1978-7-1 · INTRODUCTION Sixteen years ago Arbiter and Harris (1962a) suggested a two-phase model of the flotation machine attempting to account for kinetic behaviour, both transient and steady state. The two-phase model is illustrated in Fig. 1 using Harris and Rimmer's (1966) terminology, and models having additional phases are shown in Figs. 2 and 3

1975-3-1 · Residence time measurements were made on a Denver laboratory flotation machine with and without the DR ring assembly. Soluble and insoluble tracers were used (a dye and fine quartz, respectively), and the variables studied were tank liquid volume, V, water and air volumetric flow rates, Q and Q A respectively, and some geometric and design variables

flotation bubble delineation based on harris corner

Froth image segmentation is an important and basic part in an online froth monitoring system in mineral processing. The fast and accurate bubble delineation in a froth image is significant for the subsequent froth surface characterization. This paper proposes a froth image segmentation method combining image classification and image segmentation. In the method, an improved Harris

2021-3-14 · The technical indicators of flotation mainly depend on the performance of the flotation machine provided that other flotation conditions are determined. Therefore, the fluid dynamics state of the flotation machine tank should meet the requirements of the flotation process for different mineral particles in order to improve the mineral flotation

In flotation, depressants are used to reduce the amount of gangue that reports to the concentrate and hence increase the selectivity of the flotation process. At the University of Cape Town extensive batch flotation tests are carried out to evaluate industrial depressants and standard procedures have been developed over the years. This study was conducted in order to develop an improved method

The Kansanshi mixed copper sulfide-oxide ore contains significant proportions of fine material manifesting in a variety of processing challenges. This paper presents the work which was carried out to evaluate the efficacy of desliming in improving the flotation response of the ore. Two modes of desliming were investigated, namely; sieving and elutriation after which the deslimed material was
