What can the collector play?

When it comes to mineral processing chemicals, I have to mention the flotation collector. What is the main role? What is its mechanism of action? What classification does it have? In order to help the users to use the flotation collector efficiently, our mineral processing pharmacy manufacturers will give you a detailed understanding.

The role of the capture agent is to capture useful minerals and improve flotation recovery. More detailed will be to change the hydrophobicity of the mineral surface, so that the minerals that want to float will float on the surface of the bubble to reach the purpose of mineral sorting.

The mechanism of action of the collector is:

The effects of collectors and mineral appearance are divided into: physical adsorption, chemical adsorption, and chemical reaction of appearance. The main methods are: physical adsorption of non-polar molecules, electric double layer adsorption, AC adsorption of the same name ions, molecular adsorption, chemical adsorption, adsorption of collectors in mineral appearance or pulp, and chemical reactions of appearance.

Classification of collectors:

Depending on the polar group of the agent and the mineral surface, the collector is further divided into: a thio compound collector, a hydrocarbon acid collector, an amine collector, and an oil collector.

Among them, the first two categories are also called anion collectors; the third category is also called cationic collectors; the fourth category is also called non-polar oils.

1. The representative agents of the thio compound collector are: xanthate and black medicine.

2. Representative agents of hydrocarbon-based acid collectors are: fatty acids and their sodium salts (including stearic acid, palmitic acid, oleic acid, linoleic acid, linoleic acid, tal oil, paraffin wax, oxidized stone soap) Hydrocarbyl sulfate and hydrocarbyl sulfuric acid (including sodium cetyl sulfate, sodium butyl naphthalenesulfonate, sulfurized petroleum).

3. The representative agents of the amine collector are: dodecyl primary amine and tetraethylamine chloride.

4. Representative agents for oil collectors are: kerosene, transformer oil, solar oil, wood tar, etc.

In recent years, new collectors with good effects and no toxicity (or less toxicity) have been presented from time to time, mainly including:

a, mixed toluene citrate. Yellow-white solid, is a collector of chlorinated ore, selected from cassiterite, black tungsten, antimony, antimony ore.

b, sulphur chloride No. 9. White powder, a powerful collector for non-ferrous metal sulfide ore.

c, sodium hydroxamate. White to yellow waxy solid, soluble in hot water, is a collector of oxidized ore. Such as flotation of iron oxide ore, copper oxide ore.

d, imidazole. Purple black powder, copper sulfide, nickel ore collector, collector for copper oxide ore can be higher than yellow drug, also used for flotation gold.
