Polymetallic Sulfide Particle Hydraulic Lifting Performance Simulation

Polymetallic sulfide particle hydraulic lifting process was simulated with theoretical analysis and numerical calculation. Simulation goal was to obtain polymetallic sulfide particle hydraulic lifting conditions in vertical pipe and action rules between hydraulic lifting system parameters and hydraulic lifting performance. Mechanics analysis model of polymetallic sulfide particle hydraulic lifting was established. Vertical pipe polymetallic sulfide particle hydraulic lifting process solid-liquid two-phase flow motion simulation model based on FLUENT software was established. Maximum concentration distributions of particle phase in lifting process with different system parameters were simulated. Simulation results are as follows: polymetallic sulfide particle hydraulic lifting performance is increased with water phase initial velocity increasing, polymetallic sulfide particle hydraulic lifting performance is decreased with particle diameter increasing and particle phase initial concentration increasing. There exists a hydraulic lifting threshold velocity v₀ in polymetallic sulfide particle hydraulic lifting process. Polymetallic sulfide particle hydraulic lifting process can´t be realized smoothly when v_w<;v₀ . Polymetallic sulfide particle hydraulic lifting process can be realized smoothly when v_w≥v₀.
