· float cells. Cleaner concentrate was collected as shown in Figure 4, and tailings were pumped to a thickener tank, and finally dewatered in a supersack. Because the material had somewhat oxidized in the time between the first and second flotation, a different promoter was required to promote the flotation reaction (Aero® 7512 Promoter).

· flotation, under different collector dosages (or frother dosages). At a low collector dosage (<3000 g/Mg), the yield of the concentrate the yields of the flotation column was much higher than that of the mechanical flotation cell. This is due to the increase in the collision probability between fine particles
The MAC flotation cell is mainly used in the flotation section of waste paper deinking pulping, for removal of hydrophobic impurities such as filler, ash, ink particles, etc. It can increase pulp whiteness and meet the requirements of final paper appearance quality. Table 11.11 shows the features of MAC flotation cell.

· the involvement of flotation size bubbles, typically in the range of 600 μm to 2 mm, is still required (Tao, 2005). Therefore it is suggested that the pico-bubbles be introduced into flotation cells to complement rather than replace flotation size bubbles (Nesset et al., 2006). Research has shown that

column flotation, covering pilot testing and scale-up, circuit design of selected applications, and instrumentation and control. We begin with a description of the key features and concepts of column flotation. KEY FEATURES AND CONCEPTS . A schematic of a flotation column is shown in Figure 1. Industrial flotation columns are 6-14 m
Jameson Cell has 100% accurate scale-up reliability and is the real-word specification in any and all duties within a flotation circuit: rougher and scavenger duty. cleaner and cleaner scavenger duty. In fact, a single Jameson Cell has successfully replaced a traditional circuit of cells; and unlike other competing cells, it has no moving parts.
· All flotation tests were conducted at room temperature with a 1000 ml Denver laboratory flotation machine. Pulp density was adjusted to about 30% solid by weight. The pulp was conditioned in the flotation cell for 10 minutes for each test before air was introduced. Flotation (concentrate collecting) time was set at 4 minutes for each test.
The flotation tests yielded a concentrate grade of 3.93%TCu and concentrate recovery of 64.36% with sodium su lphide consumption at 200 g/t, sodium isobu tyl xanthate at 150 g/t, ethylen ediamine
Flotation Cell. Flotation cell is widely used for separating non-ferrous metal, black metal, noble metal, non-metal mineral, raw body and materials of chemical industry, which are subject to coarse separation, swept separation, fine separation and flotation, so …
· Then the concentrate is discharged from the flotation cell through scrapers or self-flow. Non-target minerals are retained in the slurry area and discharged from the tank.
