This book was released on 1993 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: In dissolved-CO2 flotation, ultrafine bubbles are generated by CO2 dissolved in water. The ultrafine bubbles have the potential to improve the separation efficiency in fine coal cleaning. Chemicals will be used prior to or during dissolved-CO2 flotation to improve the separation efficiency of pyrite and other minerals including trace metals from coal. Chelating agents will be applied to clean coal to further reduce the trace metals from coal. During this period, the project planning has begun. A 3in.-diameter packed column has been ordered. This column will be modified for use in dissolved-CO2 flotation. Clean and waste coal samples of Illinois No. 6 coal have been scheduled to be picked up from Ohio Coal Testing and Development (OCTAD) facility.

Available in PDF, EPUB and Kindle. Book excerpt: In order to develop additional confidence in the conceptual design of the advanced froth flotation circuit, a 2-3 TPH Proof-of-Concept (POC) facility was necessary. During operation of this facility, the ICF KE team will demonstrate the ability of the conceptual flowsheets to meet the program goals of maximum pyritic sulfur reduction coupled with maximum energy recovery on three DOE specified coals. The POC circuit was designed to be integrated into the Ohio Coal Development's facility near Beverly, Ohio. OCDO's facility will provide the precleaning unit operations and ICF KE will add the advanced froth flotation circuitry. The work in this task will include the POC conceptual design, flowsheet development, equipment list, fabrication and construction drawings, procurement specifications and bid packages and a facilities.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of this research effort is to improve the efficiency of fine coal flotation in preparation plants above that of currently used conventional cells. In addition to evaluating single-stage operation of four selected advanced flotation devices, the project will also evaluate them in two-stage configurations. The project is being implemented in two phases. Phase 1 comprises bench-scale testing of the flotation units, and Phase 2 comprises in-plant, proof-of-concept (POC), pilot-scale testing of selected configurations at the Cyprus Emerald preparation plant. The Task 5 report presents the findings of the Phase 1 bench-scale test results and provides the basis for equipment selection for Phase 2. Four advanced flotation technologies selected for bench-scale testing are: Jameson cell; Outokumpu HG tank cell; packed column; and open column. In addition to testing all four of the cells in single-stage operation, the Jameson and Outokumpu cells were tested as candidate first-stage cells because of their propensity for rapid attachment of coal particles with air bubbles and low capital and operating costs. The column cells were selected as candidate second-stage cells because of their high-efficiency separation of low-ash products from high-ash feed coals. 32 figs., 72 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: The advanced flotation techniques, namely column flotation, have shown potential in obtaining a low ash, low pyritic sulfur fine size clean coal. The overall objective of this program is to evaluate applicability of an advanced flotation technique, 'Ken-Flote' column to recover clean coal with minimum mineral matter content at greater than 90 percent combustible recovery from two Illinois preparation plant waste streams. Column flotations tests were conducted on the flotation feed obtained from the Kerr-McGee Galatia and Ziegler No. 26 plants using three different bubble-generating devices: sparger, gas saver and foam jet. Each of these devices was tested with three different frothers and various column-operating variable to provide maximum combustible recovery, minimum product ash and maximum pyrite rejection. For the Galatia slurry, the column provided a clean coal containing 5 percent ash, 0.48 percent pyritic sulfur at combustible recovery averaging 90 percent. In other words, about 90 percent ash and about 75 percent pyritic sulfur rejection were attained for the Galatia slurry. Pilot plant studies on this slurry basically obtained results similar to the laboratory studies. For the Ziegler No. 26, slurry column flotation provided a clean coal containing about 5 percent ash, 0.44 percent pyritic sulfur at more than 90 percent combustible recovery. The ash and pyrite sulfur rejection was about 85 percent and 65 percent, respectively.
