In mining, tailings or tails are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are different from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being proce…Read moreHome About What Are Tailings? Introduction Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings.Tailings.info What Are Tailings? - Their nature and productionBeneficiation includes crushing, grinding, gravity concentration and flotation concentration. Beneficiation is followed by processing activities such as smelting and refining. The beneficiation process begins with milling, which is followed by flotation for further beneficiation.Beneficiation - an overview | ScienceDirect Topicsاحصل على السعر
Comprehensive utilization of tailings is the process to develop and utilize tailings via multipath coordination with various technologies and equipment depending on the types and properties of tailings, in order to maximize the comprehensive benefits in the social, ecological, environmental, and economic aspects.This study investigated the recovery of nickel from tailings (0.2% Ni) obtained in a chromite beneficiation plant using H2SO4 leaching followed by oxalic acid precipitation. The tailings were characterized using mineral liberation analysis. Ni was found as Fe-Ni, Fe-Ni-Co sulfide minerals, which were encapsulated in serpentine, olivine, pyroxene and clinochlore. Liberated fine chromite ...Characterization of Nickel in Chromite Beneficiation Tailings by ...The extraction of metals during beneficiation is as follows: lead is 80–82%; zinc is 82–84%; silver is 60%; cadmium is 56%; bismuth is 32%. The rest of the useful components are lost in the tailings of beneficiation. The resulting wastes are fed to the tailings dump, located 9 km from the plant in the floodplain of the Ardon River.Tailings Utilization and Zinc Extraction Based on Mechanochemical ...احصل على السعر
Tailings are a by-product of mining. After ore containing an economically-recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream is termed “tailings”. Typically, mill tailings range from sand to silt ...Different approaches to tailings valorization can be taken, such as reprocessing to extract metals and minerals, tailings as backfill material, tailings as construction material, energy recovery and carbon dioxide sequestration (Lottermoser, 2011 ).Towards mine tailings valorization: Recovery of critical materials from ...احصل على السعر
