Ground Oxidised Copper Ore

Effect of mineralogy on grindability

The three copper ores were mined from different mineralization zones within the same ore deposit and thus the experimental W i values of the distinct ores could be useful for the development of the geometallurgical model for that deposit (Mine, 2017; Mwanga et al., 2014). However, to account for the inherent variations in the orebody, many ...

Copper Trapdoor

Non-waxed copper trapdoors have four stages of oxidation (including the initial normal state). Lightning bolts can remove the oxidation on copper trapdoors. However, axes cannot be used in the same way they can with other copper blocks (because right clicking on non-waxed copper trapdoors while holding an axe will only toggle the trapdoor). Instead, …
