توده گرانیتوئیدی میشو متعلق به شمال غربی زون ایران مرکزی در شمال غرب ایران می باشد که به درون سنگ های دگرگون شده پرکامبرین نفوذ کرده است. بر اساس مطالعات پتروگرافی، این توده متشکل از چندین توده از سنگ های گرانیتی پان آفریکن می باشد که طیفی از دیوریت تا لوکوگرانیت را در بر می گیرد. ترکیبات حدواسط این مجموعه شامل آمفیبول گرانودیوریت، بیوتیت گرانیت و گرانیت دومیکایی می باشند. کوارتز ، پلاژیوکلاز ،...
This paper is one of a study that implements reverse flotation methods as an alternative beneficiation on bauxite processing. aimed at decrease silica content and increase alumina in so its qualified feed Bayer Process. The experiments were carried out 1375 mL cell tank. Dodecylamine (DDA) AERO 3000C used the collector, starch depressant, Dowfroth 1012 frother. overall conducted solid to soluti...
The molecular structure of the liquid–vapor interfaces aqueous solutions alkali metal halides and methyl isobutyl carbinol (MIBC, (CH3)2CHCH2COCH3) is determined by using dynamics simulations with polarizable force fields for first time. salts are chlorides, iodides, some which found in raw partially desalinated seawater increasingly used flotation operations regions affected severe prolonged d...
Fundamental studies of surface forces in foam films are carried out to explain the stability of foams and froths in froth flotation. The thin film pressure balance (TFPB) technique was used to study the surface forces between air bubbles in water from equilibrium film thickness and dynamic film thinning measurements. The results were compared with the disjoining pressure predicted from the Derj...
