how g is mined g mining process world g councilsep 03, · the lifecycle of a g mine. people in hard hats working underground is what often comes to mind when thinking about how g is mined. yet mining the ore is just one stage in a long and complex g mining process. long before any g can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the depositnuclear fuel cycle' extractingg uranium from its oresacid leaching uranium ores vary significantly from deposit to deposit and each mill must be designed to fit the specific characteristics of its ore. the general process, however, is similar for many ores, variations of the acidleach flowsheet shown in figure 1 have been used in more than nulls. the basic steps in this flowsheet aresummary of g plants and processes sciencedirect269 rows· jan 01, · the general principle behind the structure of the volume is that of flow
