Tailings Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses waterget price

Dry Processing Vale

For the dry treatment, no water (from the environment) is required to process the extracted ore; thus, there is no need to build tailings dams. In comparison to the wet processing, the dry processing technique reduces the total water consumption by 93%, on average.get price
