The oxidized ore collector generally consists of a polar group and a non-polar group. The polar group contains atoms such as oxygen and nitrogen, and the non-polar group has a large molecular weight.
The anionic collectors are: fatty acids and soaps thereof, oxidized paraffin soaps, and terrestrial oils.
The cationic collectors are: a first amine, an alkylpyridine, and the like. A second amine is often mixed in the first amine.
Hydrocarbon oil collectors are classified into aliphatic hydrocarbons, alicyclic hydrocarbons and aromatic hydrocarbons. Because they are hardly soluble in water and cannot be dissociated into ions, they are also called non-polar collectors and neutral oil collectors. Such applications more collectors coal oil, transformer oil, diesel oil and fuel oil. Followed by tar, heavy oil, medium oil and so on. Non-polar minerals with good natural buoyancy, such as graphite , molybdenite , kerosene, etc., can be used as collectors alone. Flotation gold is often used to improve the selection index. In the flotation of sulfide ore and oxidized ore, it can be mixed with other collectors, which not only can improve the flotation index, but also reduce the dosage of the agent.
