Low-grade copper ore contains a small amount of copper (1% or lower) and a big amount of waste rock. The problem with low-grade copper is that it breaks down and melts more easily than copper ore.
Copper rich ores contain Relatively large amount of copper. Copper obtained from rich ores is from better quality than low-grade ores. A low-grade ore doesn't contain very high proportion of valuable copper
The metal (copper) extracted may be generally brittle and break easily.
It is very hard and very expensive to remove the copper from that ore.
break and melt easily
Through bioleaching, thermal decomposition, displacement, phytomining & electrolysis.
It's poor quality and not all the copper can be extraxted from it
No Slate is associated with a low-grade metamorphism

Not to be flippant, but a persistent low grade fever is most typically caused by a persistent, low grade infection. There's not a lot else I can tell you without more symptoms present.
