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 …

Shatter is a very pure cannabis concentrate that is typically translucent and very brittle, like glass candy. It looks a lot like amber. Shatter will have roughly the same potency as the other concentrates but lacks terpenes. For this reason, it is an ideal concentrate for dabbing. Read more about how to make and use shatter.
