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, …

What is Muscovite? Muscovite is the most common mineral of the mica family. It is an important rock-forming mineral present in igneous, metamorphic, and sedimentary rocks.Like other micas it readily cleaves into thin transparent sheets. Muscovite sheets have a pearly to vitreous luster on their surface. If they are held up to the light, they are …

Scratch test Gold is a very soft element, so scratching it will leave marks. Use a knife to try and scratch the surface of your rock. If it's gold, you'll see scratches. Pyrite will be too hard to be affected, and mica will flake off when scratched. If you don't have a knife handy, scratch gold with a piece of copper (like a penny).
