Bench-scale testing of the micronized magnetite process. Quarterly technical progress report No. 1, July--September 1994
The primary project objectives are: test the feasibility (ie., magnetite losses) of a fully-integrated, conventional wet-drum separator circuit for magnetite recovery. If losses are too high (greater than 10 {number_sign}/ton), we will try HGMS.; determine the impact of changing recirculating media quality on heavymedia cyclone performance. If losses are low (less than 5{number_sign}/ton), the magnetite changes will be insignificant. The only changes will then be degree of fine-coal contamination of the media. The testing will be done with 2 to 3 grades of micronized magnetite (differing sizes and perhaps qualities), and 2 to 3 different bituminous coals (Pittsburgh and a softer coal). The secondary objectives, in which Custom Coals is also interested, include: Test the application of drain and rinse screens down to finer sizes than previously tested (200 to 325 mesh); determine the feasibility of using single circuitry to feed a wider size range (28 {times} 325 mesh). During July 1994, Custom Coals, Int. and AMAX R&D signed the novation agreement switching the prime contract for the Micronized Magnetite Project to Custom Coals. However, no project work was performed during July and August, 1994. The major focus of the work performed in September was: Finalizing the Equipment List for major purchases; finalizing the Circuit Flowsheet and P&ID. This report summarizes the results from those efforts, and introduces the new project objectives, schedule, an budget. The final section contains the major priorities for the next quarter (October through December, 1994).
