application of high resolution x ray microcomputed tomography for coal Washability analysis
Minerals Engineering, 2018Co-Authors: Tuan D Nguyen, C. L. Lin, Anh V Nguyen, Jan D MillerAbstract:Abstract Float and sink testing is the standard laboratory method for determining the coal Washability characteristics using heavy liquids. In this paper, we describe an alternative technique for determining coal Washability using High-Resolution X-ray Microcomputed Tomography (HRXMT). Specifically, the application of HRXMT and specialized software have enabled us to determine the particle characteristics of coal samples with the considerable details needed for building Washability analysis. Coal samples taken from the feed streams to the dense medium circuits at two plants in Australia were obtained, characterized and used in the analysis. The coal samples were fractioned into the size and density fractions using sieves and heavy liquids as per the Australian Standard AS 4156.1-1994. The fraction-averaged densities were determined using helium gas pycnometry. The float and sink results were obtained for calibration and validation of the HRXMT results. Our results show that HRXMT can be used to perform coal Washability analysis. It provides a new methodology for non-destructive and non-toxic determination of coal Washability data. It is safe and fast. Significantly, the successful applications of X-ray computed tomography to perform coal Washability analysis would allow for developing an on-line coal Washability monitoring system, which would not be achievable with the traditional float-and-sink analysis.

Evaluation of a CT-based coal Washability analysis system under simulated on-line conditions
Mining Metallurgy & Exploration, 2002Co-Authors: C. L. Lin, J D Miller, G. H. LuttrellAbstract:The appropriate software and hardware necessary to adapt an X-ray CT analyzer for the determination of coal Washability was developed and successfully tested for well-characterized samples under laboratory conditions. Evaluation of the CT-based analyzer under simulated on-line conditions is also presented to verify the on-line capabilities of the newly developed X-ray CT analyzer for the control of coarse coal cleaning circuits. The investigation shows that the data obtained from CT Washability analyses compare favorably with experimental sink-float data. Further, image frequency was considered to evaluate the CT-Based coal Washability analyzer for simulated on-line conditions. Specifically, the number of observations (image spacing) needed for accurate sampling and the total time required to perform the calculations for a representative data set were determined.

development of an on line coal Washability analysis system using x ray computed tomography
Coal Preparation, 2000Co-Authors: C. L. Lin, G. H. Luttrell, Jan D Miller, G T AdelAbstract:Abstract Washability analysis determines the best separation results that can be achieved in the operation of coal preparation plants. Unfortunately, there are no on-line techniques for determining this most fundamental information. It now appears possible to determine coal Washability on-line through the use of X-ray computed tomography (CT) analysis. This paper presents the results for the development of a CT-based, on-line coal Washability analyzer. The development of appropriate hardware and software necessary to adapt a CT analyzer for use in determining coal Washability is discussed. Testing of the analyzer using well characterized coal samples is presented.

characterization of Washability of some mexican coals
Coal Preparation, 1999Co-Authors: C. L. Lin, J R Parga, Jaroslaw Drelich, Jan D MillerAbstract:Coal samples from the Mexican coal mines which supply coal to the power plants situated in the U.S.-Mexico border area, were collected and analyzed for chemical composition and separation characteristics. The analytical data indicate that the Mexican coals usually have a low or moderate sulfur content, l.3–2.5wt%. The pyritic sulfur accounts for 38 to 77% of the total sulfur content, depending on the sample source. Rejection of the pyritic sulfur (as well as ash) using sink-float techniques was evaluated in this study. Washability analyses for selected coal samples (2.00 × 0.841 mm and 0.841 × 0.595mm) from Micare, Palau and Pocito Tec mines, using heavy organic liquids with a density from 1.3 to 2.0g/cm3, were carried out. Also, the coal Washability curves were constructed for Micare coal for 25.4 × 12.7 mm and 12.7 × 6.3 ram particle sizes using the X-ray computed tomography (CT) technique. The results indicate that coal samples from Micare, Palau and Pocito Tec regions can be classified as easy to clean.
