Which collectors need to be used in the beneficiation reagent


  The collector selected for the beneficiation agent is a flotation agent that can change the hydrophobicity of the mineral surface and make the floating ore particles adhere to the bubbles. It is a very important flotation agent.

  1. Sulfide minerals such as copper, zinc, lead, and iron are related to gold, and sulfur-carbon compounds are often used as collectors in flotation. Such as alkyl (b, c, d, e, etc.) sodium disulfide carbonate (potassium), also known as xanthates, commonly known as xanthates. For example, in the flotation of gold-containing metal ores, ethyl xanthogenate and butyl xanthogenate are mainly used as beneficiating agents. Alkyl dithio LIN esters or their salts, such as (RO) 2PSSH, where R is an alkyl group, commonly known as black medicine.

  2. The mineral dressing agent collector is composed of JI groups that can interact with the surface of mineral particles and non-JI groups that play a hydrophobic role. When the trapping agent is adsorbed on the surface of the ore particles, the JI groups face the surface of the mineral particles, and the non-JI groups face outwards to form a hydrophobic film so that the ore level can float.

  3. In nature, except for graphite, coal, sulfur, and talc, most of them are hydrophilic, and so are gold mines. Adding a mineral beneficiation agent changes the hydrophilicity of the mineral particles, resulting in hydrophobicity that makes them float. Collectors usually include JI collectors and non-JI collectors.
