The ultimate goal of this operation is to select copper; for copper sulfide ore, according to its typical flotation characteristics, better and more complete formulation of the required process conditions. In the copper sulfur separation operation, due to the large amount of lime and the fine grinding particle size, it has a greater impact on the corresponding flotation of molybdenite; in the actual copper separation
Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work place applications, especially at Broken Hill, Australia, that brought the technological innovation known as froth flotation. During the early 20th century, it dramatically revoluti
Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores . Davenport, et al, noted in 2002 that even then 80% of global primary copper production was from copperironsulfur minerals and that the vast majority of these were treated by smelting. Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters
Beneficiation of copper ores is done almost exclusively by selective froth flotation. Flotation entails first attaching fine copper mineral particles to bubbles rising through an orewater pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineralwaterair froth.
Most kinds of minerals require coating with a water repellent to make them float. By coating the minerals with small amounts of chemicals or oils, finely ground particles of the minerals remain unwetted and will thus adhere to air bubbles. The mineral particles are coated by agitating a pulp of ore, water, and suitable chemicals; the latter bind to the surface of the mineral particles and make them hydrophobic.
