  • Flowsheet Options - Flowsheet Options | Albion Process

    Flowsheet Options. For the processing of a refractory gold/silver concentrate, the pH of the oxidative leach is held at 5.5 by the continual addition of limestone slurry to ensure complete oxidation of the sulphur to sulphate. The oxidised residue can then be fed .

  • The Effects of Oxidation on Copper | Sciencing

    Oxidation Defined. Oxidation occurs as a result of copper's exposure to air, though water --- especially salt water --- heat and acidic compounds can also induce corrosion. Oxidation adds a verdigris color (blue-green) to copper or copper carbonates like brass or bronze.

  • CESL Process - Teck

    Example: Oxidation of chalcopyrite (6CuFeS 2 + 7.5O 2 + 2H 2 SO 4 + 2H 2 O -> 2[CuSO 4 2Cu(OH)2] + Fe 2 O 3 + 12S°) The sulphur and the hematite (Fe2O3) solids do not leach or react in the subsequent stages of the CESL Process and are disposed of in their current forms as tails.

    pressure oxidation (POX) technologies. By combining the two technologies, the majority of the sulphide sulphur present in the concentrate (approximately 70%) could be oxidised with air by applying the BIOX ® process. This left a relatively small portion of the sulphides to be oxidised with oxygen in an autoclave to complete the oxidation and precipitate the arsenic. The BIOX ®

  • Treatment of membrane filtration concentrate of coking ...

    Coking wastewater concentrate (CWC) generated during the membrane filtration process is difficult to treat mainly due to its higher chloridion concentration. Advanced oxidation process is ineffective in treating CWC because of the quenching effect of chloridion on hydroxyl radicals.
