Copper arsenic flotation selectivity binq mining flotation tests were conducted to compare the arsenopyrite depressing eect of maa with pH control, potassium permanganate and pre-aeration. the recovery and selectivity were optimised by varying the collector and depressant concentration, pH and the eect of copper sulphate addition.

2014-11-1 Regrinding copper rougher concentrate improved the liberation of tetrahedrite/tennantite and improved copper/arsenic selectivity in laboratory cleaner flotation tests. Depression of arsenic in the copper cleaner circuit was mainly through reduction in flotation of composite particles containing the arsenic bearing mineral tennantite.

2017-10-1 The bulk rougher copper-arsenic concentrate then is reground in a closed circuit with a cyclone to become the feed to the arsenic rejection stage. • The separation flotation stage has two steps. The first step is arsenic flotation at −200 mV SHE, under nitrogen gas, to selectively depress the non-enargite copper minerals and float the enargite. It produces a high-arsenic low-copper concentrate

Technological process is very sensitive to so-called "selectivity" because loss of individual metals through selective concentrates is present. Copper minerals flotation cycle is especially sensitive to selectivity and sometimes ...

2013-6-21 Removal rates for arsenic, lead, and zinc were 48–61, 40–48, and 32–36 %, respectively. Flotation selectivity of Cu was greatly influenced by the contents of fine particles and organic matter of the sediments. The maximum flotation selectivity was obtained for the 53–125-μm size fraction.

The concentration of sulfhydryl collectors in the experiments was 10–4 mol/l. The acidity of the medium was created by H2SO4 and Ca(OH)2. The increased flotation activity of arsenic-containing DTF minerals is experimentally shown both individually and in mixture with ITC in a weakly acid medium (pH 4–6).

Abstract The separation of nickel arsenides and pentlandite was studied with batch flotation tests. Of the examined variables, aeration greatly improved the floatability of pentlandite and a high selectivity between pentlandite and nickel arsenides was obtained. A mechanism is proposed for the flotation selectivity improvement by aeration conditioning.

The flotation of the following metals was reviewed: copper, zinc, nickel, lead, iron, chromium, arsenic, gold, and others. The bubble generation method could be applied for typical dispersed-air flotation column, electroflotation, or dissolved-air flotation; the latter being the most appropriate established technique in water treatment.
