The firms' Intelligent Recovery Unit (IRU) project received funding from Rio Tinto Group's sustainable water treatment challenge program, which may give them up to $2 million of co-funding ...
Residual mining wastes after reuse or resource recovery are typically discarded at specific sites such as tailing ponds. If wastes are not disposed of properly, …
They concluded that improvements in iron ore mining and direct water consumption are vital in water reduction. Leenes et al. found a high WF of electricity production in a steel mill. So their recommendation for reducing WF was to replace energy sources with sources of lower WF, such as solar, wind, and geothermal energy. ...
Iron ore tailings (IOTs) are an important solid waste in the mining industry, which can pollute the environment and endanger human health. However, the disposal and high value-added utilization of iron tailings have always been a challenge. Notably, superconducting high-gradient magnetic separation (S-HGMS) technology is a promising …
Present strategy for the management of wastewater from iron and steel plants includes conventional methods of wastewater treatment such as sedimentation to …
Recovery of phosphorus from mining wastewater could reduce the dependency on the global phosphate rock market [3]. Phosphate is an inorganic salt of phosphoric acid and found naturally as a phosphate rock [34, 52]. Phosphate can be found both as phosphate rock and potash ore. Phosphate rock is an igneous rock containing
In current processes, the mining industry generally adds lime to the wastewater to purify it. While often effective, the key issue with this method has been the volume of sludge that forms and the ...
In 2022, her company Nibeenabe piloted its device for remediation and attenuation of multiple pollutants (DRAM) technology to filter the tailings from a Madre de Dios mine extracting commodities that would otherwise be wasted. Large amounts of silver, copper, molybdenum, chromium, cobalt and other metals were recovered, according to …
Reuse water can affect the recovery efficiency of ore flotation. •. This is due to interferents in the water such as ions and partially degraded flotation reagents. •. This …
The mining of ion-adsorption rare earth minerals or ores generated a large amount of wastewater containing rare earth elements at low-concentration, resulting in continuous environmental pollution. For this problem, our study prepared an efficient, recyclable MgO/MgFe 2 O 4 magnetic adsorbent, synthesized by a template method and …
