Early work on gold particles with copper sulfate showed no improvement in recovery but an increased rate of flotation of gold (Leaver and Woolf, 1934). More recent laboratory testwork on a refractory gold ore has shown, however, that a 5% increase in free gold flotation recovery is achievable when adding copper sulfate (Teague et al., 1999b).
Gold losses during flotation often occur within the fines fraction, which has been an ongoing issue that has challenged the gold mining industry. Subsequently, operations will attempt to coarsen up the primary grind to reduce the fine gold (free gold or sulphide gold) generation, resulting from over grinding. Under-grinding can then to lead to gold losses in the coarse composite …
Our flotation cells are cell to cell type flotation machine which always combine several sets together as roughing stage, cleaning stages, or scavenging stages. Prominer can provide SF series self-priming flotation machine and XCF/KYF series pneumatic flotation cell which are mainstream products for the recovery and upgrading of sulfide ores.

This study investigates the flotation kinetics of individual platinum-group elements (PGEs) and gold, namely Pt, Pd, and 2E+Au (i.e., Pt+Pd+Au), in the context of Platreef ore flotation. Experimental tests were conducted on a Platreef ore feed using various dosages of depressants, frothers, and collectors under controlled agitation and pH ...
This study aims to develop an optimized primary flotation process for the treatment of gold-zinc-lead sulfide ore. Flotation tests were aimed at producing a bulk sulfide concentrate to …
APPLICATION OF FLOTATION TO GOLD ORE. A flotation plant is being erected at the Falcon mine, Rhodesia, to treat ore containing gold and copper. With the exception of the Mt. Morgan, the Etheridge, and the Great Fitzroy mines, Queensland, I have not heard of the flotation process being used successfully to treat ore containing an appreciable amount of gold.
Flotation machines constitute the basic equipment for useful minerals recovery from non-ferrous ores and other raw materials by flotation. They can operate also as individual flotation cells. Flotation Cells (Froth Flotation) were developed to separate and recover high-value Sulphide ores from low-grade ore bodies. The Flotation Cell is aerated to produce bubbles and agitated to …
This molybdenum flotation circuit, based on 250-500 tons per 24 hours is designed for low-grade molybdenum ore having high-grade streaks and with pyrite-quartz gangue.It is also basically sound for many other friable sulphide ores, such as antimony, silver and even some lead ores. The basic ideas stressed in this moly flotation flowsheet are the importance of simplicity …
In this study, a semi-industrial test was performed using the FCSMC and the mechanical flotation cell to determine the optimum separation conditions for Sanshandao low-grade gold ore. Flotation products were sized to calculate the size-wise grade distribution to investigate the characterization of the column and the cell in low-grade gold ore ...

The present paper describes the beneficiation of low-grade gold ore by flotation columns and the implications of improved metallurgy on subsequent cyanidation. 2. EXPERIMENTAL 2.1. The gold ore The mineralogical assay of gold ore revealed that the ore is semi-refractory containing both free and refractory gold approximately in the ratio of 80:20.
Here is a page about the invention of froth flotation as it appeared in a 1917 edition of the Popular Mechanics detailing how it works. Each cell has an impeller, this rotates and acts like a giant mixer. Its purpose is to keep the ore in suspension, provide a passage to allow the air access to mineral, and help distribute the air through the cell.
The Air Flow Number should lie within a narrow range for optimum flotation results for any one cell. Harris gives values for most commercial cells while Table 4 has more detailed data for Denver and Wemco cells based on more recent measurements for sizes up …
The combined FCSMC and cell flotation process for concentrating the Sanshandao low-grade gold ore showed promising results of producing a grade of 48.24 g/t gold with 96.13% recovery. This was mainly because the …

The largest flotation cells presently used in industrial flotation operation are 130, 160 and 250 m3. Figure 1 shows the main characteristics of a self-aerated cell, where the feed pulp circulates upwards through a draft tube by the rotor. Also, the air is self-aspirated from the upper part of the cell by the rotor. Figure 1. Large flotation cell
The performance of froth flotation cells is affected by changes in unit load, feed quality, flotation reagent dosages, and the cell operating parameters of pulp level and aeration rates. In order to assure that the flotation cells are operating at maximum efficiency, the flotation reagent dosages should be adjusted after every change in feed ...
