In the iron ore industry, the recovery of fine particles is an important concern in terms of process performance and production costs and perennial efforts are devoted to increase the efficiency in handling these fines. The Reflux Classifier (RC) is a relatively new technology that is mainly used in the coal and minerals industries.
Iron ore is the basic raw material for iron and steel making. India is among the leading producers of iron ore in the world and produces about 150 million tons per annum (U. S. []).The total reserves of iron ore in India is around 28.5 billion tons, of this hematite ore is considered to be the most important iron ore because of its high grade quality and lumpy nature.

The processing of tailings in iron ore beneficiation plants is currently less conventional. The Roy Hill facility employs 5 "up-current" modules (UCC) with spiral classifiers. Today's processing plants are increasingly using new-type classifiers, such as FL's REFLUX technology.
The beneficiation of low-grade iron ores is a key research and development topic in the mineral processing industry. The gradual exhaustion of high-grade iron ore reserves, and rising consumer iron and steel demand globally necessitate efficient low-quality iron ore beneficiation to meet steelmaking quality requirements. This comprehensive review explores …
In India, there are over 34,000 people working in iron ore mining. The domestic iron and steel, sponge iron, ferrous alloys, and alloy steel sectors consume about 47% of the total output. Iron ore exports totaled 29.5 million metric tonnes during the years 1999 and 2000, with China and Japan each receiving 22% and 50% of such shipments ...
Furthermore, the Reflux™ Classifier achieved an iron ore grade of 60% and the reverse flotation one of 47%. The Reflux™ Classifier in other words clearly performed better in this test.
The optimal deep learning model consisted of five hidden layers for the DNN predicting the ore production and four hidden layers for the DNN predicting the crusher utilization, each with 40 hidden neurons [].The developed final deep learning model was evaluated for its ore production and crusher utilization prediction performance over ten days at the mine.

The low-grade clay-rich -1.0 mm fraction of fine iron ores have often proved difficult to upgrade and capital intensive to process when using traditional wet beneficiation technology including single or two stage hydrocyclone desliming, wet high intensity magnetic separation (WHIMS), spirals and final dewatering using fine screens. Very fine (<0.010 mm) clay-rich slimes simply …
Rough processing of iron ore employs dry methods which means that equipment is tuned to process large particles, but fine magnetic material less than a few tenths of a millimeter in size is not separated as efficiently. The relevance of this study is determined by the fact that dry beneficiation waste contains recoverable iron-bearing magnetite of commercial value. …
Iron ore is the core raw material used in the steel industry (Asadi et al., 2023).Steel products obtained from iron ore smelting have long been essential materials in industrial sectors such as shipbuilding, automobile manufacturing, railway construction, bridge construction, heavy industry, and machinery manufacturing (Yang et al., 2023).Therefore, iron ores are considered …
The iron mines of the Mesabi Range and the broader Lake Superior Iron Ore District were globally significant, serving as the primary producer of global iron ore for more than a half-century, and providing nearly half the world's supply of iron ore during the years following World War II (Forbes 1953). But as these Lake Superior ore bodies ...
The smaller, faster ore will be able to travel a longer distance than the large particles before the rakes or spiral will pull the ground material back towards the coarse ore discharge. If the Classifier is able to pull the course ore backwards further than it can travel forwards, then eventually the bigger particles will be pulled all the way ...
