plus five or more confirming ions, selected combinatorially, against the sample spectrum. In most cases, there were seven unique ions that met the relative abundance criterion. When the ion signals for these ions comaximized and produced RA differences ≥30% compared to known ion ratios, the pattern was new and cataloged. A more thorough ...
Coal waste was collected from the coal dump deposit of the "Verdinho mine," Santa Catarina State, Brazil, which extracts the Barro Branco seam. The material was submitted to a laboratory dense medium separation processing, using organic liquids, which aimed at obtaining a fraction with relative density between 2.4 and 2.8 [27].
The Advanced Coal Processing Program focuses on both enhancing the value of coal as a feedstock and developing new high-value products derived from coal. Research includes testing of laboratory- and pilot-scale technologies to produce upgraded coal feedstocks and additional revenue-producing products.

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of ...
than 2.3. Coal and ash are mixed across all specific gravity categories and particle sizes. Coal-cleaning technologies and machines typically use specific gravity differences between coal and ash to separate the two. The exception is the flota-tion process, which uses differences in surface properties of coal …

Meanwhile, the use of process and saline waters in coal flotation has also attracted great interest for many years as the process water can be re-used and the accumulated salt ions available in water can enhance coal flotation. Since the researchers (Majer et al., 1934) discovered in 1934 that that coal could be floated with the increase in salt
A further, and more specific object is to provide a novel, highly economical and efficient process, utilizing a contact mass which can be used to remove the ions of a metal, or the ions of a plurality of metals, from a flowing aqueous stream within which the ions of the metal, or ions of a plurality of metals, is dissolved at high loading ...
the elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the coal seam, (5) loading and transporting the coal, (6) backfilling with spoil and …

Ion concentration measurement or ion-specific (ISE) measurements can be performed in every laboratory for a variety of sample types including water, food and beverage, pharmaceuticals, and biological samples. To evaluate a sample's ion-specific performance, the best resource is slope S, also known from pH measurement.
Abstract. The goal of this project was to produce a high purity, separated (>90%) rare earth oxide (REO) product from coal-based sources. This product was achieved using the following three steps: Battelle's ADP: The ADP process involves pretreatment of ash (milling and caustic leaching), leaching of pretreated ash with nitric acid, roasting of loaded acid solution containing REE, and water ...

Coal mine goafs can be used to store and purify mine water; therefore, they are important for mitigating the environmental impact of mining on ecologically fragile areas in Western China. Coal gangue in goafs can reduce turbidity, suspended matter, total hardness, and chemical oxygen demand (COD) in mine wastewater. Because gangue in goaf areas is rich in clay minerals, they serve as ion ...

Ocean acidification is sometimes called "climate change's equally evil twin," and for good reason: it's a significant and harmful consequence of excess carbon dioxide in the atmosphere that we don't see or feel because its effects are happening underwater. At least one-quarter of the carbon dioxide (CO 2) released by burning coal, oil and gas doesn't stay in the air, but instead ...
