Hcl/ peroxide question Gold Refining Forum
With even stronger hydrogen peroxide we can end up changing all of the fine gold foils to dissolved gold plating back onto the copper yet undissolved, with these stronger oxidizers in solution less heat is needed to oxidize the chlorides to chlorine, with HCl and 30% H2O2 hydrogen peroxide we can dissolve gold in just a warm solution, in this Ok So I use teh hcl/peroxide and hcl/cl methods but was curious for the SMB in hcl/cl 1) what would be the result of using smb on hcl/perxide mix? and only like to see you post your gold buttons in the gallery Follow refining instructions for a process and you will see gold, wasting time on square wheels will loose gold and waste your time SMB reaction in hcl/peroxide and/or hcl/cl Gold Refining Small Scale Refining of Jewelers Wastes by Roland Loewen pg 175176 C1995 wrote: Hydrogen Peroxide and hydrochloric acid will dissolve gold This is used in several refineries One refiner reported that the recovery of PGMs was much improved when hydrogen peroxide rather than Will hydrochloric acid and hydrogen peroxide dissolve gold?Treatment of goldbearing ore with hydrogen peroxide during heap leaching of gold increases gold recovery by 12% and amounts to 5589%, without treatment 5469% This increases the Improvements in gold ore cyanidation by preoxidation with Sample decomposition is straight forward [1–10 g sample (roasted at 600–700 °C) + 5 g of MnO2 + 30 mL of 2 mol/L HCl] Gold is coprecipitated with potassium tellurite using tin (II) chloride (PDF) A method for leaching or dissolving gold from ores
Technical Note – Development in gold leaching using
African gold ore, obtained with H,OZ and compressed air as oxidants, are compared It is obvious that the kinetics of the gold extraction are greatly accelerated when using H,O, Table 1 — Average values of the gold extraction rate by cyanidation of a typical South African ore using HZOZ(adjusted to different 02 levels) and compressed air as It is known that gold can be efficiently leached from gold bearing ores using a mixture of hydrochloric acid, ferric chloride, and manganese dioxide12 The chemical reaction involved during the A Method for Leaching or Dissolving Gold From Ores or the partial pressure of HCl above the solution is 970 mmHg (1293 kPa) and the partial pressure of the water vapor is 184 mmHg (245 kPa), giving a total vapor pressure of 1538 kPa above the solution The dissolution of gold was measured gravimetrically weighing accurately the goldA Method for Leaching or Dissolving Gold from Ores or Regardless of how much gold might be present in our ore, unless the aqua regia (recommended over HCL Bleach when dealing with ore rather than jewelry scrap) can freely react with the gold present, we will spin your wheels and get “consistently inconsistent” results that Dissolving Gold and Precipitating Gold Pyrometallurgy *Cupellation is a refining process in metallurgy, where ores or alloyed metals are treated under high temperatures and controlled operations to separate noble metals, like gold and silver, from base metals like lead, copper, zinc, arsenic, antimony or bismuth, present in the oreGold Recovery Correctly : 12 Steps Instructables

the case of gold and silver the results were not that efficient either due to the low HCl concentration, which is the case of tests 1 to 8, or higher solid:liquid ratio associated with different reaction time, as pointed out in the tests 9 to 16, even with higher HCl concentration 146The refining of platinum is technically more challenging than gold or silver due to the lack of easily implemented electrorefining steps The separation from other PGMs is most commonly approached by dissolution of concentrates into HCl solutions (Figure 10)Electrorefining an overview ScienceDirect Topics The Largest Gold Refining Forum in the World The GRF combines many hundreds of years of experience in the precious metals industry We cover large fields including: karat/scrap gold refining, chemicals safety, electronic scrap refining, chemical and physical recovery methods, mining and metal detecting, bulding your own equipment, etcGOLD REFINING FORUM GOLD REFINERS HELPING Apply all safety gear correctly before working with chemicals and do this outside as the fumes are nasty Put the gold fingers and clean circuit boards in the coffee pot, in another container mix two parts muriatic acid and one part hydrogen peroxide and add to the coffee pot until it just covers the gold fingers and wait a week giving it a stir dailyGold Recovery : 8 Steps (with Pictures) InstructablesSmall Scale Refining of Jewelers Wastes by Roland Loewen pg 175176 C1995 wrote: Hydrogen Peroxide and hydrochloric acid will dissolve gold This is used in several refineries One refiner reported that the recovery of PGMs was much improved when hydrogen peroxide rather than Will hydrochloric acid and hydrogen peroxide dissolve gold?
