Comprehensive investigation of the liberation characteristics of pyrite and other mineral matter from coal. [Semi-annual report], January 1, 1996--June 30, 1996

PDF Version Also Available for Download.

Description

The objectives of this project are: (1) Develop a set of laboratory techniques for the quantitative measurement of the liberation spectra in samples of coal particles in the size range 50 {micro}m - 1 mm. Three-dimensional spectra will be required to account for the mineral matter and pyrite separately. (2) Establish, experimentally, the Andrews-Mika diagram for a number of typical U.S. coals and to develop an appropriate parameterized description for the Andrews-Mika diagram so that it may be determined easily and quickly for coals of different origin and different type. (3) Establish an effective and reliable simulation technique so that ... continued below

Description

The objectives of this project are: (1) Develop a set of laboratory techniques for the quantitative measurement of the liberation spectra in samples of coal particles in the size range 50 {micro}m - 1 mm. Three-dimensional spectra will be required to account for the mineral matter and pyrite separately. (2) Establish, experimentally, the Andrews-Mika diagram for a number of typical U.S. coals and to develop an appropriate parameterized description for the Andrews-Mika diagram so that it may be determined easily and quickly for coals of different origin and different type. (3) Establish an effective and reliable simulation technique so that liberation of both pyritic sulfur and ash during comminution operations can be modeled and the operation of coal preparation facilities simulated. These models will be incorporated into a computer simulation system for coal cleaning plants. During this past quarter, a sample of Pittsburgh {number_sign}8 coal was crushed using ultrasonic milling and the progeny fractionated and analyzed, and an Andrews-Mika diagram constructed. While this diagram is qualitatively similar to Andrews-Mika diagrams established for other mineral systems, it illustrates that ash is liberated comparatively slowly during comminution.
