    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 On average, it takes between 1020 years before a gold mine01/11/2021· The gold mining process is complex and goes beyond what most people imagine — miners in hard hats working underground or operating large, noisy mining equipment are images that often come to mind However, the actual mining of gold ore is only one step in a complex gold mining process Before miners can extract gold ore from the ground, extensive exploration and developmentGold Mining Process — From Exploration to Extraction, How29/02/2016· The processing of gold ores has traditionally made use of conventional crushing and grinding circuits In each case where gold is formed either as coarse native particles or in coarse grained sulphides, it is recovered by gravimetry concentration in the in the comminution circuit in addition to recovery of finer values by leaching Jigs are the most common types of gravimetric equipment placedGold Extraction & Recovery Processes
