In this paper, a novel iron ore agglomeration process is presented that utilizes concentrated solar energy instead of carbon intensive coke and natural gas used by the conventional iron ore agglomeration processes such as sintering and pelletisation. This way, carbon dioxide emissions can be reduced in ironmaking by replacing the heat …

The main advantage of a fluidized-bed technology is that fine iron ore can be directly charged to the process without prior treatment; it does away with agglomeration and its concomitant cost, a step practised in blast-furnace, COREX {sup R} and MIDREX {sup R} processes.
The motor truck has become the cheapest means of long-distance freight movement. False. Agglomeration economies reflect cost savings that result from the clustering of economic activities. True. Transportation costs are central concerns in …
The production costs for South African iron ore producers are approximately double that of the largest iron ore producers, namely, Brazil and Australia. This in conjunction with volatile commodity prices, necessitated a cost-sensitive beneficiation strategy for low-grade hematite to sustain the industry and extend life of mine.

Characterisation, beneficiation and agglomeration studies were carried out to develop a utilization strategy for typical Indian low grade manganese ore fines. The major mineral phases found are pyrolusite, hematite, goethite, clay, feldspar and quartz. QEMSCAN and Sink–Float studies suggested that 40% of manganese minerals are in …
Our Agglomeration Handbook is a comprehensive resource on tumble-growth agglomeration techniques, in which methods, processing considerations, and equipment are examined. Many of the world's top companies have come to rely on FEECO for the best in custom process equipment and solutions.
A project for a dedicated iron ore port with a capacity of up to 560 million tonnes per year is advancing in the north of Brazil.
The iron-ore fines that enter the BF need to go. through a pelletizing and sintering process. In other cases, such as the smelting reduction (SR) processes that use the fluidized bed ...
"Liberia, which was historically the largest exporter of iron-ore in Africa and the fifth-largest iron-ore producer globally, is described as one of the last underexplored regions in the world.
Based on reported prices for iron ore fines (62% iron content) imported into China (cost, insurance, and freight into Tianjin Port), the highest monthly average price during the first 9 months of 2021 was $214.43 per ton in June compared with the high of $155.43 per ton in December 2020.
Hence, to meet the growing steel demand, the demand for iron ore is also increasing. While, on one side reserves of good quality iron ore are depleting, on the other side the steel companies require better quality of iron ore with lower gangue content due to the addition of higher capacity blast furnaces for higher productivity, lower hot metal …
Agglomeration binder is the binder used for agglomeration in mineral processing. During mineral processing, usually an external force is applied to consolidate powder ore with the help of agglomeration binder, so that the mineral pellet will have the desired shape, particle size, mechanical strength, and roasting properties, in order to …
"Liberia, which was historically the largest exporter of iron-ore in Africa and the fifth-largest iron-ore producer globally, is described as one of the last underexplored regions in the world.
Afrimat's Commodities division was established in 2016 with the acquisition of an iron ore mine in the Northern Cape. The division focuses on consistently and reliably supplying quality iron ore and manganese to local and international markets. This is achieved by leveraging the group's core competencies in uniquely positioned iron ore mines, in …
Globally, the largest iron ore producers are Brazil, China, India, and Australia, producing approximately 70% of the world's iron ore, whereas in Africa, South Africa leads in iron ore production at 4%, followed by Mauritania, Algeria, and Liberia with inferred deposits of crude ore of approximately 250 million tons [ 3, 4 ].
Imports In 2022, South Africa imported $107k in Iron Ore, becoming the 78th largest importer of Iron Ore in the world. At the same year, Iron Ore was the 1150th most imported product in South Africa. South Africa imports Iron Ore primarily from: Namibia ($50.2k), Botswana ($10.8k), Australia ($10.4k), United States ($8k), and Netherlands ($6.66k).
In this paper, an overview of the existing solar thermal research on iron ore processing is provided. The paper also includes laboratory investigation on solar agglomeration of magnetite ores to understand the practicality of its commercialisation.
Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. In this chapter, the sintering process is first described to identify the key ...

By contrast, Finance Minister raised the export duty on iron ore to a flat 20 % from 15 % on iron ore lumps and 5 % on iron ore fines, in keeping with demands by the steel industry wanting more supplies of iron ore at low costs. The duty was subsequently hiked to 30 % uniformly on export of all types of iron ore.
South Africa is one of the world's largest producers of iron ore, with significant reserves of the mineral found throughout the country. In this article, we will take a closer look at iron ore production in South Africa, including the history, current state, and future outlook of the industry.
Agglomeration of Iron Ores. This book focuses on agglomeration, or the size enlargement process, of iron ores. This process sits at the interface of mineral processing and extractive metallurgy. The book begins with a discussion of raw materials preparation and the beneficiation process. It then describes fundamental principles of the sintering ...
The briquette, which is produced through the low-temperature agglomeration of high-quality iron-ore, could be used to replace sinters, pellets and granules in steelmaking, cutting greenhouse gas ...
This study focused on improving recycling of carbon-bearing dusts from integrated steel plants by the composite agglomeration process (CAP), in which four types of the dusts were prepared as pelletized feed, while the other raw materials were used as matrix feed for sintering to produce agglomeration product as a substitute for traditional …
Iron ore pellets are spheres of typically 8-16 mm to be used as feedstock for blast furnaces. They contain 64-72% iron and additional materials, which can adjust the chemical composition and metallurgical properties of the pellets.
ABSTRACT In steel industry and in mines, a significant amount of ultra-fines waste iron oxides and iron ore fines is generated. Utilizations of these fines are required to reduce the environmental hazards and conserve the natural resources. Some of these fines are normally used in sintering practice. However, sintering has a limitation of accepting …
