The main results are as follows: (1) improving the recovery rate of Molybdenum separation and the quality of Molybdenum concentrate products in an all-round way is a very valuable strategic resource, saving resources and comprehensive utilization is particularly important, as far as the recovery rate of Molybdenum ore dressing is concerned, At present, the recovery rate of Molybdenum in China is 1% lower than that in foreign countries. For the quality of Molybdenum concentrate products in China, the content of Molybdenum in about 40% Mo concentrate in China is less than 50%, some are only 42%, and some are only 28%. It is suggested that all large and medium-sized Molybdenum mining enterprises. To set up a special experimental research and technical transformation research group to speed up the pace of technological innovation, starting with improving the concentrate grade and recovery rate in the coarse separation section, the grinding and separation process structure, classification, mineral processing equipment efficiency and comprehensive drug use system in the cleaning section are studied. (2) rationally develop resources and take the road of sustainable development. China is rich in the total amount of Molybdenum resources, but the per capita possession is less than half of the worldundefineds per capita share, and the grade is low, and there are many single Molybdenum deposits. The output of by-product Molybdenum accounts for only about 3% of the total output of Molybdenum. Therefore, there is an objective weakness in the international competition of Molybdenum primary products produced in China. In order to make rational use of resources and take the road of sustainable development, it is suggested that: first, strengthen the overall planning of Molybdenum ore resources mining and separation, moderately control the total amount of development, put an end to random mining and overdigging, close the separation plants with low mineral processing index, environmental protection and big safety problems; The third is to curb the construction of extensive small-scale mining and separation mines. (3) with the development of society and the progress of science and technology, mineral processing equipment is also innovating and developing. Since the late 1980s, in order to improve the economic index of Molybdenum mineral processing, Canada, the United States and other developed mining countries have studied the technological process of mineral processing and the progress of mineral processing equipment. Now the mineral processing equipment has achieved large-scale and automation, and will be further intelligent in the future. Now, some large gold, copper and iron ore concentrators have realized intelligence on the basis of automation, such as expert system control of grinding circuit, which is an intelligent reasoning system based on knowledge. Have the knowledge and experience of experts in a special field, and can use knowledge like experts to make intelligent decisions through reasoning. With the development of automatic control technology, computer technology and instrument technology, the automatic control of mineral processing process will be developed from the simple DDC control in the past to the comprehensive automatic intelligent control of the whole concentrator. (2) the mining history of the combined process of separation and metallurgy is nearly a hundred years. The grade of the selected Molybdenum ore and the copper Molybdenum ore is gradually decreasing, and the composition of the mining ore is becoming more and more complex, so it is more and more possible to study the combined process of separation and metallurgy. In particular, hydrometallurgy, with the help of membrane technology and resin technology to regenerate leaching agents, recycling leachate is also on the schedule.
