One of these has been the design of the flotation circuit to make the most of the liberation and surface chemistry effects of the minerals. ... the characteristics of the copper bearing minerals should suggest an appropriate grinding circuit P80 of between 100 and 200 μm (0.1 and 0.2 mm), which can be controlled by cyclones, or in some cases ...


Froth flotation entails crushing and grinding of the ore to obtain a proper liberation of particles to apply flotation principles. The process is conducted in water from the grinding circuit because it relies on the physical properties of the particles and water.


The flotation feed is the tertiary grinding overflow of 80% passing –65 µm. The copper flotation circuit includes rougher and scavenger flotations, as well as several recleaner stages when rougher and scavenger concentrates are reground with a recleaner concentrate. The rougher bulk concentrate contains 4% copper with 75% recovery.


In a typical grinding circuit at, for example, a copper mine, the ore is introduced in the mills where abrasion, attrition and impact reduce its size. Usually, the grinding circuit contains at least two interconnected mills with material classifiers (eg,cyclones) separating the fine material from the coarse (that then goes for regrinding).

circuit. Mass balancing of both grinding and flotation circuits was performed to calculate the flow rates in each stream. Laboratory flotation tests were also applied to the ore samples taken from feed of the primary grinding mill to determine the best flotation conditions and to compare the laboratory results with existing conditions.


Commercial copper production was declared on March 1, 2009, when copper concentrate inventory levels surpassed the 5,000 tonne shipping threshold. Increased zinc levels in the ore body, as it was continuously being mined, prompted the construction of a Cu/Zn separation circuit as extension of the previous flotation circuit.
