  • Using Ball Mills to Extract Raw Gold from Ores

    Jun 14 2018 · Hence a mill is a piece of equipment used to grind ores. Its major purpose is to perform the grinding and blending of rocks and ores to release any free-gold that is contained within them. At major mines the mill was the critical equipment that was required to process the ores that were extracted from deep underground. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill and impact from the hardened steel balls and the rock itself. In order to ensure that the rock is ground finely enough the SAG mill

  • Arrastras. Historic Gold Mining Method for Processing Ore

    The grinding process would continue allowing the mercury and gold to amalgamate. When the process was nearing completion several buckets of water were added to the arrastra suspending the lighter material that was then bailed out leaving just the small amounts of amalgamated gold at the bottom of the arrastra. Of all the methods of extracting gold processing it from its ore I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets.
