abstract one of the most important sources of drinking and agricultural water needs is rivers. one of the oldest methods of getting water from rivers that still has the greatest use is the gravity intake. in this type of intake, due to the disproportionate velocity at the upstream and downstream mouth of intake, occur flow separation and following sedimentation at the upstream mouth. in this st...

Application of gravity and magnetic separation methods to upgrade low grade Manganese ores from Venaj Mine has been reported elsewhere. This paper discusses the results of flotation tests, as well as combination of flotation and magnetic method to concentrate fine particles (less than 150 microns) of manganese ore. Results obtained from various direct and reverse flotation tests, using differen...

Abstract: point of view. In this study, a shaking-table was used for concentrating a manganese ore sample from the Ghasem Abadarea in Kerman, Iran. Experiments were designed by using LThe influence of each variable and their interactions on the operation of the device was studied. The variables underinvestigation were: table slope, table frequency, water flowrate, feed rate, and particle size. ...

Over the last three decades, in order to reduce environmental issues of processing fine mineral separation methods such as flotation while decreasing capital cost, gravity has become significantly important. Falcon concentrators enhanced separators have been developed for sharper beneficiation finely disseminated ores based on their specific differences. employed centrifugal force, which is man...

Biodegradable plastics should be appropriately managed independently of general during and after use. To establish an effective recycling process for biodegradable plastics, the present study investigates evaluates applicability gravity separation. Experimental results indicate that a laboratory specific-gravity separator achieves recovery ratio >98% at purity >99.9% light-density as float prod...

Liposomes are used widely as drug delivery systems in different forms including nanosuspensions, osmotic pumps, infusion pumps, and IV injections. Some of these systems (e.g. infusion or osmotic pumps) might stay stagnant for a long time during or before administration, and therefore, might face phase separation. In spite of these, there are no data available about the behavior of liposomal sys...

Gravity, magnetic and electrostatic separation methods allowed to obtain different titanium oxide concentrates (ilmenite, leucoxene, rutile) varieties of zircon (premium zircon, standard medium grade standard) from Senegal’s heavy mineral sands. During mining separation, monazite, which is a paramagnetic mineral, was found in non-negligible concentration 0.57 wt% on average the also contains 37...

Separation of solids from liquid swine manure and subsequent thermochemical conversion (TCC) of the solids fraction into oil is one way of reducing the waste strength and odor emission. Such processing also provides a potential means of producing renewable energy from animal wastes. Gravity settling and mechanical separation techniques, by means of a centrifuge and belt press, were used to remo...
