متن کاملConcentration and recycling of rare earth elements (REEs) from iron mine waste using a combination of physical separation methods
This study aims to investigate and optimize the effects of the main parameters including the particle size, gravity and magnetic separation combination, high gradient magnetic separation, magnetic field intensity, shaking table slope, washing water flow, and electrostatic separation upon the rare earth element (REE) recoveries from iron mine waste. The electron microprobe showed that high amoun...
متن کاملRare Earth Elements Profile
Definitions and characteristics The rare earth elements (REE) (sometimes referred to as the rare earth metals) are a group of 17 chemically similar metallic elements, including the 15 lanthanides, scandium and yttrium. The lanthanides are elements spanning atomic numbers 57 (lanthanum, La) to 71 (lutetium, Lu) (Table 1). The lanthanides all occur in nature, although promethium, the rarest, only...
متن کاملA multifactorial analysis of radon exposure and lung cancer in the Middle Urals, Russia
n 1987 the International Agency for Research of Cancer (IARC) evaluated radon and its decay products as human carcinogens (1). Large epidemiologic studies conducted in Western Europe in the Õ90s showed that this radioactive gas accounted for 50 to 90% of a radiological dose (2). Very high residential concentrations of radon were measured in Sweden and Finland (3-5). They were 5,000 times higher...
