Minecraft 1.20 Ore Distribution (Graph)
The most optimal location for finding Copper Ore in Minecraft 1.20 is the Y level 48. Copper Ore has a significantly greater generation rate in Dripstone Caves. As such, Dripstone Caves occurring at Y level 48 have the highest probability of containing Copper Ore. It can also be found in Copper veins generated above Y level 0.
Characterization study and recovery of copper from low grade copper ore
The chemical constituents of as-received low grade copper ore sample was chemically analyzed and listed in the Table 1. The particle size distribution of ore sample was investigated using sieve analysis, and found that, the ore is fine in nature i.e., 51 % below 125 μm as shown in Fig. 1. The qualitative analysis of chemical elements present ...
Experimental Evaluation of a Mineral Exposure Model …
Particle-Size Distribution for Heap Leaching Copper mineral inclusions have a certain size distribution (grain-size distribution), N(X), where N is the weight fraction of grains for particle size X (Miller et al. 2003). The heap leaching process should be designed to crush the ore so that the copper mineral grains are exposed and can be leached.

A similar issue can exist when a wide range in particle size distribution results in segregation of particles. ... Le Capitaine has engineered many of the agglomeration drums serving the mining industry today, including copper ore drums for the world's largest and most environmentally advanced copper mine.
Estimating Ore Particle Size Distribution using a Deep Convolutional
The ore feed size may in some cases be inferred by applying parameter estimation to operational data (Olivier et al., 2012), but a more direct approach is to monitor images of the feed and inferring the size distribution using computer vision. ethods exist that calculate the size distribution from input images, see e.g. Zhang et al. (2013) and ...
