In this study, systematic experiments are performed to measure the pressure drop of water-vapor two-phase flow in five microchannels with copper fins, which consist of nine or six channels and fins of copper . The porosities of the fins range from 0.78 to 0.82 and ratios of fin width to channel width range from 0.5 to 2.

CHAPTER 3 Production of high copper concentrates d comminution and fl otation (Johnson et al., 2019) The grade of copper ores is typically too low (0.5% e 2% Cu) for economic direct smelting. Heating and melting the huge quantity of largely worthless rock would require too much energy and too much furnace capacity. For this reason, all ores destined for …

percent of the mass, lose 9% of the copper to waste at a grade of 0.4% copper. The DMS simulation indicated that due to the large amount of near density material, unstable operation of the DMS plant could be expected. The inclusion of a DMS plant in the flow sheet was therefore not recommended. Comminution

Copper Ore. Copper ore usually contains about 0.5 to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size. The ore is processed by froth flotation comprising rougher and scavenger cells.

Flow is a measure of the time required for a specified quantity of powder to flow through an orifice of specified dimensions. It is a function of particle size distribution and shape but is also influenced by friction and other variables. Flow determines the time required to fill a die and thus determines the production rate that can be achieved.
