“…A better separation is observed for the higher slurry flow rate of 2.3 m 3 /h. A similar observation has been reported for other spiral designs for treating low-grade chromite and hematite ores [10,11,42]. The separation efficiency improves with increasing the feed velocity due to the enhancement of the centrifugal force acting on the particles.…”

The low chromium‐to‐iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium‐to‐iron ratio. Also, detailed characterization studies including automated mineralogy were carried out to better understand the nature of the samples. Enhancing the chromium‐to‐iron ratio was achieved by using advanced spiral separators which will be discussed in this paper.

“…Central composite design is a statistical mathematical method widely used in engineering problem analysis and modeling. It can be used for the nonlinear evaluation of between operating parameters and indexes, and then operating conditions can be optimized by the response surface [17]. In this paper, the classification experiment of compound hydrocyclone was carried out by central composite design method.…”

Compound hydrocyclone is a kind of dynamic hydrocyclone also with the advantages of static hydrocyclone. In this investigation, the effect of operating parameters on separation performance of compound hydrocyclone is studied using both CFD technique and experimental method. The flow field of compound hydrocyclone was simulated by the RSM turbulence model; the particles with different size were simplified to 6 phases and simulated by the mixture multiphase model. The central composite design method was used to conduct the separation experiment of compound hydrocyclone. The results indicated that compound hydrocyclone can be used for finer particles separation and the flow field of compound hydrocyclone can still achieve a higher centrifugal force in lower inlet velocity. When the minimum partition size is required, the optimized operating condition of the compound hydrocyclone is v = 2.5 m/s, n = 1865 rpm, and c = 7.5%, while when the maximum partition size is required, the optimized operating condition is v = 2.5 m/s, n = 905 rpm, and c = 24.5%.

“…The pressure drop across the axial cyclone is less than that in the tangential flow cyclone. Experimental results show that the axial cyclone can maintain high separation efficiency only in high gas volume fraction, in which the flow of the gas-liquid two-phase mixture is relatively stable (Matsubayashi et al, 2012;Dixit et al, 2015). However, when the gas-liquid mixture before entering the separator is in unstable flow pattern, the separation efficiency drops sharply (Xiong et al, 2013(Xiong et al, , 2014Funahashi et al, 2016).…”

Gas-liquid separation technology is widely used in various fields of industrial production. In this research, a new kind of gas-liquid separator was proposed for the separation of gas-liquid mixture under different flow patterns. An inclined experimental system with an angle of 60 degrees from the vertical was established to test the new designed gas-liquid separator using of water and air as the working fluid. The experiment was conducted with the water flow rates covering 2.85-4.17 m 3 /h and the gas volume fraction covering 5-90%. Experiment results show that the separator can enable high efficient separation of gas-liquid mixtures under different patterns, especially under unstable flow patterns. The liquid level inside the separator is an important factor affecting the performance of the separator. On the basis of this, the critical liquid level of the separator was proposed for the practical application of the separator. This study fills the gap in the field of gas-liquid separation and provides a method for the separation of gas-liquid mixtures under different flow patterns.
