2011-3-15 Abstract. Liquid waste from Nong Son uranium ore processing is treated with concentrated acid, agglomerated, leached, run through ion exchange and then treated with H2O2 to precipitate yellowcake. The liquid radioactive waste has a pH of 1.86 and a high content of radioactive elements, such as: [U] = 143.898 ppm and [Th] = 7.967 ppm. In addition, this waste contains many polluted

2017-8-8 2.5. FTIR Spectrum. The infrared spectra of samples were recorded by Nicolet AVATAR370 FTIR spectrometer (USA) using the KBr disk technique. The quartz samples used for this purpose were ground in an agate mortar and pestle to pass 5 μm. 50 mg of samples was mixed with 30 mL distilled water in the absence or presence of 100 mg/L coagulant at pH 9 and 25°C.

2017-1-23 This kind of waste includes waste stones generated during mining and tailings. Waste stones mean wall rocks peeled off from major ore during the mining of metal and non-metal mines. Tailings mean the residue slag after distilling refining mines during mill run. (2) Industrial solid wastes from the metallurgical industry

2020-5-21 Improper mining waste disposal will lead to air, soil, and water pollution. Different types of mining include landfill mining, coal mining, oil and gas extraction, metal, and non-metal ore mining. In this article, we will look at different types of mining waste and how to manage it effectively. Types of Mine Waste 1. Rock or Solid Mine Waste

2021-1-4 Since management procedures are varied and specific to particular types of waste, it is very important to explicitly delineate and segregate waste streams at the outset to ensure they are appropriately identified and managed. The management of some hazardous or ‘controlled’ waste is regulated by specific treatment and disposal procedures.
