1. Introduction. Froth flotation is an important and versatile separation technique in the mineral processing industry for recovering valuable minerals from mining ores (Aghazadeh et al., 2015).Froth flotation is a physico-chemical separation process based on the differences between the surface wettability of valuable and valueless components (Wills and Finch, 2015).
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 blend the …

1. Crushing and Grinding: Crushing and fine-grinding the gold-bearing ore into the appropriate particle size for better separation of gold in the subsequent flotation process. 2. Flotation: The finely ground ore slurry is mixed with a flotation agent. The flotation agent type and amount will be selected according to the specific ore properties.
This process generally includes 4 processes: Grinding and dissociation: the ore is ground first to dissociate useful minerals from other minerals or gangue minerals; Slurry adjustment and dosing: adjust the pulp concentration to meet the flotation requirements, and add the required flotation reagents to improve efficiency; Flotation separation ...
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on …

Flotation separation of chalcopyrite from molybdenite was studied using seaweed glue (SEG) as a depressant. Flotation process and mechanism were examined by response surface methodology, flotation tests, adsorption tests, zeta potential measurements and fourier transform infrared (FT-IR) spectra. Response surface methodology with a Box–Behnken design …
Molybdenum is a good conductor of electricity and heat because of its high melting point, boiling point, hardness and density. It is often used in the production of alloy additives, stainless steel, tool steel, temperature-resistant steel, etc. According to the excellent natural floatability of molybdenum ore, flotation method can be selected for treatment.
