Indium(III) sulfate recovery_ Recovery price of indium plating solution_ Precious metal recycling and refining manufacturers

Indium(III) sulfate solution is a colorless liquid, which is usually used as the preparation of indium plating solution. Under heating conditions, metal indium or In2O3 is dissolved in a large amount of dilute sulfuric acid and concentrated at 50 ℃ to precipitate crystals of In2 (SO4) 3 · H2SO4 · 7H2O. Filter out the crystals using a glass sand core funnel, wash with glacial acetic acid, and then dry. Heat the prepared Acid salt until no more sulfuric acid volatilizes (450 ℃, about 6 hours), and then anhydrous Indium(III) sulfate can be generated. Indium(III) sulfate solution can also be prepared first, and then the solution can be concentrated and the rhombic crystal of In2 (SO4) 3 · 5H2O can be crystallized from it. The crystallization is heated at a temperature of about 500 ℃ for 6 hours to decompose to produce anhydrous Indium(III) sulfate. Waste Indium(III) sulfate solution is one of the sources of indium waste recovery. The recovery of indium waste also includes indium wire recovery, crude indium recovery, refined indium recovery, indium sheet recovery, indium ingot recovery, indium particle recovery, indium powder recovery, etc. If you have any demand for indium containing waste recycling, please call our 24-hour service hotline.
