Phosphorus is normally produced by mining and beneficiation of Phosphate ores. 3 Mines produce large amounts of waste including toxic metals and radioactive elements. 4 The mining and beneficiation process results in the majority of these hazardous elements being lost either to waste disposal or to the environment, mainly …
The improper disposal of such waste causes negative impact on the environment. One such waste which is generated during the beneficiation process of iron ore is waste iron ore tailings, which is also termed as IOT. Further, dumping of IOT on open ground creates huge dumping sites.

Recovery Act (RCRA) as it applies to mining waste was amended in 1980 when Congress passed the Bevill Amendment, Section 3001(b)(3)(A). The Bevill Amendment states that "solid waste from extraction, beneficiation, and processing of ores and minerals" is excluded from the definition of hazardous waste under Subtitle C of RCRA (40 CFR …
Enormous amounts of fines are produced both from the natural geological process as well during the mechanized mining operations which is hitherto in unknown resource present in the form of waste. Beneficiation and utilization of these fines/tailings still remains a challenging task.

Phosphate rock mining, beneficiation, and processing waste; Uranium waste; Utility waste (i.e., fossil fuel combustion waste) These wastes typically are generated in large volumes and, at the time, were believed to possess less risk to human health and the environment than the wastes being identified for regulation as hazardous waste.

4.1 Internationally. Beneficiation is a common practice internationally. Fly ash and boiler ash are currently being used as an integral part of the cement manufacturing process (Pacheco-Torgal 2017).This process demonstrated that there were little or no significant negative impacts from the use of these products in the manufacture of cement.

Note: (i) Power plants up to 15 MW, based on biomass and using auxiliary fuel such as coal / lignite / petroleum products up to 15% are exempt. (ii) Power plants up to 15 MW, based on non-hazardous municipal waste and using auxiliary fuel
RCRA states that "solid waste" means any garbage or refuse, sludge from a wastewater treatment plant, water supply treatment plant, or air pollution control facility and other discarded material, resulting from industrial, commercial, mining, and agricultural operations, and from community activities.
Review of the research works. The critical issues related to the chromite process plants investigated by various researchers have been categorized as: 5.1. Reducing the tailing losses (9–20% Cr 2 O 3 ). 5.2. Beneficiation of low and sub-grade chromite ore (10–30% Cr 2 O 3 ). 5.3.
Plan for emergencies – handling hazardous waste leaves room for emergency situations caused by mistreatment of the waste or any other cause. Plan for emergencies in the following ways: Maintain spill and appropriate emergency response equipment in an accessible area.

EPA segregated extraction and beneficiation wastes from processing wastes. EPA submitted the initial results of these studies in the 1985 Report to Congress: Wastes from the Extraction and Beneficiation of Metallic Ores, Phosphate Rock, Asbestos, Overburden from Uranium Mining and Oil Shale(U.S. EPA, 1985).
Hazardous Waste . Component of the waste stream which by its characteristics poses a threat or risk to public health, safety or the environment (includes substances which are toxic, infectious, mutagenic, carcinogenic, teragenic, explosive, flammable, corrosive, oxidising and radioactive). Hazardous wastes are generally unsuitable for landfill
As on today, there is nearly 125 million tones of accumulated unutilized fines at various mines and generation of about 8 million tones of slimes (below 0.2 mm) annually containing 14-60 % Fe ore lost as tailings in beneficiation / washing plants. In Orissa, approximately, 5.5 million tons of iron ore fines are produced per year.
