WhatsApp: +86 18037808511Introduction. Gold is a very rare substance making up only ~3 parts per billion of the Earth's outer layer (imagine 1 billion smarties in one place and only 3 of them were made of gold!). Its rarity and physical properties have made gold one of the most prized of the Earth's natural resources. When gold is found in rocks it is almost always in ...
WhatsApp: +86 18037808511Carbonin leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain pregrobbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.
