minerals such as chromite, if present as is the case here see below, play a significant role in dictating the transport, distribu-tion, bioavailability, and toxicity of Cr in the environment. These phenomena will be particularly critical in areas around mine tailings and chromite
Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and ...

Jan 01, 2016 Waste is a source of secondary raw materials but it can negatively affect the natural environment and public health Rao et al., 2010. Flue dust generated from the ferrochrome industry is one such type of waste containing chromite minerals. The toxic nature of trivalent and hexavalent Cr makes flue dust from the ferrochrome industry hazardous.

At paddy elds located near the mine tailings, the total contents of Cr, Co and Ni were 5,750, 375 and 5,590 mg kg1, and the contents of theirwater-extract-
26 ABSTRACT 27 Risk assessments that take into account the formation of environmentally dangerous hexavalent 28 chromium in Cr-containing mine tailings, and associated soils and sediments, require an 29 understanding of the occurrence and speciation of Cr in silicate minerals and glasses. Silicates 30 are more soluble and generally more susceptible to weathering than the refractory mineral
Dec 19, 2016 Increasing population levels, growing economies, rapid urbanization and changes in consumption patterns have increased the demand for raw materials such as base and precious metals, leading to growing concerns regarding their availability and the global efficiency of the mine supply chain. Mine tailings, consisting of process effluents that are generated in a mineral processing plant, are ...
Dec 15, 2010 Mine tailings are the ore waste of mines, and are typically a mud-like material. Worldwide, the storage and handling of tailings is a major environmental issue. Many tailings are toxic and must be kept perpetualy isolated from the environment. Scale of tailings production is immense, since metal extraction is usually only ounces or pounds, for ...
Aug 10, 2018 Tailings can reach immense proportions, appearing in the form of large hills or sometimes ponds on the landscape. Tailings deposited as large piles can cause a variety of environmental problems ...

May 15, 2017 Exposure of mine tailings to both oxygen and water facilitates the microbially-catalysed oxidative dissolution of the sulfide minerals they contain, generating acidic waste waters that contain elevated concentrations of dissolved metals and sulfate. Acid mine drainage AMD is a widely-reported environmental pollutant, with global distribution.
Large tonnages of chromite tailing were discarded during processing of chromite ore in the conventional circuit. A typical chromite plant tailing was treated in wilfley table for the recovery of chromite values. Optimisation study was carried out for the process parameters of wilfley table using empirical models, developed from the experimental data.
Oct 06, 2020 New Tailings Reprocessing Technology Has Environmental Benefits. Tailings, mineral waste products produced by mining operations, are a well-known pollutant requiring remediation. Tailings may be dumped in or near water or transported by wind or water to contaminate the surrounding area. Mine sites typically manage tailings by constructing ponds ...
Increasingly stringent environmental regulations and industry adoption of waste minimization guidelines have thus, stimulated the need for the development of recycling and reuse options for metal related waste. This book, therefore, gives an overview of the waste generation, recycle and reuse along the mining, beneficiation, extraction, manufacturing and post-consumer value chain.
Chromite beneficiation operations in Sukinda valley India produce large amounts of tailings, which are stored in open air. In this study, bioleaching experiments were carried out in batch reactors with Acidithiobacillus thiooxidans or Pseudomonas putida in order to determine the potential leachability of metals contained in these tailings due to biological activity.
