Particle size distribution for copper heap leaching,
unknown grain size distribution, texture/exposure, and spatial distribution in the ore particles. In order to build a heap for copper recovery, the mined ore is crushed to an appropriate particle size so that the valuable mineral grains are exposed and can be extracted.Effect of the particle size and microstructure,,01-03-2021· It was worth noting that more than 90% of the copper grain was exposed in the 4–1.6 mm particle size, while the copper grain exposure was only 58.72% in the 10–8 mm particle size. According to this deduction, the copper grain exposure of ore is obviously lower in coarser grain size.Particle Size Distribution of Copper Mine Tailings from,,The particle size distribution of the tailings are as shown in Table 1. Itcan be seen that the tail ings consisted mainly ofparticles of < 1000 /.Lm in size. On average, 99.64% of the tailings particles were in the < 1000 /.Lm size fraction, while 52.23%, 15.72% and 4.87% were in the < 125 pm, < 62.5 /.Lm and < 38 p.m size frac tions respectively.
