Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly.

Draw a flow sheet or block diagram for a hydrometallurgical process treating a simple gold ore containing only free milling native gold less than 200 microns in particle size within a simple silicate matrix. Include the milling circuit, leach, carbon adsorption, elution, and carbon regeneration stages.
Diagram Of Gold Mining Processing Gold mining was first carried out in alluvial areas. Processing system is also very simple to do that is by panning using a tray, which then developed with gold mining wave table, and followed by gravity separation method using the amalgamation process with the capture of .
facility. It is intended to provide an understanding of the main gold ore processing technologies and their associated inputs and emissions. Facilities will have their own process flow diagrams and these should be used to facilitate emission estimation and NPI reporting requirements. Gold ore processing includes the following steps.

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.
