There is a lack of electrochemical studies of oxidized gold ores since the majority of previous studies were conducted with sulphidic gold ores. In this study, the influence of agitation and iron oxide minerals, i.e. magnetite, hematite, and maghemite on gold leaching was investigated by means of galvanic and passivation phenomena. Cyclic voltammetry studies of Roasted Gold Ore (RGO) in de-aerated electrolyte have shown one oxidation and one reduction reaction while three oxidation and one reduction peaks were observed with gold electrode. Galvanic coupling results by Zero Resistance Ammeter (ZRA) mode indicated that magnetite showed a negative effect on gold …

The interaction between gasses, liquids, and solids plays a critical role in many processes, such as coating, granulation and the blast furnace process. In this paper we present a comprehensive numerical model for three phase flow including droplets, particles and gas. By means of a coupled Computational Fluid Dynamics (CFD) - Discrete Element Method (DEM) approach the physical core phenomena are pictured at a detailed level. Sub-models for droplet deformation, breakup and coalescence as well as droplet-particle and wet particle-particle interaction are applied. The feasibility of this model approach is demonstrated by its application to a rotating drum coater. The …

A Novel Material Used In Automotive Industry: Compacted Graphite Iron, Ajit Behera
Ajit Behera
In recent decades, materials have been a key to increase the performance of automotive parts which leads to development of new materials. The main objective is to achieve increase in quantity and quality of automotive parts produced with optimum performance during their life cycle. Cast iron has remained a competitive material due, in part, to its low production cost. In fact, among the cast iron group, one of the alternatives is lightweight alloys, that is, compacted graphite iron (CGI). Nowadays, it is accepted that CGI can effectively reduce the total weight of an automobile by virtue of its high strength- …
