Reduction of Sulfur and Ash from Tabas Coal by Froth Flotation
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...
متن کاملHarvesting of algae by froth flotation.
A highly efficient froth flotation procedure has been developed for harvesting algae from dilute suspensions. The method does not depend upon the addition of flotants. Harvesting is carried out in a long column containing the feed solution which is aerated from below. A stable column of foam is produced and harvested from a side arm near the top of the column. The cell concentration of the harv...
متن کاملFroth flotation of phosphate rock
The development of froth flotation is traced from its earliest-known use through the discoveries leading to the present knowledge of the science. The factors influencing the flotation of non-sulfide and non-metallic minerals are discussed, and the machines used in commercial flotation operations are described. Experimental work on the flotation beneficiation of phosphate rock is presented as an...
متن کاملEffect of Water Quality on Froth Stability in Flotation
In flotation, the froth structure and froth stability are known to play a significant role in determining the mineral concentrate grade and recovery. Froth stability is not only depending on the type and amount of the frother used, but also on the amount and nature of the suspended particles. Furthermore, there are other parameters such as quality of water which are not yet fully understood. In...
