Fine Grained Iron Ore Selective Flocculation and Flotation ,The latter term actually encompasses three steps; namely 1 dispersion 2 selective flocculation and 3 selective desliming. The ore being treated by selective flocculation was usually ground in the presence of sufficient sodium hydroxide to give a pH of about 10 to 10.5.

Chalcopyrite Cu Sphalerite Zn Separation by Flotation ,Metallurgical ContentThe Problem with separating Copper from Zinc by flotationThe Copper Zinc Process FlowsheetCRUSHINGROD MILLING The Problem with separating Copper from Zinc by flotation The treatment of heavy sulphide ores of copper containing zinc and pyrite is often extremely difficult particularly if soluble copper and sulphates are present. This is usually the case in ore deposits near .

Selective Flotation of Chalcopyrite and Pyrite from a Mixed . ,Description. A process that allows selective flotation separation of low Cu/S ratio minerals chalcopyrite and pyrite from high Cu/S ratio minerals bornite and chalcocite from a mixed copper mineral concentrate under controlled oxidative-reductive potential conditions has been developed.

Copper-Lead-Zinc ores ,Which flotation scheme used in the differential copper-lead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate. Whichever mineral constitutes the lower bulk concentrate mass will be floated away from the other mineral which is depressed for flotation selectivity reasons.

CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION TO . ,employing flotation on commercial scale for processing of iron ore. The most noted one is the Tilden Mine of Michigan where amine flotation is used in addition to selective flocculation and desliming. But considering the present scenario the recent developments such as column flotation technology it should be possible to extend the PIO-07 103

How to Process Copper Ore: Beneficiation Methods and . ,Copper sulfide can be divided into single copper ore copper sulfur ore copper-molybdenum deposit copper nickel carrollite and so on. Basically only flotation can be considered in its separation. Almost all copper sulphide ores contain iron-bearing sulfides so in a sense the flotation of copper sulfide is essentially the separation of .

Some Reasons for Selectivity in Copper Activation of Minerals ,In zinc flotation the great value of copper sulphate results from its ability to activate zinc sulphide preferentially to gangue minerals. At the Sullivan Concentrator of The Consolidated Mining and Smelting Company of Canada Limited the most abundant gangue mineral in the lead-zinc ore is pyrrhotite and the zinc mineral is marmatite of .

Froth flotation - Wikipedia ,Froth flotation depends on the selective adhesion of air bubbles to mineral surfaces in a mineral/water slurry. The air bubbles will attach to more hydrophobic particles. The attachment of the bubbles to the surface is determined by the interfacial energies between the solid liquid and gas phases.

Flowsheet for treatment of Copper Sulfide ores rich in minerals such as chalcopyrite with gold and silver as well as arsenopyrite The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values The ore ranging from 6065 silica with pyrite arsenopyrite and calcite with 3 to 4 copper This flowsheet .

EFFECTS OF EDTA ON SELECTIVE FLOTATION OF SULPHIDE MINERALS ,copper minerals mainly chalcopyrite hampers flotation selectivity. Galvanic interaction between the sulphide minerals is considered as the main cause for such activation. Therefore a complexing agent EDTA was used to prevent unwanted activation of sphalerite and pyrite by copper ions in the presence and absence of collector.
