Bench-scale testing of the micronized magnetite process. Fifth quarterly technical progress report, July 1995--September 1995

PDF Version Also Available for Download.

Description

The major focus of the project, which is scheduled to occur through January 1996, will be to install and test a 500{number_sign}/hr. fine coal-cleaning circuit at DOE`s Process Research Facility (PRF), located at the Pittsburgh Energy Technology Center (PETC). The circuit will utilize an extremely fine, micron-sized magnetite media and small diameter cyclones to make efficient density separations on minus-28-Mesh coal. The main accomplishments of Custom Coals and the project subcontractors, during this period, included: continued purchasing small equipment and supplies for the circuit; procured a 46-ton sample of Lower Kittanning ``B`` Seam coal; completed eight primary integrated tests (PIT ... continued below

The main accomplishments of Custom Coals and the project subcontractors, during this period, included: continued purchasing small equipment and supplies for the circuit; procured a 46-ton sample of Lower Kittanning ``B`` Seam coal; completed eight primary integrated tests (PIT {number_sign}1--{number_sign}8) using the Pittsburgh No. 8 seam and the Grade-K and Grade-L magnetites; completed classifying cyclone tests using the Pittsburgh No. 8 and Lower Kittanning seams using a larger (0.5 inch) apex; completed data analysis on the four Grade-K magnetite ``closed-loop`` heavy-media cyclone tests; obtained a finer third grade of magnetite (Grade-M) with a MVD of approximately 3 microns; presented paper on the Micro- Mag project at the Coal Preparation, Utilization and Environmental Control Contractors Conference and a Poster Board Paper on the Micro- Mag Project at the Pittsburgh Coal Conference; and developed a method to modify all 5 Micro-Mag magnetic separators to approximately one third of their present size to better approximate commercial operation.
