Investigation on flotation separation of bastnaesite from ...

In order to improve the flotation separation efficiency of bastnaesite from barite and calcite, a novel collector, octylamino-bis- butanohydroxamic acid OBHA , with large molecular structure and two functional groups was synthesized based on the molecular design of flotation reagents theory.

Flotation Reagent - an overview ScienceDirect Topics

Flotation Reagent. Flotation reagents have two important structural features: a functional group consisting of donor atoms or ligands, and a substituent group, which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers, or hydrophilic in the case of modifiers except for inorganic modifiers, which comprise mainly inorganic bases and metal ions .

Flotation Reagent - an overview ScienceDirect Topics

S. Chander, D.R. Nagaraj, in Encyclopedia of Separation Science, 2007. Reagent Selection and Optimization. In the 1920s and 1930s the number of commercially used flotation reagents was relatively small, and reagent selection for a given appli ion was relatively straightforward. As the number and diversity of commercially available flotation ...

Gas-assisted low-field magnetic separation for efficient ...

This makes scaleup of magnetic separation process difficult. Second, low field and low gradient means small magnetic force acting on magnetic nanoparticles, leading to slow magnetic separation efficiency. The capture of particles by rising bubbles in froth flotation has been widely applied for mineral ores , coal , plastics , and so on. The ...

An efficient separation for metal-ions from wastewater by ion ...

For the subsequent flotation process, the precipitate particles/flocs with large size and small density may mean higher floatability and efficient separation index. 3.2. Structure evolution of metal-reagent precipitate particles/flocs. Reagent is a key factor influencing the structure of metal-reagent precipitates Harif and Adin, 2011 .

Magnetic Reagents - Metallurgist and Mineral Processing Engineer

The magnetic reagents can be used to enhance direct separations, much in the same manner as flotation reagents. Fine tuning the magnetic reagent to attach to a certain mineral in the slurry and then performing a magnetic separation to remove that mineral will be possible. Coal Cleaning with Magnetic Reagent. Coal is an important energy resource.

Separation Efficiency - Metallurgist and Mineral Processing ...

The technical excellence of separation achieved in a mineral concentration process, or any other process where two constituents of any kind are physically separated from each other, is expressed uniquely and quantitatively by the Separation Efficiency: Es = R – Rg where R is the percentage of the valuable constituent and Rg the percentage of the waste appearing in the concentrate. The ...

1 Froth Flotation – Fundamental Principles

After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: a Ratio of concentration b % Metal Recovery c % Metal Loss d % Weight Recovery, or % Yield e Enrichment Ratio Table 1: Grade/recovery performance of a hypothetical copper ore flotation process.
