust to different raw material and different environmental conditions with separate parameters such as temperature, revolving speed, density, etc., which has helped make whole process more precise, stable and reliable and the product of superior quality.

According to the requirement of the ISO 9001:2000 quality management system, the company places a strong emphasis to take stringent quality control measures throughout the whole production process. The company always tries its best to fulfill the request to quality from the customers and gets steady operation and improvement to the quality all the time, which ensures a continuous development to the whole company.
