The role of chemical reagents to reduce moisture in iron ore fines is explored in the present work which includes ionic and non-ionic surfactants.
Water plays a crucial role in mineral beneficiation, and thus dewatering the tailings from mineral processing plants has great importance. This paper discusses the influence of chemical conditions (pH, flocculants, surfactants, and coagulants) on the filtration performance of iron ore tailings. The results indicated that Ca 2+ and Na + ions …
Iron Ore; Commentary. Commentary; Editorial; ESG. Indigenous Issues; ... miners cannot afford to have profits washed away and that's why pumps and the technology associated with dewatering …
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
Therefore, dewatering after 1250 kPa filtration has no further adhesion-increasing effect. For the iron ore tailings, 5 kN·m −2 corresponds approximately to 25 cm cake thickness by assuming a …
Ore Concentrate filtration. What is the filtration or dewatering of ore concentrates? After mine excavation, the mining process, forecasts to separate the valuable ore like iron ore, copper, zinc, molybdenum, coal concentrate etc.. from the …
In this paper, a control strategy for an iron ore concentrate dewatering process was developed and evaluated by employing a dynamic model. The proposed …
