The recovery of gold from flotation concentrates

dissolved gold with activated charcoal and the recovery of the charcoal by flotation. The flotation concentrates so produced consist mainly of charcoal with the precipi­ tated or adsorbed gold and ore constituents in varying amounts floated with the charcoal. If such processes prove commercially feasible the gold must be economically recov­

What can be done when in gold flotation concentrates I

Aeration after transfering the pulp to the cell can be lead to better flotation results. Gold and copper should be in the concentrate if they are completly separated. Cite

Flotation of Gold and Gold-Bearing Ores ResearchGate

This paper aims at investigating the gold leaching behaviour of refractory, bio-oxidized flotation gold concentrates, before and after high intensity milling, for enhancing gold extraction.

Gold recovery from refractory gold concentrates by

The flotation concentrate of gold used in this work was from Shuiyindong gold mine of Guizhou Zijin Mining Co., Ltd in Guizhou province of China. The concentrate of gold was obtained by two roughing-two cleaning-four scavenging operation in the dressing plant. The results of chemical analysis of the flotation concentrate of gold are shown in

Gold Processing,Extraction,Smelting Plant Design

The flotation concentrates can be sold to the smelting factory based on normal trade or processing agreement. The flotation concentrates go to cyanide process or calcination process (if there is arsenic together with the concentrate) and further process to get pure gold in the smelting factory.

Separation efficiency improvement of a low grade copper

The copper flotation circuits upgrade copper content by a factor of 80-160 times from feed to a saleable copper concentrate containing approximately 50% of the contained gold in feed (remaining gold is recovered both as a gravity product within the primary grinding circuit and also via leaching of a gold-containing pyrite concentrate).

1 Froth Flotation Fundamental Principles

1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air

Size dependent gold deportment in the products of copper

before flotation to produce a pyrite concentrate. This was performed to improve discrimination and precision in the subsequent gold deportment analysis. Concentrates from the pyrite scavenger stage were collected after 2 and 6 minutes. The pyrite scavenger concentrates and tailing were then filtered and stored prior to analysis. Gold deportment

The role of sodium sulfide in the flotation of pyrite

Apr 01, 2018· In copper flotation, gold is floated with copper minerals, while pyrite is depressed in order to produce a saleable copper-gold concentrate. Then, the depressed pyrite is activated and floated to recover the remaining gold associated with pyrite (Zheng and Manton, 2010).
