Vale is a global mining company that transforms natural resources into prosperity. Headquartered in Brazil and operating in around 30 countries, the company employs approximately 110,000 employees, including its own and permanent contractors.

Iron ore processing is a crucial step in the production of steel, one of the most essential materials in modern society. Iron ore, a naturally occurring mineral composed primarily of iron oxides, is mined and processed to extract iron for various industrial applications. This article provides a comprehensive overview of the iron ore …

Two different iron ore tailings replaced a natural quartz aggregate in the geopoly-mers' formulation. The hardened properties assessed were compressive strength, water absorption, apparent density ...

Approaches such as hydrogen-based direct reduction are being considered since they can drastically reduce the overall CO 2 emissions of the steel-making process. Here, we report an electrified process for reducing iron ore particles using atmospheric pressure hydrogen plasma powered by microwave energy.

The worldwide mining industry produces millions of tons of rock wastes, raising a considerable burden for managing both economic and environmental issues. The possible reuse of Fe/Mn-rich materials …

Reuse of wastewater is recognised in most water-scarce countries [ 6 ]. Instead of discharging industrial effluents into rivers and streams, reverse osmosis (RO) membranes can be used to treat the wastewater and …

Recycling and reuse of these high grade pellet fines from the waste stream are vital for the protection of high grade resources and cost reduction in integrated steel industries. In the present study, an attempt has been taken to reuse and utilize the iron oxide pellet fines through pelletization process to produce requisite quality of pellet.

Equitable access to water of the proper quantity and quality is a human right, and water reuse is a proven way to contribute to this goal.

This review paper explores available literature on the main technique s. of mining tailing recycling and reuse and discusses leading technologies, including the benefits and. limitations, as well ...

Request PDF | Reuse of iron ore tailings as an efficient adsorbent to remove dyes from aqueous solution | In this work, an iron ore tailings sample (IOT), collected from a tailings dam in Minas ...

Water was not reused extensively in the iron ore industry, but some concentration plants and mines did reuse water. Because the flow of water into and out of tailings basins often cannot be completely deter mined, the actual amount of water reused is …

Today, much of the steel we use is produced by recycling existing materials – for each ton of reused steel, we're able to save 120 pounds of limestone, 1,400 pounds of coke, and 2,500 pounds of iron ore, according to the American Iron and Steel Institute. There are two primary methods of creating steel with reclaimed scrap: through an EAF ...

Reusing and recycling construction products avoids or reduces waste and saves primary resources. By using materials that have a greater potential for reuse and recycling, it is more likely that the value of these products at their end-of-life will be realised and extended in future applications.

PHOENIX supplies a variety of high-quality equipment solutions for dewatering, classification, thickening, water clarification, water recycling and more.

The pollutants degradation rate of iron ore tailings–based heterogeneous catalysts is the main factor limiting its application. Herein, an iron ore tailings–based Fenton-like catalyst (I/W(3:1)-900-60) with a relatively fast catalysis rate was constructed by co-pyrolysis (900°C, 60 min holding time) of iron ore tailings and wheat straw with a …

The increasingly stringent European regulation and the ever-higher disposal costs currently affect manufacturing industries, leading them to strengthen their efforts in order to improve the recycling rate of their by-products and waste [ 1 ]. Iron- and steelmaking by-products result from the processes producing steel by two main routes: the iron ore-based …

Recycling - Ferrous Metals, Reuse, Upcycling: Ferrous products (i.e., iron and steel) can be recycled by both internal and external methods. Some internal recycling methods are obvious. Metal cuttings or imperfect products are recycled by remelting, recasting, and redrawing entirely within the steel mill. The process is much cheaper …

The fatty acid flotation of a difficult-to-float igneous phosphate ore (26.2% P 2 O 5, 15.4% Fe 2 O 3) was investigated through batch flotation tests in the presence of soda ash. The poor flotation of this otherwise high quality ore was attributed to very high concentrations of calcium and sulfate ions (about 1000 and 2000 mg/L, respectively) …

This process effectively recovers iron from IOTs without recovering other valuable metals, addressing some of the economic, environmental, and strategic challenges associated with mining. It enables iron recovery from tailings and contributes to the reduction of environmental impacts.

Therefore, recovering the waste heat adequately in sintering and cooling process is of great importance for energy conservation and emission reduction in iron and steel companies [3], [4], [5].
