  • Ferric Chloride brine Leaching of Galena Concentrate.

    The procedure involves leaching galena flotation concentrates with ferric chloride (fecl3) solution to obtain lead chloride (pbcl2) and elemental sulfur as expressed by the following chemical reaction pbs + 2fecl3 gt; pbcl2 + 2fecl2 + s deg. At 100 deg c, over 99 pct of the pbs in the concentrate is converted to pbcl2 in less than 15 min.

  • UNITS OF CONCENTRATION Vancouver Island University

    The number of milligrams of solute per kg of solution = one ppm, since 1 mg = 10 3 g and 1 kg = 103 g. Assuming the density of water is 1.00 g/mL, 1 liter of solution = 1 kg and hence, 1 mg/L = 1 ppm. This is generally true for freshwater and other dilute aqueous solutions.

  • Zinc smelting

    Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific
