Optimisation of gold recovery by selective gold flotation

Copper sulphides are selectively floated from pyrite ores at high pH's in excess of 11. It is less clear how the free gold behaves under these conditions. In addition, for extra gold recovery, further collectors are added, such as the monothiophosphates, which are known to

Optimisation of gold recovery by selective gold flotation

Feb 01, 2001 Optimisation of gold recovery by selective gold flotation 231 S-701 was shown to give optimal recovery in an acid float, at an approximate pH of 4.5. S-701 could be used to recover the majority of the pyrite associated gold and then with either xanthate or one of the other new collectors (e.g. F-100) the copper could be recovered at the basic pH.

OPTIMISATION OF THE SELECTIVE FLOTATION OF GALENA

the selective flotation of the Cu-Pb-Zn sulphide ore from the Rosh Pinah Mine (Namibia). The objectives of this study are outlined in Chapter 1. The main objective is to optimize the reagent suite in the lead flotation circuit, thus improving the flotation selectivity between galena and sphalerite. The optimization of the reagent

Selective Flotation Mineral Processing & Metallurgy

Sep 17, 2015 On the below Chart, selective flotation (separation) is obtained from the green line (1% mass) to the red line (4.5% mass). After >4.5% mass, you get mass pull, just mass. No selectivity, no concentration. You could float all day and yes get more mass. You could float off the whole tailings if you have enough time.

Jan 21, 2022 Flotation is an effective technique that used to achieve the separation of bastnaesite from its associated gangue minerals. However, the effectiveness of the flotation is greatly impacted owing to the presence of dolomite as a result of collector's non selective adsorbing behavior towards the two minerals [1], [4].
