Once you find gold in quartz ore, you can extract gold by the flowing steps: 1 Use a sledgehammer to break the rock into smaller pieces. 2 Place a steel anvil in a large pan to prevent the loss of the gold contained in the quartz stone. 3 Look for large pieces of gold that can be collected manually or with tweezers.

Cyanide Leaching. Let us consider the concentration of gold ore as an example. The crushed ore of gold is leached with aerated dilute solution of sodium cyanide. Gold is converted into a soluble cyanide complex. The gangue, aluminosilicate remains insoluble. 4Au (s) + 8CN – (aq) + O 2 (g) + 2H 2 O (l) → 4 [Au (CN) 2] – (aq) + 4OH – (aq)

Gold ore concentration process. The Crushing Sections: The gold ore from the mine site is always with size 0-400mm or 0-600mm after blasting. We use the crushing plant to crush the raw gold ore into 0-8 or 0-10mm. Primary Grinding and Classifying Section: The gold ore with the size 0-8mm or 0-10mm will be fed into the ball mill.

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 piled into heaps for extraction by cyanidation (see below). These heaps can be

Concentration Methods . This is a mining method that employs the processes that increase the concentration of gold in the ore by selectively removing the lighter materials. This is the most effective method when gold is found in rocks or other hard soils. First the rock containing the gold ore is crushed to decrease its grain size.

Gold extraction. Gold miners excavate an eroded bluff with jets of water at a placer mine in Dutch Flat, California sometime between 1857 and 1870. Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes

The ore is crushed to a size that will give good liberation of gold minerals. In most operations with this crushing stage, the ore is crushed until two-three inch. A finer size can be considered if the ore needs fine liberation. The leach cycle is normally from 20 to 30 days. When the leaching cycle is complete, a new crushed ore is piled.
