In this paper, we build an air conveyor with newly developed vortex bearing elements, and study the flotation precision of the front-end of the substrate in quasi-static flotation transport. We experimentally discuss the three influential factors: air supply pressure, thickness of the substrates and installing direction of the vortex bearing element. We find that during the process of transport...

Kinetic models are the most important tools for the prediction and evaluation of the flotation circuits performance. In order to determine the kinetic order and rate of flotation of a Gilsonite sample, flotation experiments were conducted using the combination of Gasoline-Pine Oil, and one test without any collector and frother. The pulp density was 10% and the experiments were carried out in b...

in this study, deinkability of old newspaper by conventional method and the effect of washing, flotation and combined washing/flotation processes were investigated on optical and superficial properties of the produced papers. the results from measuring of the optical and superficial properties indicated that using chemical treatment time of 20 minute and one stage washing resulted the papers wi...

This study developed a coagulation-flotation process for microalgae Chlorella sp. XJ-445 harvesting, which was composed of algal surface modification by combined use of Al3+ and cetyltrimethylammonium bromide (CTAB) and followed dispersed bubble flotation. Dissolved organic matter (DOM) in the medium was firstly characterized and mainly consisted of hydrophilic low molecular weight molecules. T...

Industrial wastewater contains a lot of pollutants and therefore needs special treatment processes. The treatment process may contain mechanical, biological, chemical, physical and physiochemical such as Coagulation – Flocculation process. The goal of this experimental work was to investigate the effects of coagulationflocculation and dissolved air flotation as a hybrid process of industrial wa...

This paper presents a novel simulation concept for operator training in the field of mineral processing. The simulations are carried out with a dynamic process simulator HSC Sim ® of HSC Chemistry ® developed by Outotec Research Oy. The simulator is fitted to mimic an existing copper flotation circuit as accurately as possible by using metallurgical models and then integrated into a larger simu...

The froth flotation technique can be considered one of the most efficient methods for separation minerals. Prior to utilizing any physicochemical method, size mined ore must decreased facilitate release valuable materials. This practice, along with increased exploitation ores that carry fine mineral particles caused production and ultrafine which are difficult recover classical enrichment metho...
