Minerals Free Full Text The Behaviour of Siderite

Little is known of the influence of fluxes on the nature and the intensity of burning in coal-waste heaps. To gain some insight, two siderite samples, one each from coal-mining waste heaps in Upper- and Lower Silesian Coal Basins (Poland), were heated under identical conditions in a thermal chamber coupled to a powder X-ray diffractometer. Differences in the behaviour of siderite phase and the ...

Advancing productivity and local sourcing for Tata Steel

Advancing productivity and local sourcing for Tata Steel

The more ash removed, the higher the quality of the coal. Typically, when removing ash content from coal, a portion of the coal becomes usable and a portion becomes waste. Using NALFLOTE in the ash removal process helped improve the recovery of usable product while also reducing the amount of coal that is wasted at the end of the process.
