    06/04/2016· As the most efficient gold extraction technique of the time, it gained widespread popularity in the mining industry, and is still used by some mines today. Unfortunately, gold cyanidation was ineffective on refractory gold ores – which are made up of sulfide minerals that block the cyanide solution extracting the gold. An older, and very,

  • examples of gold processing techniques

    Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then

  • Gold extraction - QueensMineDesignWiki

    It is therefore critically important, that when evaluating gold extraction techniques, the ore deposit and the mineralogical factors are well known prior to making any decision (Marsden & House, 2009). Although there is a large set of mineral processing technologies to select from, the list is distinct (Stewart, 2012). The ore classification techniques however, are not distinct;
