The initial step in the gold refinery process involves the extraction of gold ore from the ground. This is done through mining methods that depend on the location, accessibility, and quality of the ore deposit. Underground mining techniques, such as tunneling and shaft mining, are employed to extract gold ore from deep within the Earth.

The gold beneficiation process is gravity separation, flotation, magnetic separation, cip, cil, heap leaching and other combined methods. Alluvial/Placer gold process: The gold concentrate of placer gold ore has a high content and mostly exists in the form of sand grains. Therefore, gravity separation is often used when sorting. After pretreatment, …

The other significant gold producer in India has been the Hutti Gold Mine, located in the Raichur district of Karnataka. 4 The operation initially entered production in 1902, although it subsequently closed in 1918 because of a paucity of funds due to World War I.
