Simulation and pilot experiments on pyrite concentrate separation in a Floatex density separator

A short review on hydraulic classification and its development in mineral industry

“…From the literature listed in Table 2, it is envisaged that, variables (a) and (b) are the most critical to achieve the particle classification or separation. Out of these two, teeter water flow rate and set point are the controllable variables whereas teeter bed height as well as teeter bed density are Few researchers were attempted to understand the particle separation inside the separation chamber by means of slip velocity models and relative velocity models [57,60,61,62,69,70,72,73] but the considered models are unable to address the complex dynamics inside the separation chamber like voidage gradient, size distribution and density particle gradient in the bed and retention time distribution of particles, which need to be incorporated. Moreover, there are several statistical designed experiments were carried out by using different material and empirical models were developed to analyze the performance [58,62,71,[74][75][76].…”

Investigation of classification alternatives for grinding circuits

“…The use of a hindered-settling column rather than a cyclone can result in a significant improvement in separation efficiency (Young 1999; Remes et al 2011; Ozcan 2020). Young (1999) tested a hindered-settling column in closed circuit grinding of sulfur minerals by replacing the cyclone and found it also contributed to subsequent savings in energy and water consumption.…”
