摘要: Abstract The feasibility of using laser separation for rare earth recovery from coal ashes was explored. To do so, laser-induced motion and travel distances some oxides (Lu 2 O 3 , Yb HfO Dy Ta 5 Tm, Lu, Ho, TeO La TiO Fe Y GeO Sc ) mineral compounds (MgO, CaO, Al SiO KCl) that are commonly found is were numerically investigated. investigations carried out particles in quiescent air, ( T = 300 K, μ = 18.46 × 10 −6 N s/m ρ = 1.177 kg/m exposing to a CW beam 6 mm diameter it focused by 500 mm focal length lens. results showed the between these elements varied few micrometers several millimeters became widened as power increased. important result presented here all separated concentrated small area located near waist while other traveled further far waist.
