Sep 17, 2015 On the below Chart, selective flotation (separation) is obtained from the green line (1% mass) to the red line (4.5% mass). After 4.5% mass, you get mass pull, just mass. No selectivity, no concentration. You could float all day and yes get more mass. You could float off the whole tailings if you have enough time

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
Apr 15, 2005 Deinking selectivity (Z-factor): a new parameter to evaluate the performance of flotation deinking process 1. Introduction. Since its introduction in the 1980s, flotation deinking has been adopted as a standard practice for... 2. Definitions. In chemical engineering science, the degree of any
The froth flotation is a separation method that is used for selective separation of hydrophobic minerals from hydrophilic ones. It is one of the most important meth
Aug 18, 2016 Selectivity index and modified flotation rate constants of copper and iron based on kinetic model of Agar were evaluated to rougher flotation of the
the flotation selectivity used in mineral flotation. It is a mea- sure of the effectiveness of a deinking process to selectively remove ink. The selectivity used in mineral flotation is to measure the selective separation of various grades of miner- als. The goal of the present study was to develop a balanced
This invention provides a process for improved separation of mono/multi-metallic sulphide minerals from significant amounts of iron sulphides, mainly pyrrhotite and/or their finely divided process middlings. The process comprises subjecting such material to a conditioning stage with at least one water-soluble sulphur-containing inorganic compound as a prerequisite step for further conditioning
In effect, the objective of these processes is to maximise the flotation selectivity of one mineral with respect to the others present in the ore feeding the process. Small scale laboratory batch flotation tests have traditionally been used to assess the pulp mineral selectivity of the feed to a flotation process

A process for the selective froth-flotation of sulfidic, oxidic and salt-type minerals, whereby an ore is first wet ground to the flotation fineness to obtain a slurry and then the obtained slurry is prepared and froth-flotated. In addition to the collector agent a polysaccharide, lignosulfonate, quargum and/or a surface active additional

Froth flotation is a selective separation process, which is affected by many factors related to the floated mineral such as grade, degree of liberation, surface properties and many operating variables etc. (Cilek, 2004). Flotation is a complex process which involves the interactions of three phases (gas
Dec 20, 2018 Froth Flotation machine plays an indispensable role in the mineral beneficiation process, flotation is susceptible to a number of factors during the process, including grinding fineness, slurry concentration, pulp pH, pharmaceutical system, aeration and agitation, flotation time, water quality and other process factors. The factors that affect
Selectivity in a flotation process is typically achieved on the basis of differences in surface hydrophobicity. However, selectivity is based on all recovery mechanisms as well as hydrodynamic conditions. Selectivity can be enhanced by: Maximizing flotation rate differences. Eliminating or Minimizing Entrainment. Selective Detachment
The selectivity in flotation columns involving the separation of particles of varying degrees of floatability is based on differential flotation rates in the collection zone, reflux action between the froth and collection zones, and differential detachment rates in the froth zone. Using well known theoretical models describing the separation process and experimental data, froth zone and
Jan 30, 2015 For example, in poly-metal ores such as Pb-Zn-Cu, floatation allows separate extraction of Pb, Cu and Zn. The process of separation of mineral includes three important mechanisms : 1. TRUE FLOTATION, i.e., selective attachment to air bubbles. 2. ENTRAINMENT in the water which passes through the froth. 3
As such, entrainment greatly deteriorates the selectivity of the froth flotation process [17,18]. The amount of hydrophilic entrainment associated with a flotation unit is believed to be affected by the amount of water carried in the froth [19,20,21,22,23,24]
