The low and highly variable flotation recovery of molybdenum may be a result of several factors, all related to the properties of the molybdenite (MoS 2) mineral.Molybdenite crystal structure consists of hexagonal layers of molybdenum atoms between two layers of sulphur atoms (Fig. 2).Strong covalent bonds act within S–Mo–S …
The depressive efficiency of sodium silicate, sodium hexametaphosphate, and tartaric acid on the flotation separation of molybdenum oxide from fluorapatite were examined using cetylpyridinium chloride (CPC) as the collector. The corresponding depression mechanisms of all three depressants were studied with the use of laboratory …
Nalco Water offers a diverse portfolio of flotation programs, all of which are developed to overcome flotation process challenges encountered in a variety of metals and mineral operations. Our range of flotation solutions include frother and collector programs for coal, copper, molybdenum, phosphate, potash, and more.
The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to …
Molybdenum is a rare metal with a high melting point, high strength, and high elastic coefficient. As a strategic mineral resource, molybdenum is widely used in the fields of iron and steel, petroleum, chemical industry, electrical and electronic technology, medicine, and agriculture [1,2,3].Molybdenum deposits in China are mainly porphyry …
Molybdenum minerals are often associated with copper sulfide minerals . ... Meanwhile, the recovery of chalcopyrite and molybdenite in the flotation of mixed minerals system was calculated based on the assumption that copper and molybdenum belong to chalcopyrite and molybdenite, respectively. The froth and tailing fractions were analyzed …
As the major mineral reserve for molybdenum, molybdenite (MoS 2) is commonly found in porphyry copper deposits. Molybdenite is naturally floatable and can be separated from copper sulfide mineral using froth flotation.
The molybdenum production process is: Crushing - Grinding - Molybdenum flotation - Roasting. In the extraction of molybdenum, we adopt segmented grinding and multi-stage separation process. As it can gradually achieve monomer dissociation and ensure a high recovery rate of molybdenum concentrate. No excessive grinding.
Molybdenum is an important alloy element for metallurgical industry because of its high temperature stability. As the major mineral reserve for molybdenum, molybdenite (MoS 2) is commonly found in porphyry copper deposits. Molybdenite is naturally floatable and can be separated from copper sulfide mineral using froth flotation.

Feed to the molybdenum flotation circuit is a bulk concentrate of 27% Cu and 0.9% Mo at 55 to 60% -325 mesh produced with the use of sodium isopropyl xanthate, fuel oil, aeroprotnoter 3302, and …
About 99% of the metal molybdenum is derived from molybdenite (MoS 2; a sulfide mineral). Talc is one of the most common gangue minerals in molybdenite ores …
of molybdenum in descending order: China, the countries of Latin America, the USA. Molybdenite has excellent flotation properties compared to other sulfides, it can be cost …
According to our recent studies we have observed a new mineral of molybdenum with different float-ability which is corresponding to loss of …
1. Introduction. Common sulfide mineral collectors are known to adsorb onto molybdenite but these reagents are not necessarily effective for molybdenite flotation. …
The sulphide mineral suite was emplaced in a dominantly silicate rich host. At a flotation feed sizing of about 135µm P80, the liberation of the molybdenite, when assessed in two dimensions, was …
Recycling of petrochemical by-products is important for environmental protection and sustainable utilization of resources. In this study, petrochemical by-product was analyzed and used for the first time as a cost effective frother in flotation separation of molybdenum to replace terpineol. A significant improvement in molybdenum recovery …
The main mineral of molybdenum is molybdenite. The cycle of collective copper–molybdenum flotation includes the main flotation, control flotation, and three re-cleanings of concentrate.
