The selective flotation of arsenopyrite from pyrite B. Tapley D. Yan * WA School of Mines Curtin University LB 22 Kalgoorlie WA 6433 Australia Received 8 May 2003 accepted 7 July 2003 Abstract Flotation tests were conducted to compare the arsenopyrite depressing effect of MAA with pH control potassium permanganate and preaeration.

Selective flotation of chalcopyrite from pyrite using

In a bid to achieve the separation of chalcopyrite from pyrite flotation has been employed. Pyrite is easily activated due to the galvanic interactions and the existence of copper ions dissolved during grinding and flotation (Mu et al. 2018 Peng and Grano 2010 Qin et al. 2015). Therefore the separation of chalcopyrite from pyrite has always been a challenge in mineral

Investigating the selectivity of a xanthate derivative for

Incorporation of the hydroxyethyl group was observed to increase the molecular properties of SIBX by increasing the number of active sites arrangement density selectivity and hydrophobicity thereby improving its flotation performance. Chalcopyrite was separated from pyrite using 4 × 105 mol·L1 HEIBX at pH 8.0.

Arsenopyrite an overview ScienceDirect Topics

Chitosan a linearpolysaccharide composed of randomly linked dglucosamine and Nacetyldglucosamine has been shown to be a selective depressant in the flotation of pyritegalena mixtures (Huang et al. 2013). The results indicated that chitosan preferentially adsorbed on pyrite and galena was floated from the pyritegalena mixtures.

Selective separation of pyrite and chalcopyrite by

Selective separation of pyrite from other associated ferrous sulphides at acidic and neutral pH has been a challenging problem. This paper discusses the utility of Acidithiobacillus ferrooxidans for the selective flotation of chalcopyrite from pyrite. Consequent to interaction with bacterial cells pyrite remained depressed even in the presence of potassium isopropyl xanthate

Selective flotation of chalcopyrite from pyrite

Flotation results showed that the selective flotation of pyrite from galena can be achieved under the preferred reagent scheme i.e. 400 g/t chitosan (10 kDa) 1600 g/t ethyl xanthate and 100 g

Investigating the selectivity of a xanthate derivative for

Incorporation of the hydroxyethyl group was observed to increase the molecular properties of SIBX by increasing the number of active sites arrangement density selectivity and hydrophobicity thereby improving its flotation performance. Chalcopyrite was separated from pyrite using 4 × 10 5 mol·L 1 HEIBX at pH 8.0.

Selective separation of chalcopyrite from pyrite with a

Thus this study offers a novel pyrite depressant polyglutamic acid (PGA) in the selective flotation of chalcopyrite with xanthate as a collector. The flotation and adsorption mechanism on chalcopyrite and pyrite were systematically studied using a series of flotation tests zeta potential measurements adsorption analysis infrared spectral (IR) analysis and Xray photoelectron spectroscopy

In this study the surface modification of arsenopyrite and pyrite with low temperature oxygen plasma was developed as an effective approach to improve the flotation separation efficiency of minerals. The microflotation experiments results indicated that plasma pretreatment can achieve selective flotation of arsenopyrite from pyrite. The XPS analysis results indicated that the oxidation
