Modeling A Technology Of Ecological Gold Extraction, Case Of A Separating Cyclone

Abstract

Through the major mining operators, mining resources are one of the driving factors for Madagascar. However, for gold small panners, the volatility of their daily income has an influence on their source of income, possibly on their standard of living and by rebound to the development of their respective localities. The methodology adopted is both quantitative and qualitative. Its eventual realization requires a priori passing through the chronological order of the following activities: bibliographic research and webography, field trips to collect data and see firsthand the reality of gold mining technology.  The result of this work has led to the development of the new artisanal gold mining technology: the cyclone separator. This article consists of modeling and simulating the geometry and the principle of operation of the separator. The operation is assessed through two main performance indicators, separating efficiency and speed. The geometry, the separation regime and the properties of minerals are the three groups of parameters that affect the performance of the separation device. The variable fluid separation within the separating cyclone was studied by numerical simulation with ANSYS.
