the effect of concentration of copper on froth flotation

2000-5-1 · The majority of research into copper activation during flotation has concentrated on individual sulphide minerals like those in the iron sulphide group (Chang et al., 1954; O'Connor et al., 1988; Bradshaw and O'Connor, 1994), galena (Popov and Vucinic, 1990) and sphalerite (Girczys and Laskowski, 1985) and not on the possible effect of copper

2019-12-26 · As a result, the residence time of the pulp in the flotation machine will be extended or shortened. Therefore, the pulp concentration indirectly affects the ore recovery rate and concentrate grade by affecting the froth flotation time. 2. Indirectly affect froth flotation by affecting the volume concentration of the froth flotation agent

2016-10-1 · Copper recovery increased from 85% to 90%, 94% and 93% at the end of flotation, in the presence of DP-1777, DP-1775 and DP-1778, respectively. DP-1775 and DP-1778 had a better effect on copper recovery than DP-1777. The presence of biopolymers also led to an increase in flotation rate, seen as the higher copper recoveries in the first concentrate

effect of sodium oleate concentration variations on froth

Each type of a manganese deposit is a problem by itself in the matter of selection of a proper method of concentration, depending on the manganese minerals and their gangue constituents. Hence, this work studied the effect of sodium oleate concentration variation on the froth flotation of manganese ore obtained from Madaka, Niger State, Nigeria

2019-9-20 · In froth flotation process, the pH value of the pulp needs to be paid close attention to at all times. The pH value needs to be measured with a test paper every once in a while to ensure that the pH value remains at a stable value. And the pulp concentration and liquid level need to be stable, ensure scraping, foam to scrape out the full plate

2018-11-27 · It is widely accepted that particles stabilise flotation froths and that stable froths result in improved flotation performance. Predicting the effect of particle addition on froth stability is, however, challenging. Dynamic surface tension measurement using maximum bubble pressure presents an attractive technique to investigate the effect of surfactant and particles at the air-water interface
