Enhancing flotation separation of chalcopyrite and galena

Mar 30, 2020· 2.2. Method2.2.1. Flotation tests. Flotation tests were performed in an XFG-type flotation machine. During each test, 10.0 g of single or mixed (chalcopyrite–galena mixture ratio of 1:1) minerals were placed in a 150-mL flotation cell and mixed with 150-mL deionized water. The pH of the pulp was adjusted to a specified value using HCl and NaOH.

Oct 01, 2020· 2.2. Micro-flotation tests. The micro-flotation tests were performed on a XFG5-35 flotation machine. 2.0 g galena or molybdenite were pre-cleaned in an ultrasonic bath for 3 min. Later, the samples were transferred into a 40-mL flotation cell, and the pH was adjusted to a desired value.

Jan 01, 2021· The role of hydrogen peroxide (H 2 O 2) and hydroxyethyl cellulose (HEC) in the flotation separation of chalcopyrite and galena has been investigated and the reason why H 2 O 2 can enhance the depression effect of HEC has been explained. The results show that either H 2 O 2 or HEC can depress galena selectively, but the reagent concentration needed is large. A small amount of HEC

Investigations on the depressant effect of sodium alginate

Jan 01, 2021· The micro-flotation tests on the galena samples were conducted on an XFG flotation machine with a 40 mL plexiglass cell (Chen et al., 2019). The − 74 + 38 μm size fractions of the galena samples were prepared by wet-grinding the stored samples with a ceramic ball mill and were used for the micro-flotation tests.

Flotation separation of chalcopyrite from galena by

3.1.2 Flotation of chalcopyrite and galena with HA as depressant The effects of HA on the flotation recoveries of chalcopyrite and galena at pH 6.5 were determined (see Fig. 4). The results indicate that with the increase of HA concentration from 0 to 75 mg/L, the floatabilities of the both minerals remained relatively constant, while as the

The flotation experiments were carried out in an XFG-type flotation machine [19,35 38] at a spindle speed of 1850 rpm. In each flotation experiment, a single-mineral sample (2.00 g) or mixed-mineral sample (1.00 g pyrite plus 1.00 g galena) was added to the flotat ion cell (with 40 mL DI water) to obtain the mineral suspension.
