The Process of Extracting Gold The process of extracting gold from gold ores can be broken down into several stages Each stage involves a different process and requires different equipment and expertise Stage 1 Crushing and Grinding The first stage of the gold extraction process is crushing and grinding the gold ore to a fine powder >
·Problems related to the effective processing of refractory gold ores containing carbon and arsenic are discussed In the search for technologies for the extraction of gold from such ores including those obtained from the Sayak 4 gold deposit pyrometallurgical processing represents a possible direction The results of an experimental study of the Reducing
·The cost of reagent is reduced by recycling HCl from pyrohydrolysis step and iron raffinate from iron solvent extraction step to leaching stage P ilot scale and continuous bench testing of the MMS CN D cyanide destruction process on an Australian gold plant tailings effluent In Advances in gold ore processing ed Adams vol
·Currently the thiosulfate gold leaching operation at the Goldstrike mine Nevada of Barrick Gold Corp is the only large scale gold extraction plant with an alternate lixiviant Azizitorghabeh et al 2021 Although research on sulfur containing lixiviants has been the most common in gold hydrometallurgy in the past three decades few
·The broken ore is loaded into trucks or conveyor belts and transported to the ore dressing plant for processing Advantages It is cost effective for large shallow deposits and allows for quick extraction of large ore quantities Disadvantages It significantly alters the landscape and generates large amounts of waste rock Underground Mining
2 Sorting ore ore dressing The mined ore was brought to the ore dressing plant crushed with an iron hammer and ground into finer granules with a stone mill The ore was then placed in a water tub and sifted using a pan to separate the lighter sand from the heavier gold and silver
