Gold extraction - Wikipedia
Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.Gold processing Britannica Exogenetic gold can also exist as oxidized ore bodies that have formed under a process called secondary enrichment, in which other metallic elements and sulfides are gradually leached away, leaving behind gold and insoluble oxide minerals as surface deposits.How Gold Is Mined Gold Mining Process World Gold Council 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.

Treatment of refractory gold ore whole ore and flotation concentrates has become more prominent since the 1980s, with many gold discoveries often including ores that are wholly or partially refractory. Refractory pre-treatment processes include pressure oxidation, biological oxidation and various forms of roasting.Gold Ores Processing Companies in the United States - Manta Gold, silver, Platinum group Ore processing facility for processing black sands, sulfide ore, or free milling concentrates through chemical leaching Klondex Gold and Silver Mining Company 4000 West Winnemucca Boulevard Winnemucca, NV 89445Gold Processing Methods and Gold Ore Extraction Of all the methods of extracting gold and processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets.
