Dec 20, 2018· When flotation of gold and silver sulfide ores, the general xanthate dosage is 50-150 g/t. Usually, the dosage increases with the increase of metal grade and oxidation degree. Experience shows that the use of mixed collectors is better than that of single collectors, which not only improves the selectivity of the flotation separation process

May 08, 2013· This paper presents the results of the effect of different collector combinations on gold and silver recoveries from lead and zinc ores by flotation. Best results were obtained on the use of Aero 208 + Aerophine 3418 A as collectors at the dosages of 350 + 350 g/t and 1000 g/t Na 2 SiO 3 as a depressant at pH 4.5 where particle size was below
Simply said; a Flotation Collectors is a chemical used to make the surface of minerals, which is metallic, hydrophobic or in layman’s term ‘afraid of water’ or ‘water hating’ as others like to say. This chemical used will behaved, in a way, as a wax would when you applied it to your car. After wax (or hydrophobic agent) is adhered to the surface, that surface with see water pearl
3.1.2. Effect of Collector Dosage Flotation behavior of copper and nickel from mine tailing was investigated un-der varying concentrations of PAX ranging from 0 g/t to 200 g/t when other flo-tation parameters were fixed at 200 g/t of MIBC concentration, 50 g/t of pulp density, slurry pH of 5400 rpm of stirring speed and 6 minutes flotation time. As
Florrea can supply 5050 flotation collector ,which is an excellent replacement to Aerophine Aero 3418A promoter . 5050 has much more benefit than Aerophine Increased recovery of precious metals including silver and gold Better recovery for zinc minerals Florrea 5050 can substantially reduce the dosage of depressants such as zinc sulphate and cyanide etc. Higher recoveries and selectivity in

Nov 01, 2019· At Silver Queen mine (Canada) a combined lime-starch-SO 2 conditioning scheme is used for copper flotation from the Pb/Zn sulphides (Bulatovic, 2007b). In the process, lime (1200 g/t) and starch (200 g/t) are used first, at pH 10.5–11.2, after which the pH is reduced to 5.5 with SO 2 (200 g/t) and the copper sulphide floated.
The flotation performance of the collectors was evaluated using a laboratory mechanical flotation cell at different process parameters such as pH, Collector dosage, diesel dosage and flotation time and using two collectors: a commercial plant collector (I) and a refined tall oil fatty acid (II).
After selecting the floatation principle, Xinhai mine research institute will select the flotation reagent schemes for different floatation cycles one by one, which is required to refer to the practical experience of similar mineral processing plants, and analyze the ore properties, possible flotation schemes, then select the collectors
batch flotation procedure was used in this investigation and changes in electrochemical potential were monitored as collector was added to the flotation cell. It is hypothesised that the benefits of collector mixtures are only evident at low dosages, thus, dosages were carefully controlled. The study aimed to

Reagent dosage: In the flotation process, the pulp must maintain a certain concentration of agents to obtain good flotation technology indicators. When the pulp is relatively thick, the concentration of reagents in the liquid phase increases, and the dosage of reagents for each ton of ore will be reduced.
Froth flotation is a good example of an engineering “system”, in that the various important parameters are highly inter-related, as shown in Figure 1. It is therefore important to take all of Chemistry Components Collectors Frothers Activators Depressants pH Equipment Components Cell Design Agitation Air Flow Cell Bank Configuration

The flotation collectors used in sphalerite flotation tend to be less powerful because sphalerite at this stage typically readily floats and using a more aggressive collector can float more non-sphalerite minerals. Optimum lead concentrate metallurgy and recoveries are usually achieved using a combination of a xanthate and dithiophosphates.
