FLOTATION COLLECTORS

Flotation collectors were mainly identified as Anionic Collectors, these are fatty acid based compounds which, such like Tall Oil Fatty Aicd (TOFA). And Cationic Collectors, are typically amine-based compound, such as Gum Rosin Amine. Anionic collectors can used in the flotation of phosphate and oxide minerals. Cationic collectors can used in the flotation of quartz or silicates.

Gum rosin and the derivatives chiefly consist of resin acids, especially abietic acid, which capable of in the flotation of Hematite, Magnetite and Goethite. The derivatives can neutralize to sodium soap with caustic soda, such like DERCINATE™ 70D, a rosin soap was produced by DRT. TOFA can applied in anionic collectors, react from TOFA as pentaerythritol ester of tall oil fatty acid, such like RESINOLINE™ E500 from DRT, a foaming agent for mineral flotation.

Gum rosin amine is the other important ingredient of flotation reagents, it can react a separation of Pyrocholore from Calcite or react a separation of SiO2 from Apatite.(Herbert G Burks, Brit, 800717, 1958). Another general product is Roins Amine D™, a rosin amine acetate produced by PDM Inc. This series contains Dehydroabietylamine about 55%, Dihydroabietylamine about 15%, Tetrahydrobietylamine about 15%, Pimaricamine about 8% and Isopimaricamine about 7%.

PINE BASED CHEMICALS ON FROTHERS/SURFACTANTS


On mining chemicals, Turpentine Oil is a key frother, we call it as “Number.2 Oil” in China. It natural contains of Terpineol, which was reacted a hydration and dehydration from alpha-Pinene and beta-Pinene. Turpentine oil was general identified as Gum turpentine, Crude sulfate turpentine (CST) and Wood turpentine. It’s a by-product of paper making in North America, they are using CST as the mainly material of frothers.

THE FOAMING PROPERTY

Frothers effect the quality and number of bubbles. They also influence the touching between mineral particles, which would increase the adhesion of hydrophobic mineral particles touch on small and rich foam, so that separate of hydrophilic particles.

Terpineol has a rigid structure in an Alcoholic hydroxyl and compounds with a six-membered ring containing a double bond. It has better stability than Linear alcohol. The structure reduces flexibility of bubble wall and keep foam maintaining the shape. See figures as below, comparing with other alcohols, Terpineol has moderate height of foam and better half-life at different concentrations.

WE SUPPORT YOUR INNOVATION

Pine based chemicals have sustainability and possibility. Let’s work together!
