  • Recovery of gold in iodine-iodide system – a review

    Iodide could serve as an effective mean for recovering through the dynamic, thermodynamic and electrochemical assessment. And a series of parameters, such as oxidants selection, the /iodide ratio, solid-to-liquid ratio, acidity pH and time, affect the

  • A Method for Leaching or Dissolving Gold from Ores or

    lurgical extraction routes utilize a step to produce a -bearing solution as an intermediate product while the recycling of secondary from electronic and precious metal scrap is based on the selective and fast dissolu-tion of the precious metal. Therefore, A Method for or Dissolving from Ores or Precious

  • Heap leaching a stack of gold | MiningFeeds

     · Heap is used to extract , copper, silver, uranium, and . This method was first employed to extract copper at the Bluebird mine in the US in the early 1960s, and then by several mines in the western parts of the US a few years later. Since then, heap has been adopted successfully by many mines across the world

  • Using Leach On Ore For Gold Recovery - Gold Recovery

     · Its what got me started expeirimenting with the iodide .I went from there to doing web searches on and the other halides. ... / iodide solution is a difficult and messy process, and the summary by Dr. Williams on the ICMJ website is correct, but far from complete, and in fact leaves out a lot

  • Gold cyanidation

    Although cyanide is cheap, effective, and biodegradable, its high toxicity has led to new methods for extracting gold using less toxic reagents. Other extractants have been examined including thiosulfate S 2 O 3 2−, thiourea SCNH 2 2, iodine/iodide, ammonia, liquid mercury and alpha-cyclodextrin. Challenges include reagent cost and the efficiency of gold recovery

  • Iodine 7% Leach for Gold - Gold Refining

     · Gold-Digger Iodine leach goes to work immediately on Gold, then Platinums, then Silver, in that order. It tends to ignore the other "Trash" metals. Naturally, it is about PH 4-5, and is kept there, especially in the presence of Alkali metals, by adding small amounts of HCL acid. Typically 24-48 hours to collect fine gold

  • US7582136B2 - Recovery of gold from potassium iodide

    A process for the recovery of from a potassium iodide- solution is provided. The is precipitated from the solution using a weak acid, e.g. ascorbic acid, a buffer, e.g. sodium bicarbonate, and a dye. The precipitate is then removed from the solution resulting in the recovery the precipitate and the potassium iodide- solution

  • Iodine Gold Leaching

    Over the last few years there has been an intense effort to identify lixiviants other than cyanide for and silver . Bromide and iodide also exhibit the ability to form polyhalide complexes. This characteristic promotes the dissolution of Br2s and I2s in aqueous solution
