Manganese is considered a relatively rare metal as concentrations of it in ore of commercial importance are geographically limited. In nature, manganese is found in the form of oxides, carbonates, and silicates. Manganese ores are complex in the sense that they not only consist of a complex oxide mineral assemblage but these minerals are also very finely inter …
The specific gravity of water is defined as 1. Materials with a specific gravity greater than 1 are denser than water, while those with a specific gravity less than 1 are less dense. To determine the specific gravity of a substance, the mass of a given volume of the material is divided by the mass of an equal volume of water.

Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In 2019, the global annual …
dust loss and increased performance of the furnace are achieved. A narrow size.distribution has the adiitage of increasing the charge permeability and the gas distribution becomes more uniform. Figure 3.3 shows that the degree of reduction decreases with increase in average size of iron ore. Fig. 3.3 : Effect of size of ore on degree of reduction.
Due to the presence of high level of gangue minerals, the iron ore slimes are discarded as waste material in storage pond (Manna et al, 2011). Indian iron ores are typified by high iron content ...
It came from a placer. Gold has specific gravity of about 19.3 and quartz has specific gravity of 2.7. The specific gravity of a mineral depends, in part, on how its atoms are packed together within a crystal. For example, the …

The specific gravity of iron ore is higher than its gangue. The specific gravity of common iron ores are given with iron percentage in it. (Table 2). The common earthy impurities or gangue attached with iron ores have lower specific gravity like, C alcite/ Limestone (2.70 -2.75), Gibbsite (2.67), C lay/Shale (2.65), Quartz & Calcite (2.35).
The laboratory analysis of ore samples reveals that mostly specific gravity values of ore samples are in a range of (2.65 - 4.5) (Table. 2) and the average value is (3. 73).
