Response surface methodology (RSM) is one of the most effective tools for optimizing processes, and it has been used in conjunction with Analysis Variance (ANOVA) test to establish effect input factors on output factors. However, when this mineral flotation, its polynomial model usually performs poorly. An alternative use artificial neural networks (ANNs) such situations. Within context, ANOVA ...

This paper studies the effect of type and concentration selected frothers, gas flowrate, pore size porous frit on bubble sizes (Sauter mean diameter, SMD) bubbling flow produced in a micro-flotation cell, determination distribution (BSD) presence frothers. The commercial frothers polypropylene glycols (PPG 200, 400, 600), tri propylene glycol (BTPG), triethylene (BTEG), dipropylene (BDPG), Meth...

tabas mines in iran have coal sources which are suitable for use in metallurgy industries as coking coal. but the high sulfur content of this coal imposes severe limitations on its utilization as the sulfur oxide gases evolved from the combustion of high sulfur coals result in acid rains and corrosion of equipments. in this work, attempts have been made to reduce sulfur from high sulfur coal of...

This paper reports physical and physicochemical routes for the recycling of gold, silver, copper from waste printed circuit boards (WPCBs). The results optical micrographs indicated that metals matrix are substantially separated slot after comminution process. effects various operational factors, including gravitational force fluidization water, centrifugal separators on separation performance ...

In flotation, the froth structure and froth stability are known to play a significant role in determining the mineral concentrate grade and recovery. Froth stability is not only depending on the type and amount of the frother used, but also on the amount and nature of the suspended particles. Furthermore, there are other parameters such as quality of water which are not yet fully understood. In...

Abstract Gilsonite has a wide variety of applications in the industry, including manufacture electrodes, paints and resins, as well production asphalt roof-waterproofing material. ash is determining parameter for its application some industries (e.g., gilsonite with content < 5% used an additive drilling fluids, resins). Due to shortage high grade (low ash) reserves, aim this study develop p...
