How is Copper Ore Processed - Mineral Processing & Metallurgy
The pulp is fed into the second cell of each bank and a sulphide rougher concentrate is produced from cells, 2, 3 and 4 and returned to the first cell for cleaning This cleaned sulphide copper concentrate is pumped by 3″ x 3″ DRL Pumps to the main sulphide cleaner concentrate pump box and thence to thickeners The sulphide copper tailings .
The Jameson Cell is a high-intensity froth flotation cell that was invented by Laureate Professor Graeme Jameson of the University of Newcastle (Australia) and developed in conjunction with Mount Isa Mines Limited ("MIM", a subsidiary of MIM Holdings Limited and now part of the Glencore group of companies)

A rougher concentrate is together produced by two parallel rougher flotation banks The rougher concentrate is processed and upgraded through a two stage flotation clean circuit A bulk concentrate with both copper and molybdenum is thickened to separate the two minerals using differential flotation The two minerals are dewatered to moisture .
Molybdenite flotation from copper/molybdenum concentrates ,
Typically, rougher molybdenite flotation and recovery from bulk copper/molybdenum concentrates involves the use of alkalisulfides, Nokes reagents, cyanides, oxidants, and/or thermal treatment to depress copper sulfide minerals The bulk copper/molybdenum feed generally varies from 02% Mo to 10% Mo, and with traditional reagents the single-stage rougher flotation recovery of molybdenite .
SOMINCOR- Soco Mineira de Neves- Corvo, SA, was formed on 24th of July 1980, after a sulphide deposit containing signiticant amounts of base metais, predominantly copper and zinc, was discovered in 1977 The initial discovery was made by consortium of the Portuguese State company EDM, Penarroya and BRGM There are tive massive sulphide orebodies: Neves, Corvo, Graça, Zambujal and ,

How Hydrometallurgy and the SX/EW Process Made Copper the ,
Copper is traditionally known as the "red" metal after its natural color However, it is also known as a "green" metal for the green patina that it acquires due to weathering Indeed, patinized copper is the architectural focal point of many modern buildings for its natural look

Modified-three-product column (3PC) flotation of copperâ ,
Copper–gold ores Tailings abstract Results of copper–gold rougher-ﬂash ﬂotation in a three-product column (3PC) are presented, and sepa-ration parameters are compared with results of an existing industrial small mill (rougher–scavenger– cleaner treating 100–120 t/day) This 3PC cell yielded 2%–5% richer Cu and Au concentrate .

A Comparison Between a Flotation Mini Pilot Plant and a Copper Concentrator Mill L M Loyola1 and K L C Gonçalves2 ABSTRACT In 1999, the Mineral Development Centre of CVRD (CDM) acquired a flotation device referred to as Mini Pilot Plant (MPP), which is able to run continuous flotation tests with drill core sampl Since then this
In this work, rougher flotation of low grade copper minerals (06–07% Cu) was tested in column cells at laboratory scale A negative bias regime was used in order to create a levitating effect on particle–bubble aggregates to promote gross particle flotation
process at a concentrator In the first flotation stage, as much copper as possible is recovered in a rougher concentrate so that as little as possible goes to the tailings To increase the copper recovery rate, often these tailings are leached with sulfuric ac After regrinding, the rough concentrate is ,
Introduction to Mineral Processing - Chevron Phillips Chemical
The froth, enriched in copper and molybdenum, is removed from the flotation roughers and scavengers This enriched material is now called the rougher concentrate or cleaner feed The combined rougher-scavenger concentrate may be 5% Cu and 006% Mo (a concentration factor of 3 to 10 times is typical)

This is not unusual when one considers the significance of the new submersible motor pumps for the processing of copper sulphide: The 10-inch pumps are used to dewater the copper sludge in the "flotation" process and extract the copper concentrate If the pumps fail, the production process comes to a standstill until the pumps are repaired
WO2014071485A2 - Process for removing uranium from copper ,
The present invention describes a process for removing uranium from a copper concentrate by magnetic separation (low and high field) aiming the reduction of the content of uranium in a copper concentrate to commercially acceptable levels
The goals for the rougher area are to maximize recovery, maintain acceptable rougher concentrate grade and to minimize reagent consumption Flotation Overload Recovery Strategy 1st – High Sump Levels: Evaluate the rougher concentrate sump level and lower pulp levels when the sump level is above the high limit
