Unique chemical helps salvage iron ore from mining waste

“Some iron ore processing plants in the Pilbara experience issues separating valuable iron ore from undesired materials in wet processing situations,” Professor Leong said. "We have demonstrated a more efficient way of extracting iron ore from waste, which will reduce material thrown away in tailings dams and save millions of dollars per year."

Environmental impact of iron ore mining Wikipedia

Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH)·n(H2O)) or siderite (FeCO3). Roughly 98% of iron ore on the global market is used in iron and steel production. Common methods of extracting the iron ore consist of blasting, drilling, or general excavating, Most iro

Metal Types and Recycling Process

Jun 25, 2019· Steel and iron are the most recycled materials in the world due in part to the opportunity to recover large structures as well as the ease of reprocessing. The use of magnets in the sorting process enables recyclers to easily separate them from the mixed waste stream. Every year, around 400 million tons of metal are recycled worldwide.

According to the above discussion, RDF-500 was used to replace coke breeze in the iron ore sinter process. In this experiment, 0–40% coke breeze was replaced with RDF-500 and the calorific value of the input fuel was equal. The influence of RDF-500 substitution ratio on the sintering speed was presented in Fig. 2. It was found that the
