The Mining Process | OceanaGold
The Mining Process. 1. Mining – Open Pit and Underground — To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
How Gold is Mined: The Process from Earth to Bullion
In-situ Leaching Method. Commonly called ISL mining. This process involves selectively dissolving near-surface gold deposits still in place within the ground. At operating sites, a leaching solution, typically made with alkaline chemicals like sodium cyanide, is injected through wells drilled into the permeable ore zone.
The gold mining life cycle
The gold mining life cycle. Step 1 (Surface) EXPLORATION. Prior to mining, exploration takes place to find gold-bearing ore in commercially viable concentrations. Geochemical and geophysical techniques are used to identify the presence of a buried ore deposit. Geologists drill to check mineral quality in identified locations.

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption …
The stages of mining: 5 lifecycle processes explained
The 5 Lifecycle Stages of Mining. 1. Exploration & Prospecting Stage. This is the first and most essential step of the mining process: in order to open a mine, companies must first find an economically sufficient amount of the deposit (an amount of ore or mineral that makes exploitation worthwhile.) Geologists are enlisted by the companies to ...

Autoclave Circuit & Gold
Slurry from the grinding circuit, at approximately 35% solids and 80—85% passing 135 mm is pumped to three thickeners. Thickener underflow, at approximately 54% w/w solids, is pumped to a train of four acidulation tanks. Sulfuric acid is added to the slurry to destroy sufficient carbonate prior to entering the autoclave circuit. Process air is ...

9 Step Process for Discovering, Mining & Refining Gold
Step #1 – Finding Deposits. The first step is discovering where gold deposits may be. Geologists use special 'geology' maps to look for promising areas to explore further. They examine physical and chemical characteristics of surface rocks to determine if any gold is in the ground beneath. Step #2 – Analysis of Promising Areas.
