| titleOfInvention | Collecting agent and preparation method and application thereof |
| abstract | The invention discloses a collecting agent preparation and application method. The collecting agent is prepared from modified dithiocarbamic acid, sodium mercaptobenzothiazole, lauryl mercaptan and fatty alcohol. A molecular formula of the sodium mercaptobenzothiazole is shown as a formula I, a molecular formula of the modified dithiocarbamic acid is shown as a formula II, and a molecular formula of the lauryl mercaptan is shown as a formula III, wherein R1 refers to straight-chain alkyl groups with 1-4 carbon chains, and R2 refers to straight-chain alkyl groups with 2-4 carbon chains. The preparation method includes that the modified dithiocarbamic acid, the sodium mercaptobenzothiazole, the lauryl mercaptan and the fatty alcohol are mixed proportionally and mechanically stirred for 10-30min at the temperature of 15-35 DEG C to obtain reddish brown oily liquid which is the collecting agent. The collecting agent is applicable to associated precious metal sulfide flotation. Recovery rate of useful metals in associated precious metal sulfide ores can be increased by giving full play to synergistic effects of different collecting agents. |
