    OverviewAction in solutionSafetyOccupational exposureEnvironmentSee also

    Ammonium lauryl sulfate (ALS) is the common name for ammonium dodecyl sulfate (CH3(CH2)10CH2OSO3NH4). The anion consists of a nonpolar hydrocarbon chain and a polar sulfate end group. The combination of nonpolar and polar groups confers surfactant properties to the anion: it facilitates dissolution of both polar and non-polar materials. ALS is classified as a sulfate ester. It is found primarily in shampoosand body-wash as a foaming agent. / Lauryl sulfat

    Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

    This paper presents the sulfidisation promotion effect of ammonium sulfate on the sulfidisation flotation of both malachite and copper oxide ores. Copper oxide ores are commonly difficult-to-float due to its molecular structure, and adding sodium sulfide as activator is necessary; however, its dosage to the flotation pulp must be strictly controlled, as it is also a powerful depressant

  • Sulfate Sulfur vs. Elemental Sulfur Part II

    The oxidation of elemental sulfur (S⁰) to sulfate sulfur (SO₄) in soil is a biological process and is carried out by several kinds of microorganisms. The rate at which this conversion takes place is determined by three main factors: 1. the microbiological population of the soil; 2. the physical properties of the S⁰ source; and 3. the environmental conditions in the soil.
