Types of collectors and representative agents

Posted on

Depending on the polar group acting on the surface of the mineral, the collector is further divided into: a thio compound collector, a hydrocarbon acid collector, an amine collector, and an oil collector. 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) Representative agents of thio compound collectors are: xanthate and black medicine.

2) Hydrocarbyl acid collectors Representative agents 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) A representative agent of the amine collector is: dodecyl primary amine, tetraethylamine chloride.

4) Oil collector Representative agents are: coal oil, transformer oil, sun oil, wood tar and the like.

In recent years, new collectors with good effects and no toxicity (or less toxicity) have emerged, mainly including: 1) mixed toluene acid. White solid, a collector, is selected from cassiterite, wolframite, tantalum, niobium ore mine chloride.

2) Sulfur Chloride No. 9. White powder, non-ferrous metal sulfide ore is powerful collector.

3) Sodium hydroxamate. White to yellow waxy solid, soluble in hot water, is a collector of oxidized ore. The flotation of iron oxide ore, copper oxide ore.

4) 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.

Electric Hoist, can be used indepently, or together with cranes, it has Wire Rope Electric Hoist and Electric Chain Hoist two types. It can travel rotation through the trolley hanging on the I-steel, and install on the Single Beam Crane, Gantry Crane , Jib Crane , overhang crane and monorail crane to rise and fall the cargos. So it can be used in factories, mines, wharf, warehouse, freight yards, and shops and so on which need lifting equipment for lifting heavy objects. Such as mining companies and railways, docks, warehouses. It is prohibited to manned.
