Accurate basement delineation is crucial for mineral deposits where formation is associated with a paleo-basement topography, such as in detrital iron ore deposits. In such environments seismic surveys provide useful data to assist the mapping of the basement interface. A key stage of the process is identification of the first arrival of elastic waves at …
The work index of Muro iron ore was determined using the modified Bond's method also known as Berry and Bruce method. This study used iron ore obtained from Muro town, a community in Toto LGA, Nasarawa state as the test ore. Marble and Granite which was separately used as the reference ores were obtained from Muro environs. 100 g each of …
The structure characteristics and adhesive property of humic substance (HS) extracted with different methods were mainly studied by terms of elementary analysis, visible spectrum, FT-IR spectroscopy, viscosity, adsorption and pelletizing experiments. The results show that HSs extracted with new method (HS-a) own higher degree of …
Iron ore is regarded as the second most important commodity behind oil. As an essential input for the production of crude steel, iron ore feeds the world's largest trillion-dollar-a-year metal market and is the backbone of global infrastructure. To meet the growing demand for steel products, world iron ore production has increased dramatically since …
Comprehensive comparison of these three royalty levy methods indicates that the price-based method can most effectively protect the benefits of mineral resource owners and promote reasonable use of mineral resources.
As a result, accurate and effective forecasting of iron ore prices has become increasingly vital in managing project risk and developing profitable investment strategies. With the potential for severe and frequent price fluctuations, stakeholders must stay informed and up-to-date on the latest developments in the iron ore market.
Sample preparation is a critical step in the geochemical analysis, and complete sample dissolution is a pre-requisite for obtaining accurate and precise data for geological materials in most studies. Sample matrix, analytes of interest, the analytical technique, and intended purpose play a major role in selecting the optimum sample …
Further on, the synthesis of magnetite nanoparticles is extensively described by detailing the conventional and non-conventional methods. 2. Magnetite – morphologies, properties, and applications. Magnetite is the most common and utilized form of naturally occurring iron oxides, with the chemical formula Fe 3 O 4[32].
In parallel with these groups of researchers, a group of authors from Australia have developed an automated OM system for the characterization of iron oxide/hydroxide ore deposits: the Commonwealth Scientific and Industrial Research Organisation (CSIRO) Mineral Resources.
This paper reports the feasibility studies of the purification of a low grade iron ore taken from Tange-zagh mine in Bandarabbas region by gravity and mag-netic methods.
