Precise Air Flow Measurement Improves Flotation Cell
The flotation cells required an air flow rate that varied from 35 to 1,050 SCFM depending on the location and production volume, and at pressures from 4 to 7 psig [03 bar(g) to 05 bar(g)] Typical process temperatures were 32°F to 140°F (0 to 60°C) Froth Based Models While the pulp phase is certainly important in the flotation process, the froth phase ultimately carries the collected solids into the concentrate: It is well known that the froth structure affects significantly the flotation performance, particularly the grade of the concentrate, and for a complete description of the flotation kinetics, the froth phase must be consideredThe effect of surfactant concentration on batch S T Diagnosis of concentrate grade and mass flowrate in tin flotation from colour and surface texture analysis[外文期刊] 1997(06) 24LIANG Ruilu;SHI Daxin Carrier floatation of ultrafine cassiterite particles and its mechanism 1990(03) 本文读者也读过(10 从锡尾矿中回收有价金属的进展及相关建议图文百度文库

It was further observed that desliming resulted in improved flotation rates for the sulfide minerals For a flotation time of 3 minutes, recoveries of 69% and 74% were obtained with elutriation and sieving respectively compared to 58% recovery for baseline testsHargrave JM, Hall ST (1997) Diagnosis of concentrate grade and mass flowrate in tin flotation from colour and surface texture analysis Miner Eng 10:613–621 CrossRef Google Scholar [71] SadrKazemi N, Cilliers JJ (1997) An image processing algorithm for measurement of flotation froth Multivariate Image Analysis in Mineral Processing Flotation cells require precise control of compressed air because the frothing process efficiency is based on the speed of the froth as it moves from the surface of the slurry to the recovery area The speed of the froth is controlled by the air bubbles induced into the flotation cell, tank level and reagent dosagesPrecise Air Flow Measurement Improves Flotation Cell
