Mineralogical and geochemical characterization of the tailings

The flotation plant tailings, estimated at 4.5 million tons, are located in the urban area of the town of Boquira which has about 21,497 inhabitants (IBGE 2010). Several studies have addressed the pollution problem in the smelter region and its effects on the population living in the vicinity (de Andrade Lima and Bernardez 2017 ; de AndradeReprocessing tailings using flotation has proven to be more efficient and economical than other reprocessing methods, and the results indicate that reprocessing tailings not only benefits mining companies but also reduces the environmental impact of heavy metals (Lutandula and Maloba, 2013, Lv et al., 2015, Videla et al., 2016).Evaluation of the possibility of copper recovery from tailings

Associations of Gangue Minerals in Coal Flotation Tailing

The mass production of flotation tailings has become a serious risk to the environment. Re-concentration of tailings is one of the best ways to solve this problem, which requires a better understanding of flotation tailings. In the present work, flotation kinetics, timed-release flotation, X-ray diffraction (XRD), Fourier transform infrared The present article critically discusses all the factors that affect the flotation of platinum group element bearing minerals, flotation routes, essential gaps, the problems associated with their processing, and suitable reagent suites used in different ore deposits and plant practices.

Modern practice of laboratory flotation testing for flowsheet

A flotation testing system called FLEET was developed and validated with three cases studies being presented by Dobby and Savassi (2005). This system was designed to predict flotation plant performance using a standardised platform producing a set of timed concentrates which are sized into size classes before weighing and assaying.The reprocessing of tailings can have economic and environmental benefits compared to the processing of primary ore deposits. In this paper we present the characterization of a tailings dam in southern Chile by means of mineralogical and geochemical investigations, focusing on sphalerite and trace elements with the aim to Reprocessing of a Southern Chilean Zn Tailing by Flotation—A Case Study

The flotation of sphalerite mine tailings as a remediation

Abstract. Sphalerite tailings are the most important type of waste in the mining district of Sardinia. This situation justifies the interest in the applicability of flotation as a remediation technique by which declassify the tailings (reducing the concentration of heavy metals). The flotation of mine tailings represents a novelty if aimed atThe disposal of mill tailings is becoming a serious environmental problem with the increasing reagent concentrations (in particular collectors) in the flotation circuits. In this study, the acid-activated and aluminum-pillared bentonite adsorbents were synthesized and used for the removal of potassium amyl xanthate from the synthetic and realRemoval of the residual xanthate from flotation plant tailings
