copper process flowsheet example

Oct 01, 2015 A simplified schematic drawing of copper flotation flowsheet. Run-of-mine open pit ore will be crushed in a gyratory crusher. The crushed ore will be processed by means of semi-autogenous and ball mill grinding followed by rougher flotation, regrind, cleaner flotation, and dewatering to produce copper concentrate. The concentrate will be trucked via the existing road network in the area to a port

tracking comminution energy and optimising grind size for

The main purpose of comminution is liberating minerals for economic recovery. With metal prices down, long term challenges of declining ore grades and increasing ore hardness, and climate change causing new constraints and costs on energy, the mining industry needs to stay focused on minimizing energy use in metal production, including comminution

The paper presents the results of analyze the particle size distribution function of comminution products of dolomitic type of copper ore. The breakage tests for single irregular particles were performed with using a hydraulic press device. The authors prepared five particle size fractions of each material, within ranges: 16-18 mm, 18-20 mm, 20-25 mm, 25-31,5 mm and 31-45 mm
