2. 2. Flotation Procedure All the flotation test-work was done using the Denver laboratory machine with a 1.5l stainless steel flotation cell. The required mass of nickel-copper sulphide ore material ground to 70% passing 75 µm was weighed and placed in the flotation cell. This was followed by the addition of distilled water to about


The Arizona Copper Co.'s plant will treat the slime and re-crushed sand from previous gravity-treatment; out of an original tonnage of 4000 there …


A concise flow diagram of the copper flotation process can be shown in Fig. 1.Raw ore is firstly conveyed to the ball milling. Next, the ball milling breaks the feeding ore into pulp slurry with a suitable particle size (minerals size should be under 200 mesh, i.e., less than 0.074 mm).Eligible slurry from ball milling is then fed into an agitated tank, where the valuable …


copper sulphide minerals and 93% of carrollite co uld be recovered from mixed oxide sulphide ore at ambient pH in a laboratory batch flotation experiment. Final concentrate grades after the sulphide flotation stage were 12.2% Cu and 0.38% Co [11]. Flotation processes are typically optimized through changes of reagent dosage and flotation


Sulphide ores are the major sources of base metals like Copper, Lead, Zinc, Nickel and Cobalt. Beneficiation of. these base metal sulphide minerals is …


Asynchronous flotation process is adopted for the smelting slag to preferentially recover coarse-grained copper minerals with good floatability under coarse grinding fineness. The copper concentrate with copper content of 45.36% and copper recovery of 81.65% was obtained.

Results of flotation tests of feeds non-classified and size-density fractions for separate copper ores' lithological types in a form of Fuerstenau upgrading curves, kinetics curves (figures 5-7) and in a form of technological indexes are presented in table 2. Figure 5.


flotation of cobalt oxides from already is best at the pH of about 7.5 [4]. The flotation of a mineral sulphide Cu-Co produce a Cu-Co bulk concentrate. During the flotation, Cu-Co float at natural pH or pH 11 using xanthate or dithiophosphate. This occurs when the copper mineralization as chalcocite.


The pulp density for froth flotation may be that conventionally employed, i.e.; on the order of from about 15 to 30 percent solids by weight. For oil extraction flotation, 0.1 to 10 percent solids is an acceptable range. In the oil extraction process, the volume of oil may be from 10 to 21 percent by volume of the aqueous pulp.


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 …


Two straight lines gave the best fit followed by quadratic model gave best fit followed by power model, and the other three models also gave good fit to the data for copper recovery as affected by pH of pulp in flotation process (Fig. 2) the X-max calculated from the quadratic equation show that 11.3 pH of the pulp will result in


This study is focused on the froth flotation reprocessing of a copper mineral from flotation tailings. The effects of flotation parameters including pulp density, collector dosage, frother dosage, and dispersant dosage were statistically examined to obtain an effective approach for concentrating copper minerals.


The goal is to grind the ore just enough for optimum copper mineral liberation in the froth flotation plant circuit. Under-grinding reduces recovery; overgrinding reduces throughput and wastes energy. Real-time particle size analysis in slurry is the key to effective grinding control in finer particle sizes prior to froth flotation.

In mineral flotation, rheological problems have limited the efficient upgrading of low-grade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.


The effect of the parameters such as pH, pulp density, particle size and collector amount were investigated. KAX was used as collector and Dow-250 was used as frother. Key Words: Sulfurization, flotation, copper, gold, silver 1. INTRODUCTION Flotation has been utilized in the mineral processing industry to concentrate base


The Effect of Sulfurization Process on Flotation of Copper Ore The mine sample was first crushed and then ground to160 mesh size, sieved and dried at 110 oC. The effect of pH on the flotation yield As seen in Figure 1, the best of flotation yield was at pH 11.0. Particle Size Analysis for Mining and Minerals . Froth Flotation.

RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan M.S., Department of Mining Engineering Supervisor: Prof. Dr. Mustafa Ümit Atalay December 2014, 65 pages The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching.


Thickener feed dilution is often used for enhanced flocculation and sediment compressibility. This work investigated the effect of feed dilution on thickener performance for copper flotation tailings.


Flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching. In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated ...
