Selective flotation of sulphides from a gold mining operation

Samples of gold cleaner concentrate (approx. 150 kg) were collected in the flotation circuit in plant 2 of a gold mining company and stored in a nitrogen atmosphere. The samples received were homogenized and subdivided into subsamples of approximately 1 kg, for use in the analysis and liberation studies and the flotation studies. Chemical analysis of the gold

Separation efficiency improvement of a low grade copper

As can be seen in Table 1, the cleaner and recleaner banks are being operated with sufficient residence time to achieve flotation exhaustion of floatable minerals. In order to improve cleaning efficiency by further dilution of the cleaner and recleaner banks, additional flotation

Flotation of Gold and Gold-Bearing Ores ScienceDirect

1/1/2016· Gold hydrophobicity is enhanced by the addition of flotation collectors, and no flotation plant relies solely on the natural floatability of gold for its recovery. Naturally occurring or free (liberated) gold is optimally recovered in a flotation circuit at natural or near-natural pulp pH values and with the addition of small amounts of collector.

High Gold Recovery Results from Flotation Test Work at

7/13/2020· Flotation feed grades were 4.8 g/t and 2.3 g/t gold, respectively. Cleaner concentrate grades ranged from 105 g/t to 637 g/t gold. Flotation gold recoveries ranged from 77% to 80%. Overall recovery (gravity and flotation) for all laboratory tests presented in Table 1 exceeded 90% gold recovery.

AMIT 145: Lesson 5 Froth Flotation Mining Mill

Flotation Circuits. Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks. Rougher and scavenger banks are focused on recovery and thus provide maximum residence time. Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses.

Effect of pH on Copper Cleaner Flotation (after Regrind

In the study, batch cleaner tests were conducted to confirm the target regrind size and select the cleaner pH conditions. The objective of the high pH, collector-starved environment in the cleaners is: To liberate and reject attached silicates, Depress the previously-floated pyrite. If the floatability imparted on the pyrite in rougher flotation is not adequately depressed during regrinding
