The Effect of Superficial Feed Velocity on the Column Flotation Recovery in Comparison with the Conventional Flotation Cells [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1997
Flotation is the most important process for concentrating mineral ores. This process may occur in any vessel such as column flotation, which has been used widely during the last decade and the conventional flotation cells.

Removal of Nickel and Cadmium Ions from Wastewater by Sorptive Flotation: Single and Binary systems

open access: yesJournal of Engineering, 2023
The removal of heavy metal ions from wastewater by sorptive flotation using Amberlite IR120 as a resin, and flotation column, was investigated. A combined two-stage process is proposed as an alternative of the heavy metals removal from aqueous solutions.

CFD model simulation of bubble surface area flux in flotation column reactor in presence of minerals

open access: yesInternational Journal of Mining Science and Technology, 2018
Bubble surface area flux (Sb) is one of the main design parameter in flotation column that typically employed to describe the gas dispersion properties, and it has a strong correlation with the flotation rate constant.

Fine coal beneficiation by pilot column flotation [PDF]

open access: yesJournal of Mining and Metallurgy. Section A: Mining, 2018
Beneficiation of coal fines with high ash content was attempted in an operating coal preparation plant by retrofitting a 0.5 m diameter pilot plant scale flotation column in the circuit. The collector and frother dosage were optimized as 0.680 kg/t and 0.

The bio-column flotation of coal for desulphurization and comparison with conventional and column flotation [PDF]

open access: yes, 1994
Coal desulfurization of a type of British coal, containing 3% total sulfur, by bio-oxidation of surfaces of pyrite particles in the coal during column flotation was investigated. Growth of bacteria occurred in Tuovinen&Kelly Medium (1973).

Extracellular matrix remodeling and immune reprogramming drive residual tumor progression of liver cancer after incomplete microwave ablation

open access: yesMolecular Oncology, EarlyView.
Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...
