Tabas mines in Iran have coal sources which are suitable for use in metallurgy industries as coking coal. But the high sulfur content of this coal imposes severe limitations on its utilization as the sulfur oxide gases evolved from the combustion of high sulfur coals result in acid rains and corrosion of equipments. In this work, attempts have been made to reduce sulfur from high sulfur coa...

In today’s operating environment many conventional cleaner circuits struggle to produce final grade concentrate with acceptable levels of non-sulfide gangue and/or penalty elements. This is primarily due to poor selectivity and the entrainment of gangue, and is further exacerbated by the processing of lower grade ores with more complex mineralogy that require finer grinding for liberation. In n...

The relation between rate constant k1 and absolute temperature T for graphite, anthracite, coal floated with only frother was investigated using combined theoretical empirical approaches. It determined that the lnk1 1/T is curvilinear requires a polynomial of second degree sufficient approximation experimental data points. Therefore, well-known Arrhenius formula chemical reactions, predicting l...

A novel froth image analysis based production condition recognition method is presented to identify the froth phases under various production conditions. Gabor wavelet transformation is employed to froth image processing firstly due to the ability of Gabor functions in simulating the response of the simple cells in the visual cortex. Successively, the statistical distribution profiles based fea...

The froth flotation technique can be considered one of the most efficient methods for separation minerals. Prior to utilizing any physicochemical method, size mined ore must decreased facilitate release valuable materials. This practice, along with increased exploitation ores that carry fine mineral particles caused production and ultrafine which are difficult recover classical enrichment metho...

Presence of microplastics in waste streams and the environment is a challenge much recent concern. Bubbles are used for solid–liquid separation froth flotation dissolved air (DAF). Bubble-particle interactions key understanding removal efficiency particulates. Limited studies provide in-situ characterization particle size distribution, shape concentration before after flotation. The use microbu...
