The bench flotation tests were conducted in a Wemco machine equipped with a 3.9 L cell, using 1.5 kg iron ore aliquots in 50 % solids (w/w) pulps. The pulp was conditioned at 1250 rpm, initially with starch for 5 min and then with the collector and frother solutions for 1 extra minute, when it was diluted to 42 % solids for flotation.

Test work was conducted at the Chadormalu (the largest iron deposit in central Iran) iron flotation plant in Iran. In this plant around 2000 t/h ore containing approximately 55% Fe and 1% P (with magnetite, hematite and apatite as the valuable minerals) is treated to produce iron (with 67% Fe and 0.045% P 2 O 5) and apatite (with …
1. Introduction. Flotation is a selective process for separating minerals from each other based on particle hydrophobicity. The flotation separation efficiency depends on the recoveries of the mineral species by both true flotation and entrainment (Cilek, 2009, Neethling and Cilliers, 2009, Wang et al., 2015).Both chemical variables and …

Froth Flotation is one of the fundamental processes used in iron ore attainment. It involves various physical–chemical reactions, and its multivariate control is not trivial.
With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an …

Mechanical agitation flotation machines: These units contain an impeller that is mechanically operated to mix and distribute air into the slurry. This mechanical stirring encourages the float of minerals by fusing them with air bubbles. A part of the flotation cell of an inflatable flotation machine is inflated using an outside blower.
