Effect of different reagent regime on the kinetic model and recovery in gilsonite flotation

Journal of Materials Research and Technology, 2019
Gilsonite is a natural fossil resource, similar to an oil asphalt high in asphaltenes. To determine the effect of reagent regime on the kinetic order and rate of flotation for a gilsonite sample, experiments were carried out in both rougher and cleaner ...

Flotation performance analysis on coal washery rejects

Energy Geoscience, 2021
The coal washery rejects cause major environmental problems in various parts of the globe. Nearly 1 Mt of coal rejects discarded as waste, is accumulated per annum in India, during washing or cleaning of raw coal.

Late Quaternary lake filling and drying in northern Australia's largest freshwater lake

Journal of Quaternary Science, EarlyView.
ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...

Influence of operating parameters on nanobubble-assisted flotation of graphite

Journal of Materials Research and Technology, 2022
Although many studies have focused on processing of lithium-ion batteries (LiBs), there is a considerable lack of information concerning the application of nanobubbles (NBs) in their floatabilities.

Dynamic property evaluation of frother [PDF]

, 2019
Fourteen solvents were evaluated through frothing test and laboratory flotation batch tests. A new frothing parameter, initial dynamic froth index (IDFI), is proposed to compare the frothability of solvent.

Feeding Practices and Welfare of Zoo‐Housed Giraffes (Giraffa camelopardalis) on a Global Scale

Zoo Biology, EarlyView.
We collected feeding and stereotypy information on 702 giraffes from 146 zoos from all over the world. Less appropriate diets were linked to more oral stereotypies. ABSTRACT Since giraffe feeding practices have only been reported for European and US facilities, this study aimed to achieve a comprehensive overview of the current giraffe feeding ...

Surface roughness in bubble attachment and flotation of highly hydrophobic solids in presence of frother – experiment and simulations [PDF]

, 2017
In this paper, the kinetic of the three-phase contact (TPC) formation and the flotation recovery of highly hydrophobic solids with different surface roughness were studied in pure water and aqueous solutions of n-octanol.

Valorizing Erasure: Imperial Knowledge Production in Anglo‐American Coverage of Chad's ‘Toyota War’

The British Journal of Sociology, EarlyView.
ABSTRACT How does imperial knowledge production operate when Western media coverage of a Global South subject is predominantly admiring instead of hostile? This article addresses that question through critical discourse analysis of sixty‐three Anglo‐American news articles covering the Chad‐Libya conflict of the 1980s, the ‘Toyota War’.

The Impact of Vertical Fiscal Imbalance on Gambling Policies in New South Wales, Australia: The Rise of the Poker Machine

Australian Journal of Politics &History, EarlyView.
ABSTRACT This study traces how gambling in Australia changed from a simple form of leisure, enjoyed by all social classes in colonial times, to a billion‐dollar industry driven by political and economic imperatives. Using a case study, it links vertical fiscal imbalance (VFI), caused by changes to the state‐federal taxation structure, to the ...

Some Frothing Characteristics of Flotation Frothers

FLOTATION, 1968
Water content, overflowing fluidity and weight of entrained gangue particles in froths containing gangue were investigated, using MIBC, Yarmour F Pine oil, Dow Froth 250 as frothers in 500g Kyodaitype flotation test machine. Dry-grouned quartz and marble were used as gangue in the quantity of 100g/2.1-2.2l of solution.
