Molybdenum (atomic symbol: Mo, atomic number: 42) is a Block D, Group 6, Period 5 element with an atomic weight of 95.96. The number of electrons in each of molybdenum's shells is [2, 8, 18, 13, 1] and its electron configuration is [Kr] 4d 5 5s 1. The molybdenum atom has a radius of 139 pm and a Van der Waals radius of 209 pm.

98 of the industrial mineral containing molybdenum is molybdenite. flotation method is often used to extract molybdenum concentrate. in processing molybdenum ore, to focus on preventing over grinding, and in the production process, multistage grinding and multistage separation process are generally adopted, to gradually achieve molybdenum monomer.

This molybdenum flotation circuit, based on 250-500 tons per 24 hours is designed for low-grade molybdenum ore having high-grade streaks and with pyrite-quartz gangue.It is also basically sound for many other friable sulphide ores, such as antimony, silver and even some lead ores. The basic ideas stressed in this moly flotation flowsheet are the importance of simplicity …
