The invention relates to a method for extracting gold through potassium ferricyanide. The method is characterized in that the gold is extracted from the auriferous ores under an alkaline environment at normal temperature and pressure with nontoxic ferricyanide serving as a gold leaching agent and calcium peroxide serving as a leaching adding agent; and the method is a completely novel cyanide

This was the first commercial method used for gold extraction. Place the ore into the mortar and grind it to the size of sand grains. Put the ore grains into a plastic bowl. Add the 35percent hydrochloric acid to the sodium hypochlorite bleach into a flask or beaker, in a twotoone ratio of acid to bleach. Ensure that the liquid mixture is at least six times the volume of the ore grains

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

· It collects the gold as water pushes the less dense components of the ore over the ridges. Dredging is the method by which a team of extractors funnel loose soil from the bottom of a lake or stream into a sluice box floating in a body of water. Less dense metals are pushed away as the gold sinks to the box''s base.

Removing the goldbearing rock from the ground is just the first step. 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 gravellike material then enters rotating drums filled with
