Acid mine wastewater treatment using electrocoagulation
The electrocoagulation process occurs when the anode releases Al ions as an active coagulant into the solution to form floc, which binds contaminants and particles in acid mine wastewater. This could remove 99.95% of Fe in the case of wastewater from the iron ore beneficiation plant. However, until now, there are not many Al-Al electrodes usedIdiomorphic chromite is the only ore mineral appearing in economic quantities. The average content of the ore is 26% Cr 2 O 3 and the Cr/Fe ratio is 1.55. The Kemi chromium mine is an open-pit mine with a waste rock to ore ratio of 5.5:1. At Kemi, the ore from the mine contains 11% iron and 25.5% Cr 2 O 3.Chromite ore beneficiation: prospects and challenges

Beneficiation of Clay-Rich High-LOI Low-Grade Iron Ore
The unutilized iron ore fines (IOF, − 10 mm, 45% to < 60% Fe(T)) left at various mine sites during blasting and processing are rich in goethetic-hematite associated with high clay and considered a potential iron ore resource. The variation of loss on ignition (LOI) from mines to mines is based on the goethite and clay mineral content. The clay The earliest attempts to float iron oxide minerals involved the use of anionic collectors such as oleic acid or sodium oleate. Such a process was used at the Cuyuna Range plant which processed manganiferous iron ore in 1931. One of the successful applications of anionic flotation process was the iron ore flotation plant at Iron Ore Processing, General SpringerLink

The plant separates closed-circuit crushed ROM into −31.5 Use of indigenous microorganisms isolated from an iron ore deposits makes the process cheaper, flexible, and environment-friendly. Iron ore beneficiation can be brought about through three approaches, namely, selective dissolution, microbially induced flotation, and selectiveIn India, the tailings of iron ore beneficiation are dumped in slime ponds, which is a major environmental concern. In the present study, a new beneficiation circuit was designed to recover the valuable minerals from the tailing effectively.

Existing and New Processes for Beneficiation of Indian Iron
The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional The plant was designed for a rated throughput of 55 million tons per year (Mta). The major part of the mined hematite iron ore is essentially contaminated with clay components and therefore requires wet processing with three comminution stages. A total of 6 parallel lines process 9500 t/h of ore.Advances in screening technology in the mining sector

Comminution and classification technologies of iron ore
Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.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 Beneficiation of Magnetically Separated Iron
