    Taps are used to cut internal threads in a material. However not all threads are made with a cutting process. Roll Form taps are forced into a hole and the material is then formed around the tap. This works great for softer materials like aluminum copper brass and plastics. Thread mills are similar but can cut either internal or external Gold is processed by cyanide milling a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity according to Mineweb. Heap leaching is a less expensive method of gold extraction but it is a longer process and it recovers less gold than the cyanide milling process.

  • Free mill gold or not free mill Gold Prospectors

    Sean free mill is gold in it s free or elemental ( Native ) form and placer gold was once free mill lode ore before it was released by natural forces from the host rock. Non free mill is gold in chemical combination with other elements that does not look like native gold and requires leaching or smelting to separate the gold. The process works best when the ore is crushed to small pieces before roasting. this "burning" or roasting of the sulfide ores does work well to convert rebellious ores into a more free milling state allowing the values to be extracted. The addition of scrap iron to smelt mixes is a useful technique to small-scale operators
