    en.wikipedia.org/wiki/Sodium_ethyl_xanthate

    Sodium ethyl xanthate (SEX) [3] is an organosulfur compound with the chemical formula CH 3 CH 2 OCS 2 Na. It is a pale yellow powder, which is usually obtained as the dihydrate. Sodium ethyl xanthate is used in the mining industry as a flotation agent. [4] A closely related potassium ethyl xanthate (KEX) is obtained as the anhydrous salt.

    Triton X-100 is soluble at 25 °C in water, toluene, xylene, trichloroethylene, ethylene glycol, ethyl ether, ethyl alcohol, isopropyl alcohol, and ethylene dichloride. Triton X-100 is insoluble in kerosene, mineral spirits, and naphtha, unless a coupling agent like oleic acid is used.

  9. Froth flotation - Wikipedia

    en.wikipedia.org/wiki/Froth_flotation

    An example is sodium ethyl xanthate as a collector in the flotation of galena (lead sulfide) to separate it from sphalerite (zinc sulfide). The polar part of xanthate anion attaches to the ore particles and the non-polar hydrocarbon part forms a hydrophobic layer. The particles are brought to the water surface by air bubbles.
