Copper Ore - an overview | ScienceDirect Topics
From plant practice, treating oxide copper and copper cobalt ores, two basic flotation methods are practiced: (a) sulphidization flotation method, and (b) anionic flotation method. 19.5.1 Sulphidization flotation method. This method is the most commonly used in beneficiation if oxide copper-bearing ore.

copper flotation plants was examined. According to the operations, the recovery of molybdenite in the rougher/scavengers of the bulk Cu/Mo flotation circuit was consistently lower than that of copper sulphide. Moreover, reducing the flotation feed solids percent led to an increase in molybdenite recovery whereas copper flotation was

Copper extraction - Wikipedia
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

MEI's Barry Wills: Challenges in copper flotation
How flotation continues to, and needs to, evolve is perhaps no better illustrated than by the case of copper, the commodity where it finds its most important use, and produces the greatest annual tonnage. Total world tonnage is around 15 million tonnes per year, and with developing countries demanding more each year, this is bound to increase.

Abstract. There are several mathematical models that search to optimize resources in different topics and areas. Chile being the largest copper producer in the world, where this natural resource is nonrenewable in the normal time frame, which means that over time these deposits will gradually have lower copper grades and then the cost of the process is increasing too.

Copper Mining and Extraction Sulfide Ores
Copper mines are only set up where there is more than 5 kg of copper per tonne of rock (0.5% by mass). Ideally, the figure should be closer to 2%. The world's largest copper ore deposits are found in Chile on the west coast of South America. This is due to the volcanic activity that is part of the process that created the Andes mountain chain.
