A review on the characterisation and processing of oolitic iron ores. Keith Quast, in Minerals Engineering, 2018. 3.7 Selective oil agglomeration. Uwadiale (1990a) used selective oil agglomeration to upgrade Agbaja oolitic iron ore from a feed value of 45.6% Fe to a concentrate containing 65% Fe at 89.3% Fe recovery. The ore was very fine ...
The paper also includes laboratory investigation on solar agglomeration of magnetite ores to understand the practicality of its commercialisation. In the last decade, several concentrated solar power (CSP) plants have been installed worldwide with over 300 MW capacity. New developments in the solar receiver systems and heat engines are ...
With uranium ores, the additional key benefit of agglomeration or wetting the ores as soon as possible is reduction in the dust emissions from conventional dry crushing circuits, which will provide cleaner and safer environment. Agglomeration is an integral part of new and future heap leaching uranium operations. Some of the new projects …
Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine …
With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional beneficiation techniques used to achieve a suitable concentrate for steel and other metallurgical industries. ...
