  1. What Chemicals Are Used in Gold Refineries? Gold refineries face challenges in processing raw gold. Complex impurity removal requires precision and expertise. Industry experts understand the need for precise chemicals. Refineries must navigate strict environmental regulations.

  2. Primary Acids and Solutions Hydrochloric Acid Nitric Acid Aqua Regia Sulfuric Acid Dissolves base metals while preserving precious metal content. Removes silver and platinum group metals efficiently. Completely dissolves pure gold due to its unique properties. Helps eliminate remaining traces of base metals.

  3. Precipitating and Reducing Agents Sodium Metabisulfite Ferrous Sulfate Creates pure gold precipitation from chloride solutions. Serves as an alternative precipitant in specialized processes. Sodium Nitrate Oxalic Acid Maintains oxidizing conditions during metal reduction steps. Produces high-purity gold precipitate for industrial uses.

  4. Neutralizing Agents Urea Sodium Hydroxide Sodium Carbonate Breaks down excess nitric acid without affecting dissolved metals. Neutralizes strong acids in spent solution treatment. Provides pH balance in final waste processing.

  5. Fluxes and Melting Agents Sodium Tetraborate 2 Helps separate unwanted oxides from molten precious metals. Borax 1 Creates protective barriers to prevent oxidation during melting. Potassium Nitrate Acts as an oxidizing agent in flux mixtures. 3

  6. Gold Refining Techniques Aqua Regia Dissolution 1 Breaks down gold into soluble chloride compounds. Miller Chlorination 2 Removes base metals through chlorine gas treatment. Wohlwill Electrolysis 3 Achieves highest purity levels for industrial applications.

  7. Other Important Chemicals Potassium Cyanide Zinc Powder Chlorine Gas Selectively dissolves gold in large-scale operations. Precipitates gold from solution with high recovery rates. Removes base metals through controlled oxidation reactions.

  8. Safety Protocols Personal Protective Equipment Must meet international safety standards. Emergency Shower Stations Require monthly testing and maintenance. Ventilation Systems Operate continuously during chemical processing.
