Study on the mechanism and application of a novel collector-complexes in cassiterite flotation
TLDR
In this article, it is shown through flotation that BHA exhibits weak collecting capacity to cassiterite even in the case of using lead nitrate as the activator, but the superior floatation performances of lead(II)−BHA complexes is observed.About:

Selective adsorption of benzhydroxamic acid on fluorite rendering selective separation of fluorite/calcite
TL;DR: In this article, a benzhydroxamic acid (BHA) was used as a collector for the selective separation of fluorite from calcite without using any depressant, and the results from the zeta potential and X-ray photoelectron spectroscopy (XPS) indicated that the BHA easily chemisorbs onto the fluorite as compared to calcite.

Effect of Pb 2+ ions on ilmenite flotation and adsorption of benzohydroxamic acid as a collector
TL;DR: In this article, the effects of Pb2+ ions on ilmenite flotation and adsorption of benzohydroxamic acid (BHA) as a collector were investigated using microflotation tests, zeta potential measurements, adsorization analysis, Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopic (XPS).

Activation role of lead ions in benzohydroxamic acid flotation of oxide minerals: New perspective and new practice.
TL;DR: A new hypothetic activation model was proposed to explain the improved performance of soluble lead-BHA complex and the proposed model was verified by the flotation experiment and adsorption test results and can help enrich the activation theory of metal ions in anionic collector flotation of minerals.
Journal ArticleDOI
Improved flotation separation of cassiterite from calcite using a mixture of lead (II) ion/benzohydroxamic acid as collector and carboxymethyl cellulose as depressant
TL;DR: In this paper, a mixture of lead nitrate (LN) and benzohydroxamic acid (BHA) was used as collector and carboxymethyl cellulose (CMC) as depressant to separate cassiterite from calcite.

The adsorption of gases on plane surfaces of glass, mica and platinum.
TL;DR: In this article, the absorption index at the wave length of the band maximum was found to be proportional to the total concentration of metal at shorter wave lengths, however, deviations were observed, the absorption increasing more rapidly with concentration than Beers' law would demand.

T. Sreenivas,N. Padmanabhan +1 more
TL;DR: In this article, the surface chemistry and flotation of cassiterite in the presence of alkyl hydroxamic acid/salt surfactant has been investigated results of the adsorption isotherms, electrokinetic and infrared spectroscopy indicate that octyl hydroxamate adsorbs on cassite by both physical and specific forces.
