The paper includes the results of laboratory studies for the copperbearing ore flotation with the use ofombined reagent. the combined flotation reagent was preliminarily passed throughzdna1200t ultrasonic disperser before flotation to obtaineagent microemulsion. the copper content in the concentrate was 21,5 with extrac.
Copper flotation circuits and were taken before entering the molybdenum circuit. the morenci coppermolybdenum concentrate analyzed 0.20.4 mo and 2833 cu, while the grade of the copperton coppermolybdenum concentrate was 2.54.1 mo and 3234 cu. the concentrates were received at 2035 solids. the particle size data show that the.
This tells us that the concentrate has 9.57 times the copper concentration of the feed. 1.1.1 graderecovery curves while each of these single calculated values are useful for comparing flotation performance for different conditions, it is most useful to consider both the grade and the recovery simultaneously, usingraderecovery curve.
It is worth noting that the main phase of the flotation concentrate was chalcopyrite asrimary sulphide, but the smelter dust mainly contained secondary copper sulphides such as cu2s, cus, and cu5fes4.under optimum conditions, copper dissolution from the combined flotation concentrate and smelter dust as an environmental hazard.
Copper flotation process summary. flotation of copper ores. although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs.
Results of flotation tests were unsuccessful in terms of both recovery and grade of concentrate product. the highest copper recovery of concentrate was found as 61.35 with 8.69 copper content. the concentrate with highest copper grade of 34.65 was obtained with only 26.98 copper recovery.
This paper developsomparative study based on several modeling methods for estimating the copper concentrate grade in the copper flotation process.

And the flotation process in mining consists of several steps performed to produceold concentrate copper. equipment used in the flotation process by usingtirred tank, and where the string of the tank is given airflow, so the gold and copper get price.
Both cases copper grade and copper recovery the parameter effects are. similar to be varied.aximum recovery of copper was 88,58 while the grade was.
Supplied to the main and control coppermolybdenum flotation. liquid glass was supplied to the collective copper and molybdenum concentrate refinery. it was supplied into the main and control flotation instead of the basic collecting agent of sodium butyl xanthate during flotation processing of ore usingombined flotation reagent.
1. flotation process are widely used for copper extraction. the ore pulp slurry is pumped to flotation cells for extracting.
Copper ore beneficiation methods. before the beneficiation of copper ores, crushing and grinding are required. the bulk ores are crushed to about 12cm byaw crusher orone crusher. then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.150.2mm.
A copper flotation flowsheet because the copper in this type of ore usually assays only plus or minusopper, the porphyry copper operations must be relatively large in order to be commercial. the flowsheet in this study.
Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. another important application is to reduce ash in fine coal and to remove fine pyrite from coal. the flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
These reagents have distinct functions and are added for three purposeso affect the faces of the minerals to be floated in suchay that they will adhere to the air bubbles introduced into the pulp in the flotation machines,o stabilize these bubbles in order to render possible the formation ofufficiently coherent froth, and.
Flotation is commonly used to concentrate copper sulfide minerals, such as chalcopyrite cufes 2. in this example, the production ofopper concentrate is investigated.
Flotation is commonly used to concentrate copper sulfide minerals, such as chalcopyrite cufes 2. in this example, the production ofopper concentrate is investigated. after mineralogical examination, we decided to divide the ore into four species for characterization cp 100 cufes cppy 95 cufes fes pyas 70 fes0.
The result is that window adaptive partial least squares method is the most accurate method, which can accurately predict the copper concentrate grade of the next measurement period in advance and can be used to guide operations. keywords modelinstima ion, copponcentrate gra e, copper flotation proce s. 1.
A modal examination of the products produced by the copper flotation rougherscavenger circuit reveal important information regarding the limits to the efficiency of the process, imposed by mineralogy, fragmentation and flotation capacity. lets discusses various aspects of rougher flotation circuit performance and how to evaluate its resultsrior to compositing the.
The flotation cells are divided into several parts roughing, concentration and scavenging the exact numbers of stages for each part should be decided by test work to reach the best recovery, and with the use of frothing agent and collecting agent, the copper concentrate will be collected.
