and flotation of the oxidized ores of lead. The method employed is the presentation of the actual o operation of several mills which have been treating such ores during 1926 and 1927. The plants described are representative operations and form some criteria for the perfor mance of such ores under different conditions. In addition to those concentrators which are described, there are perhaps ...
· This plant was formerly used to crush oxidized ore for chlorination and, being on the spot, it was naturally utilized in preference to buying new machinery. The crushed ore drops into a bin at the bottom of which are two Challenge feeders. These deliver the ore into a launder where it is met by a stream of water which carries it direct to a sixcompartment Minerals Separation machine. Each ...

AN INVESTIGATION INTO THE EFFECTS OF UG2 ORE VARIABILITY ON FROTH FLOTATION Ramlall, BSc (Eng), MSc (Eng), UKZN A thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy in the department of Chemical Engineering, University of KwaZulu–Natal January 2013 . i PREFACE As the candidate's supervisor I agree/do not agree to the submission of this thesis ...
therefore to say that the flotation circuits as existed in the early 80's were designed to recover the PGM minerals associated with base metal sulphides in Merensky ore. The challenge therefore was to design flotation circuits for the very different characteristics of the UG2 ores. The objectives were to: • maximise PGM recoveries despite the much reduced grain size of both the base metal ...
The relative density of Merensky ore is and that of UG2 ore is 15. b) Crushing costs are lower because UG2 ore is more friable. Milling costs are also lower. c) Flotation reagent costs are much lower, because Merensky ore requires the use of a talc depressant.
UG2 ore of the Bushveld Complex, these typically occur as sulfides, alloys, and to a lesser extent, as arsenides and tellurides, with fine grain sizes, generally <10 μm (McLaren and de Villiers, 1982; Penberthy et al., 2000). Their characterization is an integral component in metallurgical test work undertaken at Mintek. Over the years, a characterization scheme for PGM in flotation feeds ...
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. An effective processing method has not been found to recover copper and cobalt from this ore, which has been stockpiled for 4045 years in the idled plant. It was established that recovery of copper and cobalt ...
Finally the flotation performance of the ore from each environment was investigated, using small scale batch flotation experiments, to establish any linkage between the textures, the composition and the flotation performance of the chromite from different environments. In this study it was found that the UG2 normal reef and the UG2 reef affected by pothole formation are both principally ...
· The use of a sulphidizer to activate the oxidized lead minerals and control and/or removal of reagent consuming slimes is provided ahead of the oxidized zinc flotation section. Crushing Section The flowsheet uses a two stage open circuit crushing section with a capacity of 100275 tons per 24 hours to reduce the ore to minus ¾ inch for feed to the ball mill.

Flotation Behavior Of Iranian Oxidized Zinc Ore Using. Apr 01 Introduction Some of most important sources of zinc ore are oxidized zinc minerals including smithsonite ZnCO 3 willemite Zn 2 SiO 4 hydrozincite 2ZnCO 3 3ZnOH 2 zincite ZnO and hemimorphite Zn 2 SiO 3 H 2 O However flotation of oxidized lead and zinc in particular zinc minerals is much more difficult than the flotation ...
11. A method for enriching oxidized ores by froth flotation, wherein use is made, as collector, of a combination comprising (1) an aminolalkane of the formula R 1(NH CH 2 CH 2 CH 2)n NH 2. wherein R 1 is a saturated or unsaturated straight or branchedchain hydrocarbon group containing from 8 to 18 carbon atoms, and n is an integer ranging from 0 to 3, and (2) an aminoether of the ...
highchromite UG2 and the lowergrade Platreef ores, and less from the traditional Merensky Reef, which is historically the backbone concentrate feed to PGM smelters. The impact of higher chromite contents and lower PGM grades on smelter furnace efficiency and operating costs is of prime importance to the ongoing sustainability of the PGM industry. The mineralogy of PGM ores is complex, with ...

base metal sulphides from the UG2 ore of the bushveld complex. This was achieved through running a series of test work in a Denver flotation cell at varying pH 611 at constant reagent dosage. The UG2 reef is characterized by two predominant gangue phases chromite and silie, that have significantly different physical and chemical properties. The test work was aimed at evaluating which ...
Samples of UG2 ore, for expansion of current mining activities or new projects, are usually obtained using diamond drill core sampling. The sample mass obtained from this type of sampling is generally 2–3 kg. Therefore, the batch flotation test must be developed for a limited sample mass, and provide quantitative information on the changes in flotation response. The fitting of a batch ...
