The floatability of enargite 3Cu 2 2 S 5 has been determined as a function of pulp potential to establish whether the flotation behaviour of the mineral differs sufficiently from that of other copper minerals thus offering the prospect of rejecting arsenic from the Tampakan ore by potential control during The results of a single mineral flotation study reveal
A three factor three level face centered cubic FCC experimental design was used to study the effect of important chemical variables—collector chain length collector concentration and
The aim of this study is to apply process mineralogy as a practical tool for further understanding and predicting the flotation kinetics of the copper sulfide minerals The minerals composition and association grain distribution and liberation within the ore samples were analyzed in the feed concentrate and the tailings of the flotation processes with two pulp
Since June 2009 these mixed ores have been treated by flotation using controlled potential sulphidization This paper describes the development of the process and its optimization The effect of the complex mineralogy on the flotation performance is also depicted copper flotation mixed sulphide/oxide ore controlled potential sulphidazition
This paper presents the results of mineralogical and flotation studies on the copper ore from the deposit "North Revir" in the Copper Mine Majdanpek using different collectors
the zeta potential and Hallimond flotation tests to assess the role of operating parameters in flotation The distinctive role of process mineralogy and flotation chemical influence for copper mineral flotation of Nussir ore is presented in this article The Nussir ore primarily contains three copper minerals chalcopyrite chalcocite and
A flotation pre treatment study for the separation of enargite Cu3AsS4 from chalcopyrite CuFeS2 ores of different origins was investigated in this work The copper ore bearing enargite mineral Expand
This information is very crucial for optimising gold recovery in copper gold ore flotation It is well known that measured liberation values 2D from QEMSCAN and MLA may exceed the true liberation value in 3D in some systems depending on the type and complexity of the composites chalcocite etc and the copper arsenic bearing

In this study the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed This ore contains % copper % cobalt and % sulfur
Thionocarbamates are the group of collectors that are mostly used for flotation of sulphide copper minerals alone or in combination with xanthates depending on a mineralogical composition of the ore In this paper the results of the study of application of thionocarbamates in copper slag flotation are presented Chemical analysis of smelter slag sample obtained from
Copper content in the ore feed collector dosage in the rougher and the scavenger flotation circuits slurry pH in the rougher flotation circuit and frother consumption were selected as input parameters to estimate the copper grade and recovery of final concentrate as well as the copper content in the final tailings of the flotation plant
Application of the grade recovery curve in the batch flotation of Polish copper ore For instance for a chalcocite copper ore the maximum theoretical content is % because theoretical Cu content in Cu 2 S is % In many cases the separation line starts at another point on the grade axis The parameters which influence slope k in
With the depletion of chalcopyrite dominant copper ores more and more chalcocite dominant copper ores with a high pyritic content are treated There is a general industrial observation that chalcocite dominant copper ores are more difficult to treat in particular in cleaner flotation after regrinding Wightman et al 2011
Surface oxidation of secondary minerals such as chalcocite bornite and digenite present in the Salobo copper ore makes their flotation difficult and requires excessive reagent consumptions
1984 reported the use of nitrogen in the flotation of a mixed ore containing copper and molybdenum sulfides at ANAMAX Mining Company Arizona The closed industrial flotation machines were designed and manufactured by Wemco These machines had a system for recovering dissolved nitrogen in the flotation flows The consumption of the
Recently processing copper sulfide ores containing arsenic minerals such as enargite has been the subject of growing concerns Enargite Cu 3 AsS 4 an arsenic bearing copper mineral is usually associated with copper sulfide minerals such as chalcopyrite CuFeS 2 and chalcocite Cu 2 S [1] [2] [3] These arsenic bearing copper and copper sulfide
The aim of the paper was the analysis of the influence of milling time on the laboratory flotation of the copper ore from stratiform Polish deposit Three different milling time of copper ore in laboratory ball mill was applied The flotation results were presented as the recovery recovery and grade recovery upgrading curves
The total share of xanthates used in US plants is 60% dithiophosphates about 40% Suppressors of gangue minerals are not usually used in flotation of copper disseminated ores But if the pulp has an increased content of slimes then liquid glass up to g/t is added to the main copper flotation and to the copper concentrate re cleaning
