introduction : Phosphate rocks are vital non-renewable resources and are essential components in agricultural fertilizers and phosphorous-based chemicals [1-4]. About 95% of the phosphate produced around the world is consumed in fertilizer industry [5, 6]. Phosphate deposits can be divided into three groups (і) sea sediments, (іі) igneous and …
Low-grade iron ore received from the West Singhbhum area of Jharkhand state in India was used to develop a beneficiation flow sheet to remove alumina (Al2O3 ) and silica (SiO2 ) from the ore to get iron (Fe)-rich product for steel plants.
The beneficiation of iron ore has witnessed a remarkable evolution over the years, propelled by advancements in technology and a deepening understanding of ore characteristics.
Coagulating sedimentation and oxidation treatment of process water in iron ore flotation of Yuanjiacun iron mine had been studied. The process water of this mine carried residual polyacrylamide (PAM), poly (diallyldimethylammonium chloride) (PDADMAC), and Ca2+ from the flotation and caused decrease of the iron flotation recovery or grade of the …
Beneficiation begins with the crushing and grinding along with wet or dry classification of extracted ores in preparation for further activities for the enhancement of iron content of the ores. Crushing and grinding is a multi staged process and may use dry or wet ore feed.
Beneficiation involves milling, magnetic separation, flotation, gravity concentration, thickening, filtering, and agglomeration to produce iron ore concentrates. Wastes include waste rock, tailings, and mine water. Management includes waste rock piles, tailings impoundments, and mine reclamation.
Process water collected from the iron ore beneficiation plant was treated by electrocoagulation (EC) process to make it suitable for reuse or safe for discharge.
The effectiveness of the flotation technique is dependent on four factors: the degree of oxidation of the ore, the number of copper minerals present, the nature of the gangue and the presence of iron sulphides. There are some other important factors such as the particle size, minerals compatible with the reagents and the condition of the water.
