Transforming iron ore processing ScienceDirect
In the recent past, iron ore resources from Brazil consisted of relatively high-grade iron ore, commonly processed via multi-stage crushing/screening, gravimetric concentration, magnetic separation, and reverse flotation. However, the high-grade iron ore reserves are in decline, resulting in the need to process the lower grade itabirite iron Porphyry-type deposits are the major sources of copper and molybdenum, and flotation has been adopted to recover them separately. The conventional reagents used for depressing copper minerals, such as NaHS, Na2S, and Nokes reagent, have the potential to emit toxic H2S gas when pulp pH was not properly controlled. Thus, in this Flotation Separation of Chalcopyrite and Molybdenite Assisted

Utilization of DTAB as a collector for the reverse flotation separation
Reverse flotation desilication is an indispensable step for obtaining high-grade fluorapatite. In this work, dodecyltrimethylammonium bromide (DTAB) is recommended as an efficient collector for the reverse flotation separation of quartz from fluorapatite. Its collectivity for quartz and selectivity for fluorapatite were also compared A combined process of flotation and high-gradient magnetic separation was proposed to utilize Yulong complex copper oxide ore.

Green hematite depression for reverse selective flotation separation
It was well-documented that reverse (cationic/anionic) flotation separation is the most comprehensive processing practice for enriching low-grade hematite ores, in which mineral liberations happenSeveral iron ore producers in Brazil employ reverse flotation separation of silica from low-grade iron ores for producing pellet-grade concentrates. It has been reported that the presence of gibbsite and clay as the major alumina-containing minerals in iron ores dictates the choice of beneficiation flow sheet.Minerals Free Full-Text Recovery of Hematite from Banded

Selectively Depress Copper-Activated Pyrite in Copper Flotation
Copper sulphide ore deposits are of great economic significance for copper extraction. In order to enrich copper sulphides, froth flotation at alkaline pH is typically applied to reject associated gangue minerals, in particular pyrite before the subsequent pyrometallurgical treatment to extract copper from copper sulphides [].The The flotation process is most widely applied to balance the P2O5 recovery ratio and cost. In this review, the dominant techniques for the beneficiation of phosphate ores are introduced. Moreover, the factors that affect the flotation of phosphate ore, including the properties of mineralogy, flotation reagents (depressants and collectors) Review on Beneficiation Techniques and Reagents Used for Phosphate Ores

Review of the Main Factors Affecting the Flotation of Phosphate Ores
The way to successfully upgrade a phosphate ore is based on the full understanding of its mineralogy, minerals surface properties, minerals distribution and liberation. The conception of a treatment process consists of choosing the proper operations with an adequate succession depending on the ore properties. Usually, froth flotation The process is to float molybdenum first, then grind to separate copper and molybdenum, and flotation molybdenum tailings to recover copper. 3. Equal flotation Process.
