Magnetic fraction of coal fly ash: its separation

Power plant fly ash, a high-volume waste product of pulverized coal combustion, contains a magnetic fraction which can be easily separated and has a high market potential. The fly ash from most of the U.S. bituminous coals contains 15 to 20 weight percent iron oxides, 50% or more of which can be recovered by dry magnetic separation as a high

Application of magnetic separation technology for the

Three-stage magnetic separation tests were performed on the size fractions coarser than 75 µm produced from the tailings (31.52% B 2 O 3) using a high-intensity permanent magnetic separator. Under the test conditions a colemanite concentrate with a B 2 O 3 content of 43.74% at 95.06% recovery was shown to be produced from the tailings.

Rock magnetic finger-printing of soil from a coal-fired

We present seasonal rock magnetic data for 48 surficial soil samples collected seasonally around a coal-fired thermal power plant on the southwest coast of India to demonstrate how fly ash from the power plant is transported both spatially and seasonally. Sampling was carried out during pre-monsoon (March), early-monsoon (June), monsoon (September) and post-monsoon (December) seasons.

Mechanisms of mechanochemical activation during

Oct 01, 2020· High-alumina coal fly ash (HAFA) is an important aluminum and silicon resource. In terms of its comprehensive utilization, how to efficiently separate aluminum and silicon must be resolved. In this work, a mechanochemical activation method in the desilication process is adopted and investigated.
