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.
Jan 23, 2012· As you can see, the process of taking metal ore from the earth and converting it to gold bullion is quite extensive and requires a lot front-end investment and time. In the end though, we get these shiny coins and bars to enjoy. Gold miners too take special care to make the impact of mining for gold as light as possible.
(cyanide leaching or cyanidation) by McArthur and Forrester in 1887 [2]. A basic flowchart for the recovery of gold from its ore is provided in Figure 1. Figure 1 Basic flowchart for gold recovery. The major categories of commercially viable recovery processes include the following [ 4, 5]: 1. Amalgamation (with mercury) 2.
One of the largest gold mines known worldwide is the Aurora Gold Mine located in Guyana, Africa. As of the year 2013, the Aurora Gold Mine has an estimated reserve of 6.54 million ounces. The Gold Mining Process. In addition to cyanide processing, gold ore is also processed with gravity separation.

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.
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.
amenability of an ore to the cyanidation process are gold leach efficiency and cyanide consumption as a function of the fineness of grind and other leach conditions. REFRACTORY GOLD ORE PROCESSES 'Refractoriness' results in poor gold recovery by standard processing techniques, and can be due to either chemical or physical interference. An
