what are the processes and machinery used to extract gold

  • Extracting Gold HowStuffWorks

    To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls. In these drums, the ore is ground to a fine slurry or powder.

  • Gold Processing Methods & Gold Ore Extraction

    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. This page offers a comparative review of gold recovery

  • Gold mining Wikipedia

    Gold panning is the easiest and quickest technique for searching for gold, but is not commercially viable for extracting gold from large deposits, except where labor costs are very low or gold traces are substantial. Panning is often marketed as a tourist attraction on former gold fields. Before large production methods are used, a new source must be identified and panning is useful to

  • How Is Gold Extracted From Gold Ore? Sciencing

    Several processes can then be used to separate the gold from the ore. The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a stone reaction which separates the gold from the ore. The gold is then removed from the solution with a filter press.

  • How to Extract Gold From Electronics : 11 Steps (with

    In this Instructable, I will show you how to extract gold from computers using products most people have lying around in their homes. The way I extract the gold is relatively straight-forward and pretty easy, but the chemicals used are very dangerous and should not be performed without proper knowledge and equipment. This process is not supposed to be lucrative.

  • Mining And Mineral Processing The Lithosphere Siyavula

    In ancient times mining and mineral processing were very primitive and the main method used to extract ores was digging by hand. Mining is largely divided into surface and underground mining. Minerals are often found in river beds, beach sands and other sandy areas. These are known as alluvial deposits. These minerals can be fairly easily removed by surface mining techniques. Other minerals

  • Processing, smelting and refining gold World Gold

    Gold refining. This refers to processes used to processes used to extract and separate the precious metals in mined material, doré, and from recycled products (jewellery and electronics). The main techniques used to remove the final impurities to create high caratage gold are summarised below:

  • Mining Gold Equipment Mine For Gold

    Mining Gold Equipment: These gold mining machines are definitely not for the hobby prospector. The Trommel is designed for high volume sorting of raw material. The refined, or classified, product is then run through a sluice box to further refine it. Very high levels of processing can be achieved with shovels aided by a trommel. It is essentially the same gold mining technology that is

  • How is gold found and extracted from mines?

    Smelting is the process of melting the negative terminals (with the gold attached) in a fiery furnace, usually at a temperature of 1500 degrees Celsius. A stone blend known as flux is added to the molten mixture to allow the gold to separate from impurities. Afterwards, the flux is drained away and the liquid gold is poured into bar-shaped moulds, and allowed to set. Once the gold bar is
