a wet process for the beneficiation of a fly ash by-product has the following steps: a) forming a slurry mixture of a fly ash material and a liquid; b) gravitationally separating and collecting a first material fraction of the fly ash having a density less than the liquid by skimming off floating slurry material; c) separating a first magnetic fraction from the slurry by subjecting the slurry to a magnetic field of from
the ph was gradually raised to 2.05 to form a suspension of the insol- ubie titanium-containing material that simulta- neously adsorbed the /?/!o^ocuc'(m.s g!n-1 magnetite biosorbent. after short mixing (5 min), the suspension was subjected to magnetic separation at 400 g in a davis tube magnetic separator (edt model, eriez magnetics, erie.
generally, the present invention involves the steps of: a) forming a slurry mixture of a fly ash material and a liquid; b) gravitationally separating and collecting a first material fraction of the fly ash having a density less than the liquid by skimming off floating slurry material; c) separating a first magnetic fraction from the slurry by subjecting the slurry to a magnetic field of from about 300 gauss
future designs of magnetic drum separators should consider (1) reducing the burden depth at the separator inlet so that with a smaller-strength magnet (a) refuse would not be carried along with metallic materials to pollute the metal stream and (b) materials would not be so magnetized that they would adhere permanently to the drum surface, (2) establishing an optimum drum rotational speed such that
these waste materials include mining waste, construction and demolition waste, wood sawdust, cotton waste, limestone powder, paper production residues, petroleum effluent treatment plant sludge, kraft pulp production residue, cigarette butts, waste tea, rice husk ash, crumb rubber, cement kiln dust, and coal fly ash (zhang 2013; bennet et al., 2013; saeed and zhang, 2012).
the tailings (non-float) product is clean fly ash. it is pumped to a thickener and dried. after the rougher flotation, the carbon product recovered in the float fraction is cleaned further in a series of flotation cells, serving as cleaning stages. the process typically yields clean fly ash with 0.6 % loi (loss on ignition).

a literature study on the distribution of metals in incineration ash showed that most metals (85% on average) end up in the bottom ashes and a minimum of 10-15% is lost in the flue gases or fly
the residual amount of aluminium concentrates in the fly ash or in the fine fraction of the bottom ash and its recovery is virtually impossible using the current eddy current separation technology.
