Mineral Copper Ores Characterising

Higher mass recoveries are observed for the mids size fractions and similar to what is observed for the coarse fraction, Ore-A produces higher concentrate masses compared to Ore-B. Fine size fraction (75-38 m) When the mean particle size is further reduce from 106 m to 53 m, the fitted trend lines start to fall on the same line, indicating that the average mineral recoveries for both deposits are very similar

This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to blend the ores mined

Spectral characteristics of propylitic alteration minerals

Short-wave infrared (SWIR) reflectance spectroscopy is a quick and effective method of detecting and characterising hydrothermal alteration associated with ore deposits, and can identify not only mineral species but also changes in the major element composition of minerals. Porphyry deposits represent large accumulations of valuable metal in the Earth's crust and have extensive alteration

Copper. Copper (Cu) is an extremely useful industrial metal that is ductile (capable of being drawn into wire), malleable (capable of being hammered and molded) and an excellent conductor of electricity (only silver is better). Copper is found in many minerals that occur in deposits large enough to mine

interest in an ore is referred to as the grade of a deposit. To be graded, however, a mineral deposit must attain a minimum size, because no matter how high its grade, a deposit must contain enough ore to pay for the equipment, labor, and cost of extraction. The minimum concentration needed to extract the ore at a profit is known as the cut-off
