Processing and Analysis of Native Copper Ore Samples
-
ABSTRACT
Through the experiments of sampling, sizegrading, screening, splitting and homogeneity test for the native copper ore samples from northeast Yunnan province, a sample processing procedure was established. After rough and medium crushing and screening out the grains with grain size 2 mm screen (>95% is native copper), the sample was rod grinded, passing through 0.246 mm(60 mesh) screen, splitting and prepared to 0.074 mm(200 mesh). Atomic absorption spectrometry, iodimetry and iodinefluorine methods were selected for copper analysis with good accuracy, reliability and economical efficiency.
