Bench scale testing of micronized magnetite beneficiation. Quarterly technical progress report 3, July--September, 1993

Description: This project is aimed at development of a process that, by using ultra fine magnetite suspension, would expand the application of heavy media separation technology to processing fine, {minus}28 mesh coals. These coal fines, produced during coal mining and crushing, are separated in the conventional coal preparation plant and generally impounded in a tailings pond. Development of an economic process for processing these fines into marketable product will expand the utilization of coal for power production in an environmentally acceptable and economically viable way. This process has been successfully researched at PETC but has not been studied on a continuous bench-scale unit, which is a necessary step towards commercial development of this promising technology. The goal of the program is to investigate the technology in a continuous circuit at a reasonable scale to provide a design basis for larger plants and a commercial feasibility data.

Bench scale testing of micronized magnetite beneficiation. Quarterly technical progress report No. 1, April--June 1993

Description: This project is aimed at development of a process that, by using ultra fine magnetite suspension, would expand the application of heavy media separation technology to processing fine, {minus}28 mesh coals. These coal fines, produced during coal mining and crushing, are separated in the conventional coal preparation plant and generally impounded in a tailings pond. Development of an economic process for processing these fines into marketable product will expand the utilization of coal for power production in an environmentally acceptable and economically viable way. This process has been successfully researched at PETC but has not been studied on a continuous bench-scale unit, which is a necessary step towards commercial development of this promising technology. The goal of the program is to investigate the technology in a continuous circuit at a reasonable scale to provide a design basis for larger plants and a commercial feasibility data. The project is divided into eight tasks which include design, construction, operation and testing, sample analysis, evaluation, and decommissioning. Coal will be received from three different mines and processed through the bench scale{backslash}e plant. Testing has been split into three phases: (1) Component Testing which will examine each of the major components independently, optimize, and compare performance to lab scale tests, (2) Integrated Testing will provide evaluation of the components operating as an integrated system, and (3) Extended Tests will utilize coal from each of the three mines to determine ash and sulfur removal on each candidate feedstock. Accomplishments for the quarter are presented for following tasks: project and test planning, and engineering and design.
