  • Gold Chlorination Process by Miller

    Miller s Gold Chlorination process was introduced by F.B. Miller. The refining process employs chlorine gas which passed into molten gold covered with a layer of borax and silica and reacts with most of metals present in the molten charge. Platinum group metals do not react.

  • The Gold Smelting ProcessMelting Smelting Refining

    Jan 18 2017 · The most common gold refining methods include 1. Miller Process . This is a chlorination process that refines gold to a purity of about 99.5 . The process involves blowing chlorine bubbles through molten gold which reacts with metallic impurities forming a chloride slag that is separate from pure gold and floats on top.

    Miller Table Operation the design of our water table concentrator or "miller Table" is similar to a traditional sluice box but it operates entirely without riffles using a very thin layer of low velocity water. Our special matting has just enough "tooth" (roughness) to grab onto the fine gold while allowing the metered smooth laminar water flow to release the lighter weight sands.
