Molybdenum Flotation Circuit and Flotation Cells

Oct 01, 2012· There are several flow sheets (listed in Fig. 1a and b) used in the flotation recovery of copper and molybdenum from their porphyry sulfide ores. Fig. 1a is a typical flow sheet that consists of two stages (Raghavan and Hsu, 1984, Bulatovic, 2007, Liu et al., 2011).The first stage, commonly known as the copper circuit, produces a bulk copper sulfide–molybdenum sulfide concentrate.

This paper introduces the most commonly used molybdenum flotation flowsheet, together with the introduction of the flotation chemistry. Many different types of flotation cells are used in modern moly plants, and each type of flotation cell has its own unique advantages suited for particular ore and process conditions.

An investigation of the factors affecting the recovery of ...

Our range of flotation solutions include frother and collector programs for coal, copper, molybdenum, phosphate, potash, and more. All of our solutions address your process holistically, helping you optimize your flotation circuit to achieve greater selectivity, recovery, grade, and ultimately, cost performance.

World's largest flotation cells improve copper and ...

May 25, 2018· Therefore, the foam plays an indispensable role in all flotation mechanisms. Jinduicheng Molybdenum Co., Ltd., located in Shanxi Province, is currently holding a largest molybdenum mine in china. This company is using flotation technique for ore processing where diesel is used as a collector, and fusel is used as a frother.

Flotation separation of molybdenite from chalcopyrite ...

Mar 10, 2016· Particle size is a very important factor affecting flotation properties of molybdenite. In porphyry copper–molybdenite ores the flotation conditions (grinding, reagents, bubble size, etc.) all are optimized with respect to Cu and not Mo. Fig. 2 shows that the optimum flotation particle size for molybdenite is around 20 μm, and the size fraction 6.8 μm exhibits the lowest recovery and ...

Enrichment of Molybdenum and Fluorite by Flotation of ...

Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash.

Molybdenum Flotation Circuit and Flotation Cells

Typically, rougher molybdenite flotation and recovery from bulk copper/molybdenum concentrates involves the use of alkalisulfides, Nokes reagents, cyanides, oxidants, and/or thermal treatment to depress copper sulfide minerals. The bulk copper/molybdenum feed generally varies from 0.2% Mo to 1.0% Mo, and with traditional reagents the single-stage rougher flotation recovery of molybdenite ...
