Copper is a non‐ferrous base metal, which comprises 50 ppm on average in the Earth's crust [12]. The average grade of a copper deposit for exploitation is approx. 0.4% (open cast mines) and 1–2% Cu (underground mines), with many other valuable minerals and gangue minerals [12]. Flotation is the most extensively used conventional …
However, low-grade ores need to be beneficiated before they can be used to make steel. To meet the size specification required for the high-grade DSO products and liberate the gangues from the low-grade ores, run of mine ores are often subjected to various stages of crushing and screening operations. 8.2.1. Crushers

A normal body temperature is typically described as 98.6 F (37 C) but can range from 97 F (36.1 C) to 99 F (37.2 C). A low-grade fever is often the first sign of an infection. When the body temperature is normal, infectious bacteria and viruses are able to thrive. A fever is the body's way of creating a hostile environment to help neutralize them.
