Numerical Simulation of Flotation Circuit for Kakoxene Ore Processing

摘要

A group of data from a batch flotation tests were plug into a batch flotation model,and mineral floatability parameters (flotation rate constant,mass fraction of floatability component) were derived from model calculation.Then a flotation circuit ofkakoxene ore was designed in JKSimFloat simulator,after inputting those floatability parameters to flotation circuit model,the ultimate grade and recovery of apatite was obtained by analog computation.Meanwhile,the same flotation circuit test was achieved in the laboratory.The apatite grade in concentrate is 66.61％ at the recovery of 78.35％ by simulation,while apatite grade in concentrate is 72.70％ at the recovery of 88.14％ in the laboratory tests.Compared with experiment data,the accuracy of simulation is acceptable.
